lenovo t420 lcd panel replacement instructions manufacturer

This is not the Lenovo Thinkpad T420. You can Tell by the RAM memory Slot Cover and the Position the RAM is put into its slot. the T420 RAM is Vertical Compared with being Horizontal in this Picture. that includes the cover also. Then the Battery Slot is a Dead Giveaway clue. The T420 Battery slot is in the middle. and this Picture has the battery slot to bthe left. Sorry Not Even Close. None of the screws he removes are on the T420. so this is Completely Useless. Thanks

The T420/T430 generally come with a 1366x768 HD screen. However, it is capable of using a higher resolution 1600x900 HD+ screen; the extra pixel density and vertical space is a game changer for programmers.

If you forgot to purchase the upgrade from Lenovo when you bought your computer, follow this guide to do so. However, the process requires quite a bit of disassembly, since the default HD cable must be replaced.

If you want to try and install the X1 Carbon"s beautiful panel instead, check out this guide. Unfortunately, with that mod the LCD cable has to be extended, so it can be daunting.

There are three manufacturers that make the 1600x900 HD+ screen; Samsung, LG Philips, and AUO. Many fans believe that the Samsung screens are the best, and the AUO screens are the worst. The panels generally cost around $50. Search for these FRU numbers on eBay.

For the actual nitty-gritty details, follow the Lenovo Hardware Maintenence Manual for now. As you proceed, some minor parts don"t have to be removed (e.g. speaker assembly, LCD unit and integrated camera), so skip over such sections.

Instructions for replacing the LCD cable can be found on Lenovo website: "LCD panel and LCD cable removal and installation - ThinkPad T430 and T430i".

There are many LCD screen manufacturers for the Laptop Industry. LCD screens have different resolutions, size and type and these screens are compatible as long as the resolution and connections are the same.

For this listing, we will ship you a brand new OEM Compatible LCD screen manufactured either by Samsung, LG, Chi Mei, Chunghwa, Sharp, or AUOptronics. For more information about each LCD manufacture please click here.

If you wish to know the make of the actual LCD that will be shipped to you, please contact us by phone with your order information between 10AM - 8PM EST (Monday – Friday).

If you have a ThinkPad T420/T420S/T430/T430S laptop, I have great news for you: You can replace the screen with something that doesn’t suck!  It’s a bit of moderately deep laptop surgery, but it’s doable!

The replacement is fairly straightforward - but it does involve diving pretty deep into the laptop, and it does involve a sketchy bit of display translator hardware.  So, what’s involved?  Keep reading to find out!

Unlike most other laptops, the screen is genuine, Grade A rubbish.  It’s a TN display (the kind that changes color as you look at it from different angles), and it’s one of the worst TN displays you’ll ever see in your life - it’s absolute crap.  There’s been a lot of interest in replacing it - and, now, in 2019, there’s a pretty much bolt-in solution that solves the problem by letting you put a very nice IPS panel in your T420/T430 series ThinkPad!

The T4{2,3}0{,S} laptops (along with many others) use Low Voltage Differential Signaling (LVDS) to talk to the display.  This is an old technology, and is common in laptops for short range, high bandwidth links - say, between the GPU and the LCD.  It’s a low voltage system with a quite small signaling voltage (350mV), and while it requires quite a few pairs for high bandwidth, the power consumption is very low, and it’s “good enough” for most lower resolution displays.  Like RS485, which I’ve mentioned a few times here, it uses differential signaling - one signal line in a pair goes high, one line goes low.  This allows for rejection of common mode interference - by subtracting the signals from each other at the remote end, common interference cancels out and the signal is strengthened.

Embedded DisplayPort (eDP) is a far newer protocol - it’s DisplayPort, for laptop displays.  DisplayPort is a packet-based communication protocol, similar in many ways to PCI Express.  This is what many external monitors use now, and it’s what modern IPS panels use in most laptops.

Until around 2015, when some people from China built an adapter!  This little gizmo takes the LVDS signal on the input, and outputs an eDP signal for using a modern LCD!  It’s around $70 as a standalone unit on eBay, and involves either a small microcontroller or FPGA (I couldn’t read the numbers and wasn’t about to dismantle this device) to handle translation.  If you can find a kit with an LCD, go for that - it’s likely to be cheaper.  Otherwise, pick up one of the recommended LCD models as well (the eBay listings include a list of supported LCDs).

Is this sort of gizmo a good idea to put in your laptop?  Well, that’s up to you.  An inspection of the device showed no particularly obvious PCB antennas, and nothing wireless-transmitter-looking, though I can’t totally discount the possibility that there’s some sort of interesting capability buried in here.  However, it works without any driver support on the host - so if it is malicious, it has no easy way to transmit information out to the internet, and if someone’s close enough to pick up RF emissions, they likely can just look at the screen.  If it required host drivers, that would probably have been enough to convince me to not use it, but an inline LVDS to eDP converter is a thing that seems reasonable enough.  I’m comfortable with it for a typical home laptop, though I probably wouldn’t put it in a business laptop.  Lenovo is a Chinese company at this point, so another Chinese gizmo in the display path just doesn’t increase the risk that much.

I’m going to assume you’re “mostly competent” inside a laptop here - if you need really detailed teardown instructions, this project might be a bit over your head (or you can find tutorials on YouTube).  Lenovo laptops are genuinely easy to pull apart, but they’re still complex electronic devices with an awful lot of screws.

I’ve worked on many, many laptops before, and I’ve talked about that a bit more in the past.  A modern Lenovo is a genuine joy to work on - nothing too hidden, and a reasonable number of screws that mostly match each other (instead of, say, nearly 100 screws of 17 or 25 different varieties, like some years of Powerbook).

The keyboard comes out by sliding it.  You pop the surround off from around the power/volume/etc switches (start from the right), then slide the keyboard one way or the other (I think you slide it up, but could be down - it’s obvious if you play with it), and the whole thing comes out.  You’ll see the mainboard on the left, the drive cage for the optical drive on the right, and a bunch of cables that have to come out.  I like that Lenovo leaves long enough cables - the keyboard cable is long enough to slide the keyboard fully down before having to release it, and some other laptops aren’t nearly so nice.

You might be able to find replacement stickers on eBay, but you shouldn’t need to (and those are seriously expensive - if the stickers get messed up, just rock the screwy industrial look).

Once you have all the wires removed from the top case, you’ll need to replace the actual LCD - which, of course, is the whole point of this particular project.

The old screen comes out easily enough with 4 screws.  Before you put the replacement panel in, you’ll want to hook up the eDP connector - it’s on the backside.  This comes from the adapter board, and has a metal pull ring to remove it.  Make sure it’s seated - it takes a bit of force to seat it fully.  If it hasn’t slid a few mm, it’s not seated - and, of course, nothing will work.  Flip the pull ring around the top and it helps keep everything from wiggling apart.  Nicely designed!

The new screen bolts in as a direct replacement to the old one - which is why these kits are nice.  You don’t have to do any modifications to the screen or case!  Again, while you’re in here, give the other screws in the display bezel a quick twist.  Some of the webcam screws had worked a bit loose over the past few years - you may as well tighten them while you have things open!

I cannot describe in words (or picture) just how much better the new display is.  You may see ads showing a washed out display compared to a vivid display when looking at it from an angle, and they’re right on.  If anything, they understate the difference.  A modern IPS panel is so much better than the stock TN panel.  It amazes me to see the colors not shifting if I walk past the laptop now - rather jarring, really, when used to the “Oooh, what color is it botching now?” game.

I have managed to connect two external monitors (in addition to the built-in panel) to my ThinkPad T430 on Ubuntu 13.04, with Optimus ("Switchable graphics") enabled (option 3 in your list). The monitors are connected via the DVI interface, one of them is rotated. In contrast to other solutions, all monitors are attached to the same window manager, so windows can be moved freely between the monitors. This achieves the goal of enhanced battery life if disconnected and using external monitors if connected.

Have you ever faced a situation in which you opened your laptop or ThinkPad and saw nothing but a constant black screen? Looks disaster, right? But don"t worry. Your Lenovo desktop black screen is not a big issue to solve! There could be various reasons for this issue. It could be a loose GPU connection, damaged port, or a faulty display, or any other.

So, to help you solve this issue, the article provides all the essential information about the possible reasons that lead to the Lenovo ThinkPad black screen, effective methods to fix the issue. Moreover, it also offers a reliable way to recover data from a crashed system. Let"s get it!

As seen in many cases, one of the common causes of your Lenovo laptop"s black screen is related to hardware glitches in different components. Over time internal cables in your laptop wear out, and a damaged internal cable might cause the problem. Moreover, overheating your laptop might a graphic card crash, which would have corrupted your video display.

The faulty battery could also be a possible reason for your Lenovo Ideapad Black Screen. Unplug the charger from the battery source, and if your laptop suddenly goes blank, then it"s a battery issue. Try to replace your battery with a working one for confirmation.

Can a faulty battery cause a black screen? Yes, it could! If the power supply network has any issues, it might be responsible for Lenovo ThinkPad black screen issue.

You might wonder how power supply would lead to such a situation. Issues with the power supply can make your Lenovo’s screen turn black, which can cause quite a lot of problems for you.

As mentioned earlier, even when Lenovo laptop black screen seems like a huge issue, it is not. Only if you know various aspects of the issue will you be able to solve the problem. Here are the nine effective methods that can resolve the problem.

Most of the time, the black screen is only a minor glitch that your laptop witnesses. It happens when the Windows operating system loses its connection to the screen display. The following instructions will help you reset the display mode whenever this kind of issue occurs.

This will reset the connections, and the Windows OS may regain the display. Once done, check if it works, and you could see the normal display on your Lenovo laptop. If the above method doesn"t solve your problem, move to the next option.

If the previous method for resetting the display doesn"t work, it could be a display issue. To test if your laptop screen is faulty, you need a monitor and HDMI DVI or a VGA cable compatible with your laptop. Follow the instructions below to check the display,

Step 3: Now, click on the "Fn" key and "CRT/LCD" tab (either F5 or F8). Keep on clicking on it until the content of your laptop is displayed on the external monitor.

Just like non-peripheral devices, peripheral devices can also result in your Lenovo ThinkPad black screen issue. Have you noticed some dots spinning in the boot-up process? If yes, then you should do a hard reset on your laptop to check it. The following steps will guide you to do so.

If your Lenovo laptop boots up properly, it was one of the peripheral devices causing your Lenovo laptop"s black screen. Now, connect all your peripheral devices one by one until you reproduce the black screen again. This way, you will know which device was causing the issue.

They said it wasn"t applicable. Screen repair is screen repair last time I checked. Welp. Got my phone fixed. Whatevs."

Your ThinkPad is equipped with one or more external display connectors, VGA (all models), DisplayPort (T420s) and Mini DisplayPort (T430s, X1 Carbon), so that you may connect to an external monitor or the classroom multimedia projector.  You can connect to the external display by:Connect your external display to the appropriate connector on the ThinkPad.

If you turn your Lenovo laptop on and hear the computer working, but the screen is black, don"t panic. There could be a way to fix the Lenovo laptop"s black screen without replacing it or the computer.

If your Lenovo laptop has a black screen, there are a few things you can try to get it going again. Try these steps, each in order, until you find the solution that works.

Try a hard reset. In this instance, a hard reset is similar to a power cycle. Turn your Lenovo laptop off, unplug from any power, and remove the battery; disconnect any peripherals, and let everything sit for 30 seconds to a minute.

Connect to an external monitor. To test your LCD and LCD cables, connect your laptop to an external monitor with a VGA cable or connect to a TV as an external display using an HDMI cable, depending on the connections available on your system. Then restart your computer.

If the computer displays on the external monitor, the LCD or internal LCD cable could be faulty. Replace the LCD cable. If that doesn"t work, the LCD screen needs to be replaced and should probably go to the repair shop since replacing the monitor can be delicate. Do follow the steps below before taking on this repair to be sure it"s not anything else.

If you"ve tried everything above and the screen on your Lenovo laptop still isn"t working, there is likely a problem with the internal cables connecting the screen to the computer board or the display. Unless you"re well versed in repairing computers, then it might be time to call a professional. Just remember, if your computer is still under warranty, reach out to Lenovo first.

The ThinkPad X1 Carbon is a great laptop overall, while the Lenovo Yoga 9i is one of the best 2-in-1s on the market. Gamers on a budget should check out the Legion Y545, and people looking for a good Chromebook might like Lenovo"s Duet line.

Since Lenovo laptops run Windows 10, you can use the keyboard shortcut Windows+Print Scrn to take a screenshot. This copies an image of the screen to your clipboard. You then need to paste it into a photo editing program like Microsoft Paint or Photoshop to turn it into a .JPG or .PNG.

The Lenovo ThinkPad T420 is a 14-inch powerhouse that offers exceptional performance at an affordable price. This laptop comes with a decent amount of ports and an exceptional keyboard. However, it lacks USB 3.0 and HDMI ports, and also its touchpad is a little too small for a 14-inch laptop.

Are you searching for a laptop that is both affordable and capable of handling all of your daily computing tasks? If yes, this Lenovo ThinkPad T420 review might just be what you are looking for!

To familiarize you with the Lenovo ThinkPad T420, I’ll go through its features and specifications in this review. I’ll also go over the laptop’s design, processor, RAM, graphics, storage, and battery life performances.

ThinkPad T series laptops from Lenovo have long been the most impressive models on the business laptop market. This is due to their exceptional build quality, powerful performance, and outstanding keyboards.

The Lenovo ThinkPad T420 continues this distinguished legacy. The laptop features a powerful Core i7 processor, a durable build quality, and a very pleasant keyboard.

In addition to its exceptional features, this laptop is also affordable. At the time I wrote this review in August 2021, the ThinkPad T420 starts at a price of $195.00.

The ThinkPad T420 maintains the original ThinkPad appearance that business users have grown to appreciate over time. Furthermore, the ThinkPad T420’s design appears to be very similar to that of its predecessor, the T410.

The entire exterior of the ThinkPad T420 is made of plastic but in matte black. This matte plastic is more scratch-resistant than glossy plastic, and it also resists fingerprints and dust.

The chassis of the Lenovo ThinkPad T420 is quite durable and strong – ThinkPad T-series laptops have strong internal frameworks that reduce flex. This is beneficial to the internal circuit boards; the less they flex, the safer.

In terms of the laptop’s display, the T420 has a 14-inch screen that features an anti-glare coating. Additionally, the laptop’s display also comes in two resolutions.

The ThinkPad T420 comes with a 7-row, spill-resistant keyboard with a full range of keys. On the keyboard, even infrequently used keys like scroll lock and pause are available.

On each side of the ThinkPad T420’s keyboard, there are two stereo speakers. This set of speakers are adequate for watching video clips, but they lack the power and bass needed to enjoy music.

The T420 features both a Touchpad and a TrackPoint, just like other ThinkPad laptops. By hitting the F8 and FN keys together, you can disable and enable the touchpad and TrackPoint individually.

Due to the fact that the ThinkPad T420 features both a TrackPoint and touchpad, it has two sets of mouse buttons. The mouse buttons have decent key travel and provide just the right amount of feedback.

Moving on, the ThinkPad T420 has a lot of ports, however, a number of key ones are missing. An Express Card 34 slot, DVD/CD-RW combo drive, 5-in-1 memory card reader, USB 2.0 port, and USB 2.0/eSATA port are located on the right side.

USB 3.0 ports and HDMI ports are totally lacking from the ThinkPad T420. These are particularly regrettable omissions given that Lenovo offers USB 3.0 and HDMI on several other ThinkPad laptops.

Lenovo packed the ThinkPad T420 with the basic range of ThinkVantage utilities. The ThinkVantage Power Manager is one of them, and it allows you to control the laptop’s power profile.

Access Connections, which manages your wireless connections, is also one of the ThinkVantage utilities. The T420 also features Corel DVD Movie Factory, which may be used to burn discs.

Moving on, the ThinkPad T420’s dimensions and weight are 340.5 x 233 x 30.1 and 2240 g, respectively. Comparatively, the ThinkPad T420 weighs more than Toshiba’s Tecra R840.

Specifically, the Toshiba Tecra R840 measures 340.36 x 238.76 x 27.94 mm and weighs 2086.52 g. On a bright note, the ThinkPad T420 is lighter than its predecessor, as well as the Dell Latitude E6420.

Overall, the Thinkpad T420 is a durable laptop with an excellent keyboard and a good number of ports. Therefore, for its overall design, I will rate it an eight out of ten.

The Lenovo Thinkpad T420 comes with a 2nd Gen 4-core Intel Core i7-2620M processor. This Core i7 processor is based on Intel’s Sandy Bridge architecture and features a cache of 4 MB.

Additionally, the processor has a base frequency of 2.70 GHz and a maximum frequency of 3.40 GHz. With this processor, the T420 is capable of handling numerous computing tasks such as web browsing, photo-editing, as well as multitasking.

To determine the performance of the ThinkPad T420 with this Core i7 processor, I conducted a wPrime processor benchmark test. The wPrime is a multi-threaded benchmark tool that uses Newton’s method of estimation to evaluate a computer’s processing performance.

The estimated runtime required to calculate the processor’s hyper-threading ability is the result of the test – a shorter runtime indicates better performance. According to the results of the test, the ThinkPad T420 recorded a runtime of 16.65 seconds.

Comparatively, the HP EliteBook 8560p achieved a runtime of 15.79 seconds. Therefore, the HP EliteBook 8560p has a better performance compared to the ThinkPad T420.

However, in comparison with its predecessor (ThinkPad T410), the ThinkPad T420 performed better. On the wPrime processor benchmark test, the ThinkPad T410 recorded a runtime of 16.82 seconds.

Finally, the Lenovo Thinkpad T420’s processing performance is impressive, especially considering that it surpassed its predecessor in the benchmark test. However, it was unable to outperform one of its closest competitors on the same benchmark test.

In terms of memory, Lenovo equips the ThinkPad T420 with two 1333 MHz SO-DIMM RAM slots. These RAM slots support a maximum memory capacity of 4 GB RAM each – 8 GB altogether.

Moving on, I conducted a PCMark Vantage benchmark test to measure the overall performance of the ThinkPad T420. Based on the PCMark Vantage test results, the ThinkPad T420 achieved a score of 8,122 points.

Unfortunately, this score isn’t enough to beat the Dell Latitude E6420 score of 9220 points. However, the ThinkPad T420 performed better than its fellow ThinkPad model, the ThinkPad T420s which scored 6197 points.

In conclusion, the Thinkpad T420’s maximum memory capacity is relatively poor and it also underperforms when compared to its competitors. Therefore, I will rate the T420 a seven in this memory review section.

The 7200 RPM SATA HDD storage option supports a maximum storage of 500 GB while the SSD supports up to 128 GB. Moreover, the ThinkPad T420 also comes with a 5-in-1 media card reader for extra storage expansion.

The ThinkPad T420 laptop I reviewed shipped with a 7200 RPM SATA HDD which has a storage capacity of 500 GB. To assess the performance of the laptop’s HDD storage, I conducted a CrystalDiskMark benchmark test.

CrystalDiskMark is a benchmarking software for analyzing a computer’s storage drive’s speed and overall performance. According to the results of the CrystalDiskMark benchmark test, the ThinkPad T420 has a sequential read speed of 94.39 MB/s.

To further assess the ThinkPad T420’s performance with the HDD storage, I conducted a file transfer test. On the file transfer test, it took the laptop 3 minutes and 5 seconds to copy 4.97GB of multimedia files.

For graphics, the ThinkPad T420 comes with two graphics card options. The laptop is available either with an integrated Intel HD Graphics 3000, or NVIDIA NVS 4200M.

Therefore, when using the graphics card on the T420, don’t expect it to run graphics-demanding applications or games smoothly. On the bright note, the NVIDIA NVS 4200M features a dedicated VRAM of 1 GB DDR3.

The ThinkPad T420 laptop I reviewed came with both the integrated Intel HD Graphics 3000, and NVIDIA NVS 4200M. So, I conducted a 3DMark 06 test on the laptop to determine the overall performance of the graphics cards.

Based on the results of the 3DMark 06 test, the ThinkPad T420 scored 5,583 points. Comparatively, the ThinkPad T420 achieved a better score than the Dell Latitude E6420 and HP EliteBook 8460p.

I also conducted a real-world gaming test on the laptop to further assess the performance of its graphics cards. The ThinkPad T420 isn’t a gaming laptop, but its graphics card with dedicated VRAM is strong enough to play some popular title games.

For instance, the ThinkPad T420 achieved a solid frame rate of 61 fps when playing World of Warcraft. This frame rate is higher than the Dell Latitude E6420’s 41 fps.

Finally, despite the fact that the ThinkPad T420 isn’t for gaming nevertheless, it can play a few popular games. Therefore, I will rate the laptop an eight for its exceptional graphics performance.

For battery, the ThinkPad T420 comes with two battery configurations. The laptop is available with a 6-cell, 57 Whr Li-ion or 9-cell, 94 Whr Li-Ion battery.

Comparatively, the HP EliteBook 8460p lasted 6 hours while the Toshiba Tecra R840 lasted 6 hours and 34 minutes. Therefore, the ThinkPad T420 has a better battery runtime than both laptops.

Finally, I will rate the ThinkPad T420 a nine out of ten for its impressive battery performance. This rating is based on the 9-cell battery performance.

The Lenovo ThinkPad T420 is a well-built 14-inch business laptop that offers a lot at a good price. It features the ThinkPad trademarks of excellent build quality and a good keyboard.

Almost everything about the ThinkPad T420 appeals to me, from its long battery life to its numerous graphics options. Its touchpad, on the other hand, is a little too small, and it lacks a USB 3.0 port, which is a major flaw.
