dead PC,
this failure and all cures have been posted here 100s of times.
even 1000 times. ive done 1500 now dead pc's.
- what are you asking, ?
- how to fix it
- or what's wrong from morbid curiosity?
- or want to learn how to fix PC,
- or who can (any PC repair shop on earth, yes)
- id bet no store fixes 11 year old PC, store? repair shops sure.
the book on your PC shows it is
11 years old now. 2007 made.
most PC this old are dead an parked in an attic, most.
you skipped step 1. and is...
remove the dead shorted many battery, non last 11 years.
not one. (if im wrong we do a guinness world records interview)
lol
so remove it and see if it works now.
step 2 is the screen, all old PCs 2010 or older (most then all)
have CCFL lamps that all died long ago
and the screen is black forever now, all do that every one.
if USED every day.
if the screen never shows text ever ?
then the back lamp is dead. (battery out, AC pack connected)
yes> black.>
then we do the flash light test next,
if you see data now, then the CCFL are dead.
99% tubes bad or 1% inverter that runs them dead.
in 2010 this ended with LED, your PC is NOT LED.

if the flash light test fails, NO DATA there.
then 2007 PC had the solderball from H3LL failures.
GPU grapics chip from Nvidia are bad.
the kiss of ***** here the fix is 10x more that the PC is worth.
value dead is $5 this old.

and can cause all the above.
read page 44, its childs play fix.
