U510 touchpad & keyboard stop Working!

2014-06-25, 2:26 AM

i bought u510 since 2 months .... and it worked perfectly until last week
when i opened the laptop the touchpad doesn't work and when i restart the system it works again and some times lag
and i thought The reason for this is the driver!
from two days ago touchpad stop working at all even in SafeMode and device manager doesn't show any mouse connected to the lap ! 
after it keyboard became laggy and stop working too
i turned off the computer and discharge battary and hold the power button for 10 sec
and open it and every thing worked perfectly like nothing happened before
afteri finished my work i turned the computer off and open it after 6hours | same problem happened again
and now some times touchpad not working at all or work for while and stop and keyboard became laggy and refuse to type some times ....
i'm certain it's not software problem
now what i have to do to fix this problem ?!

Hi Mpchell,


Welcome to Lenovo Community!


I’m sorry to hear that the Touchpad and Keyboard is not working as expected even after performing all the possible troubleshooting steps. Hence, the only available option to check if the issue is hardware related is by performing OSRI (Operating System Re-Install) using OKR (One Key Recovery).


NOTE: Please backup the data in the computer before performing OSRI, as the data will be completely erased.


If the issue persists, I would strongly suggest you to contact our Technical Support for further Assistance to get the details of the nearest Authorized Service Center to get the issue analyzed.


Click here to open a link where you can select the country and get the exact contact support number. I’m sure they will be a great help.


Do post us back for further queries.


Best Regards

Shiva Kumar
