lenovo t400 lcd panel free sample

Lenovo ThinkPads are a commonly used laptop in personal computing. Like all mobile products, however, screens can sometimes become damaged or cracked. If you need to repair or replace the LCD screen on your Lenovo ThinkPad, here are some answers to some commonly asked questions.How do you choose the right screen?

In order to get the right replacement screen for your ThinkPad, you will need to know the model number. Depending on when your ThinkPad was manufactured, there are several ways to find the model number. On some ThinkPads, the model number will be printed directly onto the bezel (case) below the LCD screen. On most laptops, the machine type (model number) will also be printed on a label on the bottom of the laptop. If the label is missing, damaged, or illegible, there are still a few other ways to find that information. Here are some other ways to find the model information for your ThinkPad:Check under BIOS.

Many LCD displays are actually comprised of two different parts: the LCD itself and a glass cover. In some cases, the LCD screen itself is fine; it is just the glass cover that needs to be replaced. In other cases, the entire LCD display needs to be replaced. If just the glass cover needs to be replaced, keep in mind that the LCD screen itself can still become damaged while replacing the glass cover. When ordering a replacement screen, it is important to make sure you know what you are getting. Some offers are for the glass cover by itself, some are for just the LCD screen and glass, and others are for the entire top half of the laptop, including the LCD, glass, and outer case. In many cases, replacing the entire top half of the laptop can be simpler and less time-consuming than replacing the LCD or glass. Replacing the entire top half of the laptop also generally requires less technical capability.Can screens be upgraded?

Many parts on Lenovo products can be upgraded to improve a ThinkPad"s speed or performance, but a screen is not one of them. Each screen is specifically manufactured and calibrated for a specific Lenovo product. Each product also needs specific drivers to operate specific screens as well. Though the size of a screen may be exactly the same from one Lenovo product to another, they are not interchangeable. You need to be sure, when ordering a replacement part, that you are ordering a part specifically designed for your model of ThinkPad. For example, if it is designed for a 14-inch screen, you need to order one exactly that size.

I want to ask if somebody know why there are 2 internal displays detected on my ThinkPad T400 on Win 8.1. I don"t remember if it detect 2 displays also on other systems but I think yes.

As Value Line models are thought for private users, under the name "ThinkPad" devices are found for professional use. The T-series tries straddling between performance, power efficiency and portability besides a row of other ThinkPad series. Read more to find out how successful the tested T400 (Type: 6474-19G, also known as NM819GE) takes this challenge.

The T400 with a 14.1 inch display belongs to the current model range of the T-series just like the bigger T500 models with a 15.4 inch widescreen display. Together they become heir to the previous T61 models. In opposition, the Txxp models, thus the more efficient mobile workstations are relieved from the W-series, which encloses the recently tested W700 (17 inch) besides the ThinkPad W500 (15.4 inch).

The T400 models are offered in numerous different configurations. These differ not only in view of the performance-bearing components (CPU, GPU, hard disk and main storage capacity), but also in consideration of display technology and available features. Our colleagues from Notebookreview had another model with a High-Nit LED display, a bigger RAM capacity and faster hard disk (link to their test report) in the test. It"s not surprising that this model cut off better in regards to display brightness and performance. Besides this, there are also models with an independent ATI Mobility Radeon 3470 available.

Apart from the smaller measurements of 335 millimeters breadth, 239 millimeters depth and 31.9 millimeters height, the case of the T400s is similar to its bigger counterpart, theweak points in the area of the Ultrabay-Drive slot and on the plastic cover over the keyboard. The case may possibly give away a bit under point pressure and creak if not even crackle (in the area of the optical drive).

Apart from the hard disk, which can be changed with the removal of only one screw, the maintenance of the T400s isn"t easy. In order to, for instance, expand the main storage you have to remove five screws from the notebook"s bottom side so that you can access the system components after removing the keyboard and touchpad.

The ThinkPad T400 offers all important ports. There are three USB ports, which are, unfortunately, placed vertically. Therefore the use of somewhat thicker USB sticks with this notebook isn"t optimal.

Lefties won"t be too pleased about the two, fairly far in the front of the left side positioned USB ports. Possible connected network cables, modem cable and VGA cable could provide for an additional restriction of the free work surface, which are all pretty much in the middle of the left edge. Aside from that, the left side also has a PC Card slot and an Express Card/54 slot. The good news: There is a docking stationon the bottom side of the T400s, which could ban annoying cables to the back side of the notebook.

Quite a bit of accessories are available for the ThinkPad T400, for instance various notebook cases, diverse docking solutions and batteries, alternate configurations for the Ultrabay-Drive slot (Blu-Ray, second hard disk, battery and external input devices).

In regards to warranty, Lenovo offers 3 years of worldwide "bring-in" guaranty on the T400. The notebook has to be sent in, in case of a failure. For an "on-site" service with next working day response you have to attain an own warranty extension, which makes about 100.00 Euros more. If you would even like to extend to a 4 year "on-site" service, you have to count with about 108.00 Euros.

Lenovo currently offers two different display variations for the Thinkpad T400. Both have a resolution of 1440x900WXGA+. As some models are equipped with an LED illuminated display, our test model makes use of the CCFL technology. The LED panel provides for a higher brightness and better illumination.

The T400 offers extensive configuration options in regards to hardware equipment in order to appeal to the largest possible clientele and to fit the notebook perfectly to the individual needs of each single user. Being based on the Montevina platform, it can be equipped with a whole row of Core 2 Duo processors with vPro technology. Our test model had a P8600 processor with 2.4 GHz, which delivers an excellent price for value ratio.

An integrated Intel GMA 4500MHD graphic chip was responsible for the graphic in the tested T400. In compliance there are also models with a hybrid graphic solution available, though. Depending on the efficiency need or energy savings requirement at mobile use an alteration between the integrated Intel GMA 4500 MHD chip and a dedicated ATI Mobility Radeon HD 3470 graphic card can be made. This modification function can be executed under Windows Vista even when being used.

The ThinkPad T400 can be equipped with up to 4 GB RAM, according to the manufacturer"s declaration. There were two fast 1024 MB DDR3 (PC-8500) memory bars built into the tested model. Therewith both RAM slots were occupied and for an upgrade at least one of these two chips has to be exchanged.

Depending on the configuration the various hard disks are used in the ThinkPad T400. Aside from the usual hard disks with 5400 rpm and 7200 rpm, also Solid State Drives (SSD) can be chosen from. The appliance of a second hard disk via the Ultrabay-Drive slot is also thinkable. Either you can increase the total storage capacity or provide for additional data security through drive mirroring with that.

The from us tested T400 model reached 5013 PCMarks in the PCMark05, whereas the tested model from Notebookreview reached with 5305 PCMarks, a better performance of 6%. This relatively small difference results out of the larger main storage capacity and the faster hard disk (7200 rpm) in the from Notebookreview tested model. In comparison to the T500 (DDR2 RAM) is to note: a fast DDR3 RAM, for instance in both T400 models in regards to performance is advantageous.

Our test candidate is therefore well equipped for basic office functions and internet. De facto, these applications and also simple image processing ran smoothly and barely had interruptions. This device is neither designed nor equipped for sophisticated games. A ThinkPad T400 model with a dedicated ATI Mobility Radeon HD 3470 graphic card might prove to be beneficial for 3D applications.

Just like in the Thinkpad T500, a 6 cell lithium-ion battery with a capacity of 5200 mAh (56.16Wh) is applied in the ThinkPad T400 from Lenovo. Alternately a larger 9 cell battery is also offered for the T400 as well as an Ultrabay supplementary battery.

The 6 cell battery already protrudes slightly out of the back side of the case. Besides that, it is an identical assembly part as used in the previous T61 models. The new Ultrabay battery can be used in older models, but older Ultrabay batteries, in opposition to the 9 cell main battery, not in the new T-series models, T400 and T500.

The included 6 cell battery shows the same weaknesses as those in the T500: It also sits in the T400 with a very sizeable gap in the case and wobbles somewhat in a docked state.

In theBatteryEater Reader"s test at minimum brightness, activated energy savings profile and deactivated WLAN, it delivered amaximum runtime of 266 minutes (4 hours, 26 minutes). The T400 still survived98 minutes (1 hour 38 minutes) under load in the BatteryEater Classic test. With an activated wireless module you can work for approx. 175 minutes (2 hours, 55 minutes) without a break before you have to charge the battery again. DVD movies can be enjoyed for up to 127 minutes (2 hours, 7 minutes) with the 6 cell battery without a break.

With the T400 Lenovo managed to design a professional notebook with communication features and a good mobility once again. The main focus of the tested notebook, with Intel Core 2 CPU and integrated GMA 4500 MHD graphic chip, lies definitely on office and internet applications. If there is more need for 3D performance, you may find these in the T400 models with hybrid resolution. The allow changing between the integrated graphic chip and a dedicated ATI Mobility Radeon HD3470, depending on performance requirements or rather energy savings requirement.

An office notebook like the Lenovo ThinkPad T400 also benefits from the very low emissions. This applies just as well to the notebook"s soundscape as to the surface temperature, which always stays within a limit.

Conclusively you can say that the Lenovo T400 office notebook can be recommended for professional or private users, who put value on an extensive mobility but don"t want to or can"t completely sacrifice certain performance reserves.

ThinkPad is a line of business-oriented laptop computers and tablets designed, developed and marketed by Lenovo, and formerly by IBM until 2005, when IBM"s PC business was acquired by Lenovo.trackpoint on the keyboard, which has become an iconic and distinctive design characteristic associated with the ThinkPad line.

The ThinkPad was developed to compete with Toshiba and Compaq, who had created the first two portable notebooks, with an emphasis on sales to the Harvard Business School. The task of creating a notebook was given to the Yamato Facility in Japan, headed by Arimasa Naitoh(内藤在正, Naitō Arimasa, now Lenovo Fellow and vice president of Lenovo"s PC and Smart Devices business unit),

In 2005, Lenovo purchased the IBM personal computer business and the ThinkPad as a flagship brand along with it. Speaking about the purchase of IBM"s personal computer division, Lenovo founder Liu Chuanzhi said, "We benefited in three ways from the IBM acquisition. We got the ThinkPad brand, IBM"s more advanced PC manufacturing technology and the company"s international resources, such as its global sales channels and operation teams. These three elements have shored up our sales revenue in the past several years."

Although Lenovo acquired the right to use the IBM brand name for five years after its acquisition of IBM"s personal computer business, Lenovo only used it for three years. Today Lenovo manufactures and markets Think-branded products while IBM is mostly responsible for overseeing servicing and repairs for the Think line of products produced by Lenovo. Both IBM and Lenovo play a key role in the design of their "Think" branded products.

The majority of ThinkPad computers since the 2005 acquisition of the brand by Lenovo have been made in Mexico, Slovakia, India and China. Lenovo also employs ~300 people at a combined manufacturing and distribution centre near its American headquarters. Each device made in this facility is labelled with a red-white-and-blue sticker proclaiming "Whitsett, North Carolina."

The design language of the ThinkPad has remained very similar throughout the entire lifetime of the brand. Almost all models are solid black inside and out, with a boxy, right-angled external case design. Some newer Lenovo models incorporate more curved surfaces in their design. Many ThinkPads have incorporated magnesium, carbon fiber reinforced plastic or titanium into their chassis.

The industrial design concept was created in 1990 by Italy-based designer Richard Sapper, a corporate design consultant of IBM and, since 2005, Lenovo.

Earlier known as "IBM Access", later "ThinkVantage", the Lenovo Vantage is a suite of computer management applications. This software can give additional support for system management (backup, encrypting, system drivers installation and upgrade, system monitoring and others). Currently some old features have been replaced by internal Windows 10 features.

External keyboard light, replaced by internal backlight; is an LED light located at the top of the LCD screen which illuminates the keyboard from above.

The keyboard design was replaced by the Chiclet style keyboard (2012-current) — The keyboard adopted by Lenovo in 2012 over the original IBM keyboard design. And does not support the ThinkLight to illuminate the keyboard, instead using a keyboard backlight. (Some ThinkPad models during the intermission period between the classic IBM design and the Lenovo chiclet design could be outfitted with both the backlit chiclet style keyboard and the ThinkLight.)

Some Lenovo laptops (such as the X230, W530 and T430) block third-party batteries. Lenovo calls this feature "Battery Safeguard". It was first introduced on some models in May 2012. Laptops with this feature scan for security chips that only ThinkPad-branded batteries contain. Affected Thinkpads flash a message stating "Genuine Lenovo Battery Not Attached" when third-party batteries are used.

IBM took its first steps toward ThinkPads with an alternative operating system, when they quietly certified the 390 model for SUSE Linux in November 1998.Linux-based unit with the ThinkPad A20m in July 2000. This model, along with the closely-released A21m, T21 and T22 models, came preinstalled with Caldera OpenLinux.Red Hat Linux, SUSE Linux Enterprise, and Turbolinux by means of customer installations on A30, A30p, A31p models. This continued through the Lenovo transition with the T60p, until September 2007.

In 2020, Lenovo shifted into much heavier support of Linux when they announced the ThinkPad X1 Carbon Gen 8, the P1 Gen 2, and the P53 would come with Fedora Linux as an option.P series lineup.

The ThinkPad Yoga is an Ultrabook-class convertible device that functions as both a laptop and tablet computer. The Yoga gets its name from the consumer-oriented IdeaPad Yoga line of computers with the same form factor. The ThinkPad Yoga has a backlit keyboard that flattens when flipped into tablet mode. This was accomplished on 1st generation X1 Yoga with a platform surrounding the keys that rises until level with the keyboard buttons, a locking mechanism that prevents key presses, and feet that pop out to prevent the keyboard from directly resting on flat surfaces. On later X1 Yoga generations, the keys themselves retract in the chassis, so the computer rests on fixed small pads. Touchpad is disabled in this configuration. Lenovo implemented this design in response to complaints about its earlier Yoga 13 and 11 models being awkward to use in tablet mode. A reinforced hinge was required to implement this design. Other than its convertible form factor, the ThinkPad Yoga retains standard ThinkPad features such as a black magnesium-reinforced chassis, island keyboard, a red TrackPoint, and a large touchpad.

In order to celebrate the 20th anniversary of the ThinkPad, Lenovo held a large party in New York where it announced several products, including the Tablet 2. Lenovo says that the ThinkPad Tablet 2 will be available on 28 October 2012 when Windows 8 is released.Windows 8 Professional operating system. It will be able to run any desktop software compatible with this version of Windows.

Announced in May 2014, Lenovo ThinkPad 10 is a successor to the ThinkPad Tablet 2 and was scheduled to launch in the summer of 2014 along with accessories such as a docking station and external detachable magnetic keyboards. It used Windows 8.1 Pro as its operating system. It was available in 64 and 128GB variants with 1.6GHz quad-core Intel Atom Baytrail processor and 2GB or 4GB of RAM. It optionally supported both 3G and 4G (LTE). Display resolution was announced to be 1920 × 1200, paired with a stylus pen.

The E Series is a low-cost ThinkPad line, designed for small business mass-market requirements, and currently contains only a 14" and 15" sub-lines. The E Series line of laptops replaced Lenovo"s Edge Series, but somewhere (in some countries) currently (May 2019) offered as both of "Thinkpad Edge/E series" names. The E series also lack metals like magnesium and carbon fibre in their construction which other members of the ThinkPad family enjoy.

The T series historically had high-end features, such as magnesium alloy roll-cages, high-density IPS screens known as FlexView (discontinued after the T60 series), 7-row keyboards, screen latches, the Lenovo UltraBay, and ThinkLight. Models included both 14.1-inch and 15.4-inch displays available in 4:3 and 16:10 aspect ratios.

The Tx20 series ThinkPads came in two editions: 15" (T520) or a 14" (T420). These are the last ThinkPads to use the classic 7-row keyboard, with the exception of the Lenovo ThinkPad 25th anniversary edition released on Oct. 5, 2017, which was based on the ThinkPad T470.

Over time, The T series ThinkPad"s purpose has changed. Initially, the T series ThinkPad was meant to have high-end business features and carry a 10–20% markup over the other ThinkPads. Starting with the T400, The ThinkPad T series became a less of a high-end business laptop and became more suited as a mobile workstation, becoming similar to the W-series or P-series ThinkPads. Achieving similar performance to the W-series, but with a 5–10% smaller profile than the W-series ThinkPads. In 2013, the T440 introduced another major shift in The ThinkPad T series. The ThinkPad became more of an overall office machine than a mobile workstation. By today"s standards, The ThinkPad T series is thicker than most of its competitors.

The mainstream current "workhorse" models is a X13 and X13 Yoga, the 13" successors of the classic discontinued 12" line of Lenovo X Series ThinkPads.

The P Series line of laptops replaced Lenovo"s W Series and reintroduced 17" screens to the ThinkPad line. The P Series (excluding models with "s" suffix) is designed for engineers, architects, animators, etc. and comes with a variety of "high-end" options. All P Series models come included with fingerprint readers. The ThinkPad P Series includes features such as dedicated magnesium roll cages, more indicator LED lights, and high-resolution displays.

An external USB 3.0/2.0 hard drive that was designed by Lenovo in 2009. It requires the input of a 4 digit PIN to access data and this can be set by the user.

The 600-series (600, 600E, and 600X) are the direct predecessors of the T series. The 600-series packed a 12.1 in (310 mm) SVGA or a 13.3 in (340 mm) XGA TFT LCD, Pentium MMX, Pentium II or III processor, full-sized keyboard, and optical bay into a package weighing roughly 5 lb (2.3 kg). IBM was able to create this light, fully featured machine by using lightweight but strong carbon fiber composite plastics. The battery shipped with some 600-series models had a manufacturing defect that left it vulnerable to memory effect and resulted in poor battery life, but this problem can be avoided by use of a third-party battery.

This model was initially known inside of Lenovo as the "Scout". This was the name of the horse ridden by Tonto, the sidekick from the 1950s television series The Lone Ranger. Lenovo envisioned the Scout as a very high-end ThinkPad that would be analogous to a luxury car. Each unit was covered in fine leather embossed with its owners initials. Extensive market research was conducted on how consumers would perceive this form factor. It was determined that they appreciated that it emphasised warmth, nature, and human relations over technology. The Scout was soon renamed the ThinkPad Reserve Edition. It came bundled with premium services including a dedicated 24-hour technical support hotline that would be answered immediately. It was released in 2007 and sold for $5,000 in the United States.

The W-series laptops were introduced by Lenovo as workstation-class laptops with their own letter designation, a descendant of prior ThinkPad T series models suffixed with "p" (e.g. T61p), and are geared towards CAD users, photographers, power users, and others, who need a high-performance system for demanding tasks. The W-series laptops were launched in 2008, at the same time as the Intel Centrino 2, marking an overhaul of Lenovo"s product lineup. The first two W-series laptops introduced were the W500 and the W700.

Previously available were the W7xx series (17" widescreen model), the W500 (15.4" 16:10 ratio model), the W510 (15.6" 16:9 ratio model), and W520 (15.6" 16:9 ratio model). The W700DS and the W701DS both had two displays: a 17" main LCD and a 10" slide-out secondary LCD. The W7xx series were also available with a Wacom digitizer built into the palm rest. These high-performance workstation models offered more high-end components, such as quad core CPUs and higher-end workstation graphics compared to the T-series, and were the most powerful ThinkPad laptops available. Until the W540, they retained the ThinkLight, UltraBay, roll cage, and lid latch found on the T-series. The W540 release marked the end of the lid latch, ThinkLight, and hot-swappable UltraBays found in earlier models.

The ThinkPad W-series laptops from Lenovo are described by the manufacturer as being "mobile workstations", and suit that description by being physically on the larger side of the laptop spectrum, with screens ranging from 15" to 17" in size. Most W-series laptops offer high-end quad-core Intel processors with an integrated GPU as well as an Nvidia Quadro discrete GPU, utilizing Nvidia Optimus to switch between the two GPUs as required. Notable exceptions are the W500, which has ATI FireGL integrated workstation-class graphics, and the W550s, which is an Ultrabook-specification laptop with only a dual-core processor. The W-series laptops offer ISV certifications from various vendors such as Adobe Systems and Autodesk for CAD and 3D modeling software.

The Lenovo ThinkPad Twist (S230u) is a laptop/tablet computer hybrid aimed at high-end users. The Twist gets its name from its screen"s ability to twist in a manner that converts the device into a tablet. The Twist has a 12.5" screen and makes use of Intel"s Core i7 processor and SSD technology in lieu of a hard drive.

In a review for Engadget Dana Wollman wrote, "Lately, we feel like all of our reviews of Windows 8 convertibles end the same way. The ThinkPad Twist has plenty going for it: a bright IPS display, a good port selection, an affordable price and an unrivaled typing experience. Like ThinkPads past, it also offers some useful software features for businesses lacking dedicated IT departments. All good things, but what"s a road warrior to do when the battery barely lasts four hours? Something tells us the Twist will still appeal to Lenovo loyalists, folks who trust ThinkPad"s build quality and wouldn"t be caught dead using any other keyboard. If you"re more brand-agnostic, though, there are other Windows 8 convertibles with comfortable keyboards – not to mention, sharper screens, faster performance and longer battery life."

In a review published in Forbes Jason Evangelho wrote, "The first laptop I owned was a ThinkPad T20, and the next one may very likely be the ThinkPad Helix which Lenovo unveiled at CES 2013. In a sea of touch-inspired Windows 8 hardware, it"s the first ultrabook convertible with a form factor that gets everything right. The first batch of Windows 8 ultrabooks get high marks for their inspired designs, but aren"t quite flexible enough to truly be BYOD (Bring Your Own Device) solutions. Lenovo"s own IdeaPad Yoga came close, but the sensation of feeling the keyboard underneath your fingers when transformed into tablet mode was slightly jarring. Dell"s XPS 12 solved that problem with its clever rotating hinge design, but I wanted the ability to remove the tablet display entirely from both of those products."

Lenovo released the 25th anniversary Retro ThinkPad 25 in October 2017. The model is based on the T470, the difference being it having the 7-Row "Classic" keyboard with the layout found on the −20 Series, and the logo received a splash of colour reminiscent of the IBM era. The last ThinkPad models with the 7-row keyboard were introduced in 2011.

While this isn"t the first time Lenovo had offered an AMD derived ThinkPad, it is the first to be released as an alternative premium offering to the established T Series and X Series ThinkPads, which use Intel chipsets instead.
