    Weird Startup Problem With Toshiba Laptop - Genius Diagnostician Needed

    I agree that your analysis makes sense, but booting after the power button has been depressed for a minute with all power sources removed (then added back) doesn't produce any change in behavior. Power light goes on, a short burst of a dsik spinning all in the first second or so and then silence...

    Weird Startup Problem With Toshiba Laptop - Genius Diagnostician Needed

    After a few days of finding something more rewarding to do, I took the unit to bits again, then reassembled, leaving the USB daughter board, speaker and mic connectors uncoupled, and I also removed the Wifi card and disconnected the CDROM drive. The unit booted fine. Then after switching off and...

    Weird Startup Problem With Toshiba Laptop - Genius Diagnostician Needed

    Interesting. I inserted a bootable CloudReady USB key (Chromium OS) and tried booting after leaving it overnight. It booted to this screen. I clicked f1 to resume and it booted the HDD (which was higher up the boot order) as it should. Then closing down and starting up again, it went straight to...

    Weird Startup Problem With Toshiba Laptop - Genius Diagnostician Needed

    Ah OK - no, I didn't use a USB keyboard. After I wrote that post, I removed the laptop keyboard and plugged in a USB keyboard but couldn't get anything to happen. At the moment, no matter what I do, the power light lights up, but absolutely nothing else happens. I can force a restart, and have...

    Weird Startup Problem With Toshiba Laptop - Genius Diagnostician Needed

    More developments: a) Swapped out memory modules - no change b) changed the HDD - it booted once. Then on reboot it displayed the same symptoms - nothing. No amount of Fn f5 and shift f8 reboot sequencing would help. I wondered if the issue is that there's been an unknown accident to the...

    Weird Startup Problem With Toshiba Laptop - Genius Diagnostician Needed

    I just swapped out the processor. It's made no difference: it still won't start. So in summary: - Refurbed mobo (and this means the BIOS is different as well) - New battery - swapped out SODIMMs - refurbed CPU - nothing out of the video port, and occasionally the screen springs into action as...

    Thanks - I have some answers below - will check out some further ideas prompted by your message. Also, I can get a replacement CPU for a few $ (it's so old) so will try that as well. And then it's probably the end of the road. When you state that is started as it should with Linux HDD in how...

    Weird Startup Problem With Toshiba Laptop - Genius Diagnostician Needed

    Well - I did take everything to bits again, cleaned the caddy and blew out the contacts, installed fresh thermal paste, swapped out the HDD for an old one with Debian installed and used a new stick of RAM. And it started up, as it should! Hurrah. So I powered down, swapped out the HDD for the...

    No, I didn't - sounds like I have some work to do.

    Weird Startup Problem With Toshiba Laptop - Genius Diagnostician Needed

    Fair question: the motivation is that this is an old laptop that my daughter stopped using and it just got pushed to the back of a cupboard. I think because it had some reliability issues but that was ages ago and I can't remember the details. Anyway now my elderly dad could do with a laptop...

    Weird Startup Problem With Toshiba Laptop - Genius Diagnostician Needed

    OK - will check, but if this MoBo wasn't made for my processor I can't see how I would have been able to get the BIOS to run. I was able to set the clock and restore the default settings at one point with the new MoBo. Then when everything was saved and I exited from BIOS, black screen again.

    Weird Startup Problem With Toshiba Laptop - Genius Diagnostician Needed

    Hmmm - I don't think so. It's an AMD processor, and the caddy just opens up when you turn the screw 180 deg - the CPU lifts out no tugging necessary. I dropped it back carefully, and no resistance felt when it dropped in. Then turn the locking screw and it was firmly in place. These problems...

    I did yes, and on the GPU as well.

    Weird Startup Problem With Toshiba Laptop - Genius Diagnostician Needed

    This concerns an old Tosh Satellite Pro L450D which was stuck at the back of a cupboard and I'm now trying to inject life into it again. When I first dusted it down and booted it (Win 7 installed), all went well no problems, but the following day when I tried again, I had the black screen of...
