I have a Toshiba Tecra A9 stuck on the splash screen after my intervention in the bios to boot from a USB stick.
At the start, it turns more on the startup screen with the 5 symbol of choice (hard disk, USB, etc.).
Clicking on a symbol and nothing responds I can not enter the bios.
It is displayed at the top of the screen: In Touch With Tomorrow TOSHIBA and five symbols.
I disconnected two small green battery on the motherboard for 10 minutes, but nothing has changed.
That said, I do not know if I disconnected the battery good (y 'have it two?).
It also would it make a metal button battery on the motherboard?
If the notebook cannot pass the Toshiba Splash Screen then this means that the POST (power on self test) cannot be passed properly… and this means mostly than an hardware part on the motherboard or the motherboard itself is faulty…
That’s worst case since the mobo is very expensive…
