I'm attempting to repair a Toshiba satellite pro a300 for a friend. When you turn it on all you hear, is the processor fan spinning up and optical drive testing but nothing else no hdd drive activity, no POST, just a black laptop screen.
Initially, the fan will spin up and drive test once but if you turn it off by holding the power button down approx 10 seconds and turn it back on, the fan will stay on.
As a had a spare broken laptop of the model, laying around that I knew everything worked on apart from a BIOS bug that would ask for a start-up password that had been randomly generated by the system itself, is no hope getting past that. So as you can imagine, I haven't much faith in the laptop models reliability.
I've tried with no success.:sad:
- new memory modules
- new hard drive
- a complete laptop strip down, checking all connections
- stripping the laptop monitor to check the video connector
- replacing the original laptop monitor, to rule out back-light burnout or a bad GPU.
I'm no Noob, but this one has got me, at a loss:confused: and the only conclusion, I can draw is yet another MB has gone south, doesn't say much for Toshiba
