The things is I want to sell my laptop after, so I don't want to rip it apart, I'am not that technical as well to do all that, I just don't know why it's playing up like this, do I have to do something with he hard drive before I transfer anything to it? I didn't say so in the manual.
If the battery is dying, and the DC port doesn't work, you'll have to find some way of getting your stuff off, and wiping the drive.
Take the drive out (it should be easy) and plug it into something else.
And if the battery doesn't last long enough to copy a 1GB file, it certainly won't last long enough to install a new OS.
If you are selling it, I wouldn't give you 50 quid for such a dead machine.
Actually, now that I look at the specs
, you'd have to pay me to take it off your hands. It was a bottom of the barrel thing two years ago.
