On Toshiba's it's probably not the problem keeping it from booting.:nono: They will still boot from default settings stored in the BIOS--CMOS battery only stores date/time and other custom non-default settings that you changed.
Try this: remove the laptop battery, ALL RAM sticks (usually 1 or 2 in laptops), and the Hard Drive, and disconnect the external monitor.
Use only MAINS power also known here as the AC charger **no battery**, and attempt to power on the laptop. You should receive a series of audible
"beeps"; we tekkies call this audible
"beep-codes" which are diagnostic codes built into all laptops at the factory for Technician troubleshooting and repair.
If this test fails to produce
"beep-codes", then almost certainly the Motherboard is bricked and will need to be replaced.
This is $175-$400 in the US; 2-3 times that cost outside the US. :ermm:
As with most of our users, they are embarrassed by getting a defective laptop from a friend, and so we don't get details. When you say
"got", did he
GIFT it to you for Free, or did you pay him
CASH MONEY??? If you paid him, he sold you a bill of bad goods!:facepalm: If he gave it to you, and this is quite common, he already knew it was bricked, and probably knows
EXACTLY what the repair cost is, and so instead of throwing it in his trash, he
GAVE it to you or
SOLD it to you (
even worse!).
Either way, he did you no favor.
:nonono:
