Acer Travelmate p253-m bios

[cavallofurioso]

Hi everybody.
I have a travelmate p253-m that have a problem with the bios.
First, when I on it, it stuck on acer logo; F2 worked.
Tried the recovery procedure with Fn+Esc and usb (2Gb): it have read the usb, without any succes.
So I have tried to remove battery on motherboard and, from that moment, when I boot up che pc, it show me a black screen.
Altready tried with recovery method but with any success.


Can I have a help? 


Thanks you
