HP DV928US When battery in or charger plugged in
fails battery out so leave it out they love to short.
so when it fails test 2 is, hit the F10 or ESC key promptee
went it fails to boot, check BIOS key first, if BIOS fails.
be more clear.
what does it do when it wont turn on.
BIOS dead. screen 100% dead, and not even text
BIOS works even with HDD and DVD drive pulled.
that is the acid test on PCs.
the screen must say, hit F10? or ESC to enter setup, means HP BIOS. it must or power is no good. get a new power pack
the shut down tell me lost power, that can be the power pack 19vdc
or the jack at the mobo if failing to said pack.
try side pressure on that jack if at anytime the power button fails.
it self shuts down, I got that but lets fix , cant boot first.
that is how to fix this.
power on failures, are you saying the power key fails. some times
and the fan does not run every time.?
this old LT uses CCFL back lamps.
that love to fail. so when it shut down did the fan die.
did the HDD stop spinning ear to bottom? if not the CCFL is failing.
using and external monitor proves this every time,
do the flash light trick?
