800x480 display blocked

Hello,

My Aspire is blocked in 800x480 resolution.
This resolution appears from the bios.
How to revert to 1024x600 resolution?

Sorry for poor english

 

What are you running? XP or LinPlus?

 

I installed Ubuntu 8.04.
The problem became clear at that time.
I returned to Linpus but remains in 800x480 resolution.

 

Did you reinstall LinPlus with the recovery DVD?

 

Yes, i reinstall Linpus from recovery DVD but the resolution remains to 800x480

 

I removed the battery but it stays the same.

ye, when I add the Ram in , it happens. Not to sure which part on the board is can not read the drivers. Use the recovery usb fix it.

 

Mine did just that after I added ram... Had to put it all apart again and unplug /replug the screen a few times, then it worked fine again.

 

You unplug /replug when you are in bios or Linpus ?

 

I think he means unplug literally, i.e. take the cable out and put it back in again...

Yep... it's a hardware problem.
The funny thing is the same thing happened to my normal laptop some years ago, an HP, the screen did the same thing suddenly and I sent it back. Now the guys at HP didn't just replug it correctly, the changed the whole screen, in fact they put a 14" screen in place of my 15"4 screen, oh, with the wrong screen frame color too (silver instead of black, and even with another laptop model sticker on it). When they finally sent it back with a 15.4" screen it was a crappier one than the original one. Thanks HP...

 

begs the question, 'how are hp the #1 in the world'

 

Make sure your LCD panel ribbon (like) cable not to across the yellow square capacitor located below the screen connector. I had a similar case before and found that the heating of the capacitor seemed to affect the signal transmission of a part of the Panel Cable.
