you forgot to say the SCREEN IS DEAD and BLACK on no text ever shows up there, nor do BIOS screens work (even with HDD removed)
mine has 3billion transistors , any of which bad can kill it dead.
we dont guess we
do tests.
called diagnostic testing, or go broke guessing. see?
leave the battery out for now, batteries can and do short often.
next is the power pack 19vdc, good, 10v bad we test that using a magic tool called a
voltmeter ($20 in stores, DMM)
i have 100 solutions (i pass) or just 3.
1: bad power pack; battery out.
2: bad mobo (we can tests here all day ,wana? asK)
3 : dead screen, does the external jack vga work to external monitors?
is this a PC 2008 with the horrid solder ball problems.????

solder balls.
