Problem: X220 Blank screen + Mute LED

2012-06-17, 13:49 PM

Hi,

 

Ive got a problem with my X220: From time to time, the screen goes blank and the mute key LEDs turns on.

Its still working, I can start audio playback via hotkey etc, I just dont see anything.

The only chance of getting the screen back to work is to press the mute key.

 

This is pretty annoying even it only occurs every few hours. It doesn seem to be related to any certain program, sometimes it occures while gaming sometimes while having the x220 idle on desktop.

 

I tried reinstalling Windows 7 and changing the drivers. No improvement so far.

 

Any ideas?

Could be a hardware issue, but before you go the "call Lenovo" route try updating the bios to the latest version 1.29.

 

Good luck.

I have exactly the same issue.  Just began within the last couple of weeks.  I have updated the bios.

 

It is very infrequent and also seems unrelated to computer activity or particular programs running.  x220 is still alive, but blank screen.  I couldn't get it to wake up, so put it to sleep and then back on and it returns to normal.

Try booting into the BIOS and rock the LCD and see if the screen will go blank intermittently?

Leave laptop in BIOS will have this issue?

Mine will also do this periodically while plugged in.

 

My solution is to unplug it from the back, and plug it back in, then the screen comes back on and the mute light goes out.

I solved my problem :smileyhappy:

I had recently changed the laptop memory putting in it two ramaxel 4GBx2. Since then the problem appeared. First I did not correlate it to the ram change, but clearly now after i inserted back the default samsung 2GBx2 rams, the problem disappeared completely.

The ramaxel rams that I have used are 1600MHZ, not the supported 1333mhz , so I'm pretty sure this is a problem of incompatibility.

I'm not sure if this is related, but I know that Lenovo, from Bios version 1.29 and above, forces a 1333mhz ram frequency.

I think that I do not need more than 4GB, at least under my Archlinux, my swap space is almost always free. With the msata drive, the laptop is fantastic.
