    Hi,

    My Toshiba Satellite P50 laptop is 3 year old and no longer boots.
    "Toshiba Leading Innovation" logo is displayed continuously, Windows is not called and there's no beep (I don't remember if there was a beep when it worked).

    Keyboard, mouse pad and fan are working.
    No USB device is connected.
    I can enter the UEFI BIOS and configure it.
    I then removed all useless drivers: USB 3, camera, etc...
    Inside, no dust, nothing unplugged, and nothing burnt.
    I cannot see a speaker, this may explain why no beep...

    I removed the battery --> stuck at the same logo
    I removed the DVD player and the hard disk --> stuck at the same logo
    I tried to boot from a Windows and Linux USB key (without secure boot etc...) --> stuck at the same logo
    I can read the hard disk content from another computer.
    I unplugged the CR2032 --> I have to enter the date then stuck at the same logo
    I removed both 4GB RAM --> it stops before the logo (OK then)
    I tried all RAM combinations into both slots --> stuck at the same logo

    I don't know how to get a proper diagnostic.
    Any idea?

    Sounds like the BIOS has become corrupted. Try removing the battery and holding power for 2 minutes, to drain the eeprom cache. Try to boot again with JUST THE POWER PLUG, NO BATTERY.

    Thanks.
    Tried that (even 5mn instead of 2) but no change: the Toshiba logo appears immediately and stays forever.

    Try downloading the BIOS file from the Toshiba website onto a USB or cd/dvd. Then you said you can access the bios, right? Try installing that bios file onto the system to see if that fixes the issue.

    Well, unless I'm wrong, the Toshiba BIOS can only be installed from Windows.
    Inside the BIOS menu there's no option to install another BIOS, and no option to run diagnostics...

    No the BIOS can be installed from the BIOS itself but only on SOME OEM systems.

    Unfortunately not the case for my Toshiba laptop.

    I found these directions. Since nothing else has worked, it might be worth a try.

    What's the full model name ? Probably be on a label underneath and something like P50-PSPNSx.

    Tell us that and we can find the correct Bios which can probably be installed from a bootable CD.

    I've already downloaded the latest Toshiba BIOS.
    The problem is that I cannot boot from the hard disk, I cannot boot from a bootable CD, I cannot boot from a bootable USB stick. (boot mode set to CSM)
    The DVD LED blinks or the USB stick LED also blinks when powered on: They are recognized during the very first steps of the startup, but I think the issue is that it doesn't even try to start the OS, from any drive. It's stuck before this step.
    So I cannot load the latest BIOS.
