A client has a SONY VGC-V2M all-in-one PC. It is like a fat TV – a P4 based motherboard in a black case with built-in LCD, DVD, and all the usual sockets.
If it halts on a LCD FAN hardware error then the computer is still usable until you can investigate further. At the American Megatrends BIOS POST then do the following sequence to get Windows booted,
F2 to get to BIOS ESC to exit from bios it will ask to discard or not <return or enter> to pick the OK to discard
now Windows will continue to boot. Now is obviously the time to make sure your backups are up to date !
As an aside it is actually easy to upgrade the memory in this all-in-one. You slide the back up a few inches until it catches and then it sort of pops off by moving it back away from the case. How it latches is some locking tabs that fit through gates into a slide so you have to slide the back up until the tabs are aligned at the gates and then it easily pops off backwards. Don’t force it.
The memory is under the metal panel on the right hand side (looking from the back). Motherboard has two slots and AFAIK it is 1 GB max of DDR PC3200 400 Mhz CL3 or similar per slot. You probably have 512 MB fitted and running Windows XP so for routine Office use just fit another 512 MB for the cheapest upgrade as Windows XP is now unusable rubbish on only 512 MB but fine on 1GB. Maximum is 2 GB in total i.e. 1GB+1GB.
