Lenovo ThinkPad X220 Brightness Keys stopped working after Hibernate

I found that the brightness key of the Lenovo ThinkPad X220 failed to function when that resumes from the hibernate. It looks to happen more frequently while the power source changes as hibernated. Are there some other Lenovo ThinkPad X220 users who are having the same problem? Thank you so much in advance for replying to this post.

You can try to boot to the safe mode and once you have started the computer in the safe mode then just uninstall the GPU driver. Before doing that, you must download the X220 GPU driver first and then uninstall the GPU driver. Once you are done with that then you can reboot your computer to the normal Windows mode and see if you are getting the same issue again.

Just contact to Lenovo support to have better solution of this issue.

The ThinkPad X220 Lenovo is an ultraportable by means of a fresh format. It skins a 12.5-inch slab, showing a sharpness of 1366 x 768 pixels promising an extra contented working a 13.3-inch devoid of compromising its "mobility". Equipped with additional influential components, this configuration is supposed to be adaptable. The ThinkPad X220 is not what one may call a machine design. She is not unattractive, but its angular lines have not anything of the sweetness of a smoothed frame.

The "Lenovo ThinkPad X220 (NYG36GE)" is a perfect jump between work and leisure equipment notebook. The second-generation Intel processor provides unbelievable power and is just as economical in power consumption. Hardware technology, it is served really well and can take on any task. Thanks to the herrforagenden Lenovo batteries to extend the working range can be almost anywhere and you can test a whole according to its own working day without recharging get it over with.

The business companion par excellence is standard equipment in many companies, with sales representatives, offices and of course with ambitious private users. But the current X220 Lenovo has alone awakened by the available IPS display a lot of greed. This particularly pleased with those who suffer for years for lack of alternatives under low contrast and viewing angle-dependent displays. But the other principle available components such as Intel Core i7 CPU 2620m, USB 3.0, internal UMTS, mSata SSD or promised a term of up to 23 hours allow many hearts beat faster. But miracles cannot accomplish the ThinkPad X220. All together, you get unfortunately not given in a single unit and thus requires some compromise of the prospective tenant. One would have to decide between an internal UMTS module and an mSata SSD. USB 3.0 offer only the Core i7 models and the low weight of 1.3 kg cannot be combined with the longest possible battery life.

This Tablet PC packs a 12.5-inch 1366 x 768 IPS multi-touch screen, Intel HD graphics card, up to 8 GB of RAM, up to 320 GB HDD or 160 GB SSD, HD 720P webcam, an SD card reader, WiMAX, 3G (optional), WiFi, and USB 3.0 port, a 6-cell battery and runs on Windows 7 OS.

The touchpad is run at X220 without a separate keyboard and accepts clicks on the whole surface. This is achieved at the lower end, where you would normally expect the best and most appropriate buttons at the top of the worst. Usual basic functions go well, multi-finger gestures are more difficult to implement and do not enjoy here. Unfavorable turns out after some time the use of forward pulled down over the edge . Here one wanders in writing and passing the ball of your hand over it frequently, and thus unintentionally moves the cursor. Inveterate TrackPoint users interested in the rather less, since usually the same throughout the touchpad is turned off. With the "red bump" can be used to navigate precisely and associated keys work fine.

The ThinkPad X220 is Intel's latest generation Sandy Bridge is used, which delivers versus the former models a saturated power increase. The base offers Intel's QM67 chipset, which can currently take up 2 slots with up to 8 GB of DDR3 RAM. 1 RAM slot is the test model with a 4 - GB module fitted, the second slot is free. So the upgrade to 8 GB is a breeze. This is recommended anyway, since it can be used only with the second bar of RAM dual-channel mode.

This is realized at the more level closure, where you could typically anticipate the finest and most suitable catches at the top of the most dreadful. Standard essential capacities go well, multi-finger signals are more troublesome to enable and try not to get a charge out of here. Unfavorable produces some time the utilization of forward pulled down over the edge . Here one meanders in composing and passing the wad of your hand over it as often as possible, and subsequently unintentionally moves the cursor.
