Hp pavilion dv5 blank screen with two blinking lights.

check by removing the battery then put it back again power it on, or without battery power it on directly then check, if still the same problem, the fault is in the motherboard of the laptop, better take it the service center or consult some technician in your area

no photos of white screen presented or posted.
is it white in a dark room???????????

lacking any photos , it be impossible to fix this talking in text box.
no?
as they say ,seeing is believing, what you call white I call black.
white on sunny beach, or black in dark room, can be the same.
PAvilion dv5-1125nr

always post what a pC does in the dark, its best.
all text seen , all logos seen (hp or compaq)
any boot screens, any log in screens.
and if the "hit F10 key to enter HP setup" is missing on said screen as seen now for 9 years running.
if that text is missing,
remove the big battery in rear of LP,they short, so get it out now
and first., do that first. always,,,
then run on AC power,
do the HP long reset? (battery out, ac pack pulled
push power button 10 to 30second, not use the ac pack only
it can run on AC forever, end ever , no problems.
do so now.
got that that 9 year old text now? in the dark, ok?
The F10 is BIOS hot key, power on and quickly hammer F10
bingo for BIOS. see that? see those screens, those are first.
if BIOS is dead, it can not boot any OS made.
BIOS does the booting job, see?

Hi

what colour is the screen please
can you hear the laptop working
or do you think that it has switched itself off then

please also tell us what operating system you are running and is it the original factory fitted os


many thanks

Shut down the computer.
Turn on the computer tapping F10 key on your keyboard.
You will see BIOS comming up.
Go to the option SMART and Run HDD Self Test.
If it passes then get another set of recovery disk for HP Pavilion.
If test fails, replace hard drive.

i got the solution to this problem, watch the vid i made for all of everyone to use for the solution.

This unit should still be in warranty. If out of the first year warranty, HP has extended the warranty program for Video issues for a extra year from date of purchase.
Register your unit with HP, if not already and email customer care and log your video issue, ASAP.
I hope this has helped you.

Check your power management settings. Reset to suit your usage. This should fix it.
