Tecra failure



Hi all

My daughter brought home from Cyprus her poorly Tosh' Tecra 8100 after
having all er data removed to a desktop there by a "professional" in
Cyprus...The laptop was working OK then, apart from occassional screen loss.
I am unable to boot to floppy(except if I use F12..ready for bios update
feature).
When I boot up without battery connected, there are 2 green lights
showing...power & screen.Screen not showing anything..except the F12 above.
The CD lamp lights up momentarily on startup, but unable to access it.
The processor fan is NOT turning...(disconnected, cleaned & reseated).
Removed single RAM module from bay A...cleaned and replaced.
HD(12gig) removed, cleaned contacts & refitted.
Inverter removed & refitted to ensure connected OK.
I have hooked up to my desktop monitor with no screen display.
I am unable to access the bios with several keyboard
combinations..Esc,F1,FN,F5,F8, etc.
Tried to search Google etc. but unable to satisfy my desire to bring it
"back to life".
I am unable to check out electrical components with avo etc....suspect CMOS
battery??..it is connected OK though, as is the fan connecter.
I do not wish to take it into repair shop as it is not worth what their
charges may be I suspect.
Any other questions / suggestionsI will try to answer/try.
The last resort is to sell it for spares/repair?

TIA

Terry
