My question: What diagnostic tests can I conduct to find the problem. If it's the mainboard then I'll have to replace, but maybe it is something worth fixing.
Update: after a few minutes it did start up with a balck screen saying : Warning Resume Failure. It is working again for the moment but I want to know what the problem is, if/when it might reoccur and how to fix it.
It starts quite intermittently, more off than on.
I recently added a reg key : DWORD - IPRStackSize which reenabled my network. Seems unlikely to be related though. However there are all kinds of messages going off in systems event viewer. I could post a log of this if it helps.
I've had success starting it up by removing AC power, thus initiating startup off the battery (which is 4 years old like the computer and pretty much stuffed) and then re- plugging in AC power.
However a new battery costs way too much from Toshiba...
I'm eyeing up a couple of broken lapotops on a local auction site to salvage for parts, but first I need to find what is wrong...
How can I go about diagnosing the problem?
Any help is appreciated greatly
