History
My laptop Hard disk had failed segments after it hibernated due to power outage, I decided to backup whats left then decided to visit the BIOS to make sure it boots from USB.
F2 instead of sending me to the Bios screen had the laptop go into F8 menu instead...
I booted into safe mode, took a backup on an external drive. rebooted but this time Hitting F2 resulted in LOUD BEEPS !!!
I rebooted & it ran fine after this so I decided to first to keep it unplugged (Maybe my mistake to remove battery & outlet since bios was bit rotting?) then buy another HDD to replace the old one.
After 16 hours of no electricity I plug everything Aaaand Darkness
Tried the usual of replacing RAM etc...
ITS A NO POST from here on out.
Even caps lock is not reacting...

Having doubted the firmware behavior I decided to search the Toshiba website (last visited in 2018) to be surprised it became Dynabook!!!
The official Bios in Dynabook website is version 2.40 bb10240.fd CRC 3B8A1F6B for Satellite L630/L635 models having part numbers beginning with "PSK00U"
For some reason also in the download section of L655 ???
I highly doubt it is the right one since there are i3 variants without AMD ATi GPU out there!
while my laptop is an:
Intel Core i5-450M Processor
ATI Mobility Radeon HD 5145
I am gonna search for Tech shop that has An ISP programmer but first,

Here are some NOOB questions:
1_ Is there a way to know the Motherboard model without disassembling?

2_ Can the already existing bios (downloaded from the support page) work on my motherboard model?

3_ What is the chipset for my processor?
Searching the forum I found a modded bios for CPUID 20655 but it is for i5 460?

4_ If I found a bios for the motherboard but has the wrong chipset, cant it be modded?

Glad to learn something new & Thanks In Advance
