I believe this a hardware related issue and not a Ubuntu specific. take a lookThanks for the replies.
I had called up the ASUS support and they want to take the laptop back to check. As long as they can get the laptop back in a working condition I will be glad.
I have been using Ubuntu for long now (even though am just a novice) I have had problems with losing grub or screwing up my partition but as long as the system started up I was able to use a spare PC and get to the forum to make it work.. but this one is dead as dead.
Any reason what could have caused this - was it the battery, bios not being up to date or ...
Some info on my installation:
1) I had a dual-boot with win 7 and did not remove the asus back up/recovery partition.
2) I have not updated the BIOS because when i tried to locate the files on the usb drive, system reported those files were older than what was installed (the files were named with some numbers like 201 or 209.. instead of dates!)
3) I did not use the script modification advised on the ubuntu site for asus to help from suspend/hibernation. I tend to power down the ux31 when it is not in use.
4) I used the scripts to make the touchpad respond to right clicks and use it as a clickpad (using xinput to find the id for the elantech touchpad thingy and use it as input parameter for the scripts i downloaded)
all of this was working fine until yesterday.. I did not make any other changes except agreeing to install the patches and the laptop was running on battery that time (I did not notice it to be that low it was pretty well charged)
Is there any way I can boot in to a USB (live-usb) and run some commands and post the output here to see what could have possibly gone wrong? (before I could pack this off to the support) may be it would give the developers some info on what caused the crash?
