Lenovo Essential G560 Troubleshooting
This troubleshooting page will help you diagnose problems with the Lenovo G560.
Computer Will Not Power On
The laptop will not respond or show any sign of powering up.
Faulty Power Adapter
Ensure the power adapter is plugged in and the charge light is on. If the light is not on, and the adapter is plugged in, the adapter is faulty. Consider purchasing a replacement adapter.
lllin, and the light on the adapter is on, make sure the adapter is connect to the laptop. If the laptop only powers up when the adapter is plugged in, regardless of charging time, then the battery is faulty. Replace the battery using this guide.
Keyboard/Keys Not Responding
The keys on your keyboard won't respond or appear to be broken or missing.
If the entire keyboard fails to respond, try replacing it with this guide.
Keys Are Stuck In Place
When keys can't be pressed, there may be something below the physical key holding it up. To fix this, remove the key and make sure nothing is stuck below it. You may need to wipe off the area underneath. Once it is sufficiently clean, snap the key back into position.
Keys Are Missing
If keys on the keyboard are missing, replace them.
Computer Won't Boot
Your computer does not load the Operating System and instead takes you to an error message.
Not Enough RAM
If your computer crashes during normal operation, crashes during memory intensive tasks, or beeps and will not boot up, this means you have bad RAM or that you do not have enough RAM. Install RAM into your computer.
Hard Drive Error
Even though you have a hard drive in your computer, there may be an error on it. This can happen when the user shuts off the computer by pressing the power button instead of initiating the shutdown sequence through the operating system. To resolve this issue, get a Windows DVD for the version that you have. Please note that the specific version does not matter, only that it is for Windows XP, Vista, 7, or 8. Boot to the DVD, and choose “Repair your computer,” then click next. On this screen, pick “Startup Repair” and let it run. After this, your Lenovo Essential G560 should boot correctly. If your computer does not boot correctly and still has issues, you may need to replace your hard drive.
Audio is Distorted
You have trouble listening to sounds on your computer.
Loose Headphone Jack
Test audio through the computer speakers, then test it using headphones. If the audio is only distorted while listening via headphones, the audio jack or the headphones themselves may be faulty. Audio that cuts in and out is often a sign of a loose audio jack, so make sure the audio jack is fully inserted in the computer.
If the audio sound is distorted when listening through the laptop’s speakers, the audio driver may be corrupt. Search for Lenovo G560. Click “Lenovo G560 Notebook,” then click “Drivers & Software.” Click the “Audio” tab and select and download the appropriate driver. Go to Control Panel -> Device Manager -> Sound Controllers. Click on your sound card and click “Update driver.” Select your updated driver, then restart the computer.
Failure to Read CD's and DVD's
Your Lenovo G560 will not read any CD's or DVD's.
Broken/Defective Optical Drive
If your Lenovo G560 optical drive does not open or does not read CD's or DVD's, the optical drive may be broken and needs to be replaced.
The monitor on your Lenovo G560 doesn’t show anything, and you know the computer is turned on.
Make sure that the display is not accidentally disabled. To do this, press one of the “Fn” keys in the lower corner of the keyboard and then press “F2.” If the display was disabled by accident, then this will re-enable the display.
If the above action does not fix the problem, repeat the previous instruction once more, hold down the Windows key, and then push “P” twice. The computer may have been previously set to “Projector mode;” doing the action above will convert it back to “Computer Only.”
Video is Distorted
Video image is distorted, blurry, or discolored.
The computer may be operating in an incorrect resolution. To fix this, double check the Resolution settings by right-clicking the desktop, and selecting “Screen Resolution.” The ideal resolution for the Lenovo G560 is 1366 x 768. Alternatively, it is possible to change the resolution by pushing the “Fn” button and then hitting “F4.” This should bring up a small menu where you can select the correct resolution.
Outdated Video Driver
If certain videos flicker, appear blurry, or change to incorrect colors, the most probable cause for this issue is an outdated video driver. To update the video driver, go to this site and download the appropriate video driver by checking for the correct operating system.
Device is Overheating
While you are working, your computer randomly shuts off without notification.
Dust in Vents or Fans
Computers can overheat due to excessive dust and other materials stuck in the vents or fan. To fix this, use a compressed air duster to carefully blow the dust off the vents and fan.
Inadequate Amount of Thermal Paste
Your computer may not have adequate contact between the heat sink and processor. This is usually caused by a lack of thermal paste or by air in between the two components. To fix this, completely clean off any old thermal paste, then apply a bead of new thermal paste directly in the center of the processor. Gently push the heat sink back in place and tighten screws to lock down the heat sink.
