if you know a bit about electricity, please help

I think I may have a bad lithium battery - the one under the keyboard, not the removable one, that one was really expensive and is really good - but I've done some research and.. I get this error when I start my computer on battery power - no AC "WARNING: system checksum bad" - and that seems to imply a bad internal battery.. so.. hmm dunno :/ I'm kinda broke right now, if that's an expensive repair..

 

Electricity comes from other planets...

 

it's your bios battery, that's the bios checksum.

the checksum is a certain process by which a "checksum" is derived, if it matches, it's good, if it doesn't, it's bad, that sometimes happens when you whack the bios battery, which if you want to try to change it yourself, is probably a three dollar battery at MOST, the labor would be a pain in the ass because it's a laptop.

 

Yea my BIOS has been fucked-up for about a year anyways.. I don't know what to do, it's been like that since I added RAM.. I tried to flash it but.. didn't seem to help..

My laptop is in a pretty bad shape right now. There's this AC adapter problem, and my LCD is cracked, I have this huge white thing blocking my view on the bottom right of my screen, plus these lines.. and there's the BIOS.. and it constantly overheats, too.. the fan works but.. sometimes I'm in the middle of doing something and it just shuts down on me..

I am praying (well not really but you get my point) so that my hard-drive doesn't suffer anything.

 

take out the harddrive and copy it to another computer?

 

I am planning on getting an external hard-drive this week before I attempt any more repair on my laptop, just to have a copy of all my music at least somewhere.. since I have no more cds.. I think I'd probably commit suicide if I lost my music..

 

there is a usb dongle that will plug into laptop, ide, and SATA harddrives, and let you treat them like external harddrives via the usb port, I've seen them around. but can't think of anywhere in particular that has them.

 

oopsie. I dunno Ac theory yet. sorry ma bad.
