Re: z400 TOUCHSCREEN PROBLEM?

hi lisheng,

 

Welcome to Lenovo Community Forums!

 

First Try doing a Power Drain.

 

Then Open Device Manager and open the Human Interface Devices

  Uninstall all that starts with HID- then restart the system See if the problem will go away

 

If still the same I would consider this as a hardware Issue

 

You can contact Lenovo Technical Support here

Best Regards

Solid Cruver

Re: z400 TOUCHSCREEN PROBLEM?

I bring my lenovo z400 to lenovo shop here in Philippines but what happened is my laptop's brightness function keys are not working, brightness not working always on low and the screen got smaller in size. I just say what they have done is this what warranty looks like. it sucks totally sucks. and the repairmen says that the LCD is defective my gawd

Re: z400 TOUCHSCREEN PROBLEM?

i'm experiencing same problem with the same unit, i thought the problem was with the lcd screen as the repairmen told as, my unit was still under warranty they sent it back to lenovo for repair... the dealer told me that the status was an lcd is on delivery for replacement, only to find that it was some kind of a z400 touchscreen sickness... hope lenovo will find a way for this problem and redeem themselves.... im looking forward for a replacement of other unit... it is so frustrating that whole unit becomes useless due some screen problem... almost perfect...

Yes, Until now my Laptop is not fixed. Lenovo can't repair it. at first only LCD is the problem then it got even worst after the replacement of LCD. its been three months since the repair and i still can't have my laptop. it still broken. worst laptop brand ever. if i would buy another one it won't be lenovo.
