So I've been asked to take a look at an old Advent 3001 laptop which was reported to randomly turn itself off, unusable for more than a few minutes at a time. Indeed, when I first took a look at it, it wouldn't even turn on. I've found that if I turn the laptop on its side, sometimes I can hear power start to flow and it does turn on, but as soon as I move it the power drops again. So clearly it's a mechanical fault.
I firstly noticed that the power cable was slightly damaged, so I replaced the power cable assuming it was a loose connection. Of course the battery should have kept it on, but it was a very old laptop and assumed the battery had died. However, replacing it changed nothing. I then replaced the power jack including the cable that ran to the motherboard, but that has also made no difference. With the new power cable and power jack, I can still (as above) get it to very occasionally flow power through when I turn it on its side, but there has been no noticeable improvement.
I am basically at the point of giving up now, as it is my assumption that the problem probably lies in the motherboard itself, and thus it would be better at this stage to just get a new laptop. But thought as a last ditch effort I'd post on here in case anyone has any ideas?
Thanks in advance.
