I recently received a used Toshiba Tecra 9000 from my brother. It has several problems, but I'm only bothered by one. I"ll list all the problems though.
1(the one that bothers me). I've been using Ubuntu Live to test/operate the computer, but recently (last two days) it has started freezing while loading the OS.
If I pull out the AC power supply, partially remove the battery, or tap on the corner of the laptop over the battery, it will sometimes start loading for a few seconds.
I have taken down, and re-assembled it a few times, and I'm pretty sure I got all the connections nice and tight.
2. The computer will not detect a hardrive in the port. I can run it off of a flashdrive though, so it's not a big problem
3. The built-in mouse, and keyboard occasionally do not respond.
I've worked on computers for a few years, so I don't think the problem was caused by mis-handling.
