first screen died, now wont boot, to external VGA monitors.
Fn+F4, sure. the external command key. sure
ok VISTA, first time any one tells what OS is there, wow.
step one on all PCs lap or desk top is what,
does the screen show any text at all?
like Hit Esc to enter setup or BIOS>
we first see of BIOS is alive. it not the PC is DEAD.
zero text means DEAD PC> and NO BIOS means DEAD PC
so out comes that old useless LT battery.
useless as in , if its original its bad. most are.
you skipped step 1 here, (battery out)
and next fans work? and blow air, no lint packups. inside.
learn that PC's go dead, with overheat, can happen fast.
