Model upgrade. Despite its slim build, there is plenty of computing power in Lenovo"s gaming laptop. The combination of powerful hardware, 4K screen, and decent connectivity is to make potential buyers curious.

Lenovo offers relatively compact gaming laptops in a 15.6-inch size within its Y50-70 lineup. We previously tested various models from this range, and are now facing a new model that is equipped with a graphics core from Nvidia"s GeForce 900M lineup. To be precise, it is the GeForce GTX 960M. Our report reveals whether the new GPU has any advantages.

Since we have tested several models of the Y50-70, we will not go in-depth about casing, connectivity, input devices, screen or speakers. The corresponding information can be found in the reviews of the Lenovo Y50-70 and Lenovo Y50-70 (59424712).

1 USB 2.0, 2 USB 3.0 / 3.1 Gen1, 1 HDMI, 1 Kensington Lock, Audio Connections: headphone-out, microphone-in, Card Reader: SD, Sensors: brightness sensor

Speakers: 2 speakers + subwoofer, Keyboard: chiclet, Keyboard Light: yes, external DVD burner, Cyberlink Media Story, Cyberlink Power2Go 8, McAfee LiveSafe-Internet Security (trial), MS Office (trial), 24 Months Warranty

Since the Y50 does not have a maintenance cover, the casing has to be opened for maintaining/upgrading the hardware. Lenovo has complicated this matter unnecessarily. After all screws have been released from the bottom, the base unit"s tray comes off at three sides by itself. There are no clips. Solely the rear is not released. The fans" covers are part of the bottom tray. Since the tray could not be removed without effort, we did not make any further attempts in order to prevent damaging the casing.

We have previously tested a 4K model of the Y50-70. It features the same Samsung screen as in our present review sample. The rates differ slightly, which is normal. Two identically built screens will never correspond to one hundred percent. The installed Samsung screen can only serve with an average brightness and average contrast.

A review about the Full HD model of our present review sample will be published within the next few days. Basically, the 4K and the Full HD screen are identical. The latter has a higher contrast and lower brightness than the 4K screen.

Lenovo"s 15.6-inch Y50-70 gaming laptop has more than enough computing power for every day, and renders all up-to-date games smoothly. Our review sample is available for approximately 1500 Euros. Lenovo also has many other configurations. The currently lowest priced model from the lineup is sold for just below 800 Euros.

As in the previously tested models of Lenovo"s Y50, Intel"s Core i7 4710HQ (Haswell) quad-core processor is also inside our present review sample. It is a standard mobile processor with a TDP of 47 watts. It has more than enough computing power for all common application scenarios. The installed quad-core processor only provides a slight advantage over dual-core processors in single-thread performance, which is more important for routine use. It can first clearly distance itself in applications optimized for multiple cores.

The CPU operates at a base speed of 2.5 GHz, which can be boosted to 3.3 GHz (four cores), 3.4 GHz (two cores), and 3.5 GHz (one core) via Turbo. The CPU processes single-thread applications at full speed in AC mode. However, the laptop only exhibits the same behavior as its sister models in multi-thread applications, which are only processed at the base speed (2.5 GHz). Thus, the CPU clearly remains behind its potential in multi-thread applications. Laptops from the competition, such as Acer"s Aspire VN7-591G, do not have this problem. The Y50 shows a slightly different behavior in battery mode. The processor begins processing at 800 MHz, and gradually increases that up to 2.8 GHz only to suddenly drop to 800 MHz again. That is then repeated from the beginning.

The system runs smoothly, and we did not encounter any problems. The PCMark benchmark scores are good. However, the Y50 clearly lags behind comparable contenders, such as the Aspire VN7-591G, which also features a 4K screen. It becomes evident here that the processor in Lenovo"s laptop does not utilize its Turbo in the multi-thread tests. Both the Aspire and the Y50 generally score worse than its sister models that have a Full HD screen. When the desktop resolution of the 4K models is reduced to Full HD, the PCMark scores climb to a comparable level. The system performance of our review sample cannot be increased; Lenovo has utilized all possibilities.

The Y50 sports a solid state drive from Samsung. It is a 2.5-inch model with a capacity of 512 GB. The laptop"s owner can use approximately 410 GB of that. The remaining storage capacity is divided among the Windows installation, recovery partition and a partition for the Y50"s drivers and applications. The SSD can serve with overall good transfer rates.

The installed GeForce GTX 960M graphics core is an entry-level model from the GPU upper range. It clocks at a base rate of 1097 MHz, which can be increased to 1176 MHz via Turbo. The GPU"s maximum speed is only a few percent higher than that of the former GeForce GTX 860M graphics core. Since the cores only differ in speed, the 960 core only scores marginally better than its precursor in the 3DMark benchmark. However, the difference between the 960 and 860 models in the Y50 is greater than among the comparable models of Acer"s Aspire VN7-591G lineup. The reason: The GeForce GTX 860M GPUs in the Y50 models do not clock at their maximum possible speeds.

In addition to the GeForce core, Intel"s HD Graphics 4600 GPU has also found its way into the laptop. Both cores form a graphics switching solution (Optimus). Intel"s GPU is intended for routine and battery mode. The GeForce GPU is enabled in performance-driven applications, such as computer games. Switching is automatic, but the user can always intervene manually.

Lenovo"s Y50 is explicitly aimed at gamers. Thus, it is not surprising that it can render all current games smoothly. It is normally possible to select the Full HD resolution and high to very high quality settings. The resolution and/or quality level has to be reduced in some games, for example "The Witcher 3". The frame rates are only slightly higher than that of laptops equipped with a GeForce GTX 860M graphics core. However, the advantage over 860 models of the Y50 is greater, like in the 3DMark benchmarks, because the GeForce GTX 860M GPUs in the Y50 models do not clock at their maximum possible speeds.

The screen"s maximum resolution (3840 x 2160 pixels) can only be fully utilized in rare cases. This option is at most possible in games that only have moderate hardware requirements. The Y50 only achieves just below 70 fps in the benchmark of the game "Dirt Rally" in very low quality settings. The rates drop to 25.3 fps in medium and 22.8 fps in high settings.

It sometimes happens that the fans in the Y50 are inactive, and then not a noise is heard. However, the fans usually spin at a low speed. It should not be surprising that they speed up under load; after all, the laptop features high-performance hardware. We measured a noise level of 49.2 dB during the stress test, which is an acceptable rate in this performance category.

The Y50 performed the stress test (Prime95 and Furmark run for at least one hour) differently in AC and battery mode. The processor clocked at 2.5 GHz and the graphics core at 1085 MHz in AC mode. They were throttled to 1.4 to 1.5 GHz (CPU) and 836 (GPU) in battery mode. The laptop"s temperatures are acceptable in view of the hardware configuration. Several measuring points on the casing surpassed fifty degrees Celsius.

(-) The average temperature for the upper side under maximal load is 43.8 °C / 111 F, compared to the average of 33.8 °C / 93 F for the devices in the class Gaming.

(-) The maximum temperature on the upper side is 58.8 °C / 138 F, compared to the average of 40.4 °C / 105 F, ranging from 21.2 to 68.8 °C for the class Gaming.

The energy requirement reached up to 15.9 watts in idle mode - a very low rate for a high-performance gaming laptop. We normally measure rates of over 20 watts from the contenders. Lenovo appears to have the energy requirement well under control. The power consumption climbed up to 115.5 watts in the stress test. That is apparently too much for the 135 watt power supply because the battery was drained during the stress test. This problem did not occur in gaming routine; the laptop consumed approximately 100 watts in this scenario.

Currently we use the Metrahit Energy, a professional single phase power quality and energy measurement digital multimeter, for our measurements. Find out more about it here. All of our test methods can be found here.

The Y50 managed an idle runtime of 6:28 hours. It thus clearly outperforms its rival Acer Aspire VN7-591G (3:36 h). Idle mode is ascertained using Battery Eater"s Reader"s test. The screen is set to minimum brightness, the energy-savings profile is enabled, and the wireless modules are off. The Y50 shut down after 1:24 hours of load. The Aspire (0:58 h) is depleted sooner. The load runtime is checked with Battery Eater"s Classic test. The screen runs in maximum brightness, the high-performance profile and radio modules are enabled.

Lenovo"s laptop stopped our real-life Wi-Fi test after 3:23 hours. Again, the Aspire (2:46 h) lags behind. This test simulates the load induced when websites are opened. The "Balanced" profile is enabled, and the screen"s brightness is set to approximately 150 cd/m². We test the video playback time by running the short movie Big Buck Bunny (H.264 encoding, 1920 x 1080 pixels) in a loop. The wireless modules are disabled, and the screen"s brightness is set to approximately 150 cd/m². The Y50 lasted 3:27 hours. The Aspire (2:56 h) shut down earlier.

Lenovo is quite able to convert the relatively low idle energy requirement in decent battery runtimes for a gaming laptop. The contender Acer is outperformed here. The battery capacity of both laptops ais almost identical (Lenovo: 55 Wh, Acer: 52 Wh).

Lenovo"s Y50-70 59441231 is a 15.6-inch gaming laptop. The installed processor has more than enough computing power for all common application scenarios. The GeForce GTX 960M graphics core renders all current games smoothly. It also produces slightly higher frame rates than the GeForce GTX 860M precursor. It should not be surprising that the laptop reaches relatively high temperatures and produces noise in view of the hardware configuration. The installed 4K screen made a mixed impression. On the one hand, it is a viewing angle stable IPS screen, and on the other, its brightness and contrast could be better. It is rarely possible to use it in in games, and primarily boosts the purchase price. Like its direct contender Acer Aspire VN7-591G, the lack of a maintenance cover has to be criticized. The casing of both laptops has to be opened for replacing or installing a hard drive.All things considered, the present device can be filed under "model upgrade". The only real innovation is the GeForce GTX 960M graphics core. Owners of a laptop with the former GPU do not really have a reason for switching to a GTX 960M graphics core. The performance gain is marginal.

General safety Follow these rules below to ensure general safety: Observe a good housekeeping in the area where the machines are put during and after the maintenance. When lifting any heavy object: 1. Make sure that you can stand safely without slipping. 2. Distribute the weight of the object equally between your feet. 3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift it. 4. Lift it by standing or pushing up with your leg muscles; this action could avoid the strain from the muscles in your back. Do not attempt to lift any object that weighs more than 16 kg (35 lb) or that you think is too heavy for you. Do not perform any action that causes hazards to the customer, or that makes the machine unsafe. Before you start the machine, make sure that other service representatives and the customer are not in a hazardous position. Please remove covers and other parts in a safe place, away from all personnel, while you are servicing the machine. Keep your toolcase away from walk areas so that other people will not trip over it. Do not wear loose clothing that can be trapped in the moving parts of the machine. Make sure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it. Insert the ends of your necktie or scarf inside clothing or fasten it with the nonconductive clip, about 8 centimeters (3 inches) from the end. Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing. Attention: Metal objects are good electrical conductors. Wear safety glasses when you are hammering, drilling, soldering, cutting wire, attaching springs, using solvents, or working in any other conditions that may be hazardous to your eyes. After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective. Reinstall all covers correctly before returning the machine to the customer. Fan louvers on the machine help to prevent the overheating of internal components. Do not obstruct fan louvers or cover them with labels or stickers.

Important: Use only approved tools and test equipments. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents. Many customers have rubber floor mats near their machines that contain small conductive fibers to decrease electrostatic discharges. Do not use such kind of mat to protect yourself from electrical shock.

Find the room emergency power-off (EPO) switch, disconnecting switch or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly. Do not work alone under hazardous conditions or near the equipment that has hazardous voltages. Disconnect all power before: Performing a mechanical inspection Working near power supplies Removing or installing main units Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer to power-off the wall box that supplies power to the machine, and to lock the wall box in the off position. If you need to work on a machine that has exposed electrical circuits, observe the following precautions: Ensure that another person, familiar with the power-off controls, is near you. Attention: Another person must be there to switch off the power, if necessary. Use only one hand when working with powered-on electrical equipment; keep the other hand in your pocket or behind your back. Attention: An electrical shock can occur only when there is a complete circuit. By observing the above rule, you may prevent a current from passing through your body. When using testers, set the controls correctly and use the approved probe leads and accessories for that tester. Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as metal floor strips and machine frames. Observe the special safety precautions when you work with very high voltages; instructions for these precautions are in the safety sections of maintenance information. Be extremely careful when you measure the high voltages. Regularly inspect and maintain your electrical hand tools for safe operational condition. Do not use worn or broken tools and testers. Never assume that power has been disconnected from a circuit. First, check it to make sure that it has been powered off.

Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds. Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage. Do not service the following parts with the power on when they are removed from their normal operating places in a machine: Power supply units Pumps Blowers and fans Motor generators and similar units. (This practice ensures correct grounding of the units.) If an electrical accident occurs: Caution: do not become a victim yourself. Switch off the power. Send the victim to get medical aid.

Safety inspection guide The purpose of this inspection guide is to assist you in identifying potential unsafe conditions. As each machine was designed and built, required safety items were installed to protect users and service personnel from injury. This guide addresses only those items. You should use good judgment to identify potential safety hazards according to the attachment of non-Lenovo features or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.

Consider these conditions and the safety hazards they present: Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock) Explosive hazards, such as a damaged CRT face or a bulging capacitor Mechanical hazards, such as loose or missing hardware

To determine whether there are any potential unsafe conditions, use the following checklist at the beginning of every service task. Begin the checks with the power off, and the power cord disconnected.

Checklist: 1. Check exterior covers for damage (loose, broken, or sharp edges). 2. Turn off the computer. Disconnect the power cord. 3. Check the power cord for: a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and the frame ground. b. The power cord should be the type specified in the parts list. c. Insulation must not be frayed or worn. 4. Check for cracked or bulging batteries. 5. Remove the cover. 6. Check for any obvious non-Lenovo alterations. Use good judgment as to the safety of any non-Lenovo alterations. 7. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage. 8. Check for worn, frayed, or pinched cables. 9. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Handling devices that are sensitive to electrostatic discharge Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge.

Notes: 1. Use product-specific ESD procedures when they exceed the requirements noted here. 2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.

When handling ESD-sensitive parts: Keep the parts in protective packages until they are inserted into the product. Avoid contact with other people. Wear a grounded wrist strap against your skin to eliminate static on your body. Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap. Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices. Select a grounding system, such as those listed below, to provide protection that meets the specific service requirement.

Attach the ESD ground clip to any frame ground, ground braid, or green- wire ground. When working on a double-insulated or battery-operated system, use an ESD common ground or reference point. You can use coax or connector- outside shells on these systems. Use the round ground prong of the ac plug on ac-operated computers.

Grounding requirements Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
