ACER blank screen

11 years old today this PC.
we have answered this same question here vast times.
ever search, sure nobody does, nor googles.
it's laptop, I have many like it.
first do the long reset ? did you off the HP.com site?
long power on reset.
remove AC pack.
hold power button for 10 -30 seconds,
the release the button.
put back AC pack now, both ends.
power on, fixed?
no.
next drop the huge battery off the bottom , the one that is 10 years old, is now shorted.
now AC pack reconnected both ends, PC runs now"
even text to the screen or the HP logo graphic is PC is not dead.

now when you turn it on the BIOS must work or the coin cell battery RTC battery tiny is dead. (under keyboard it is)
HP has nice service manual, unlike most makers.
Dell and HP haver the best books in the business.
(support books (docs) PDF's
RTC coin cell is 2.9vdc or higher, less is bad.
using any voltmeter ever made.(LV) we use a DDM for $20

page 73 = RTC COIN STEPS.

THE OTHER BAD NEWS:
is all 6930s have nasty CCFL back lamps
that are all dead now. (if used 8 hr/day ) every day.
some die at 5 years old not 11 like yours.
with the PC turned on and you think screens are there.
bios screen or windows login screen.
then do the flash light test. if data is there, now the CCFL tubes are dead (1 or 2 parts bad inside)

hi

First of all if you can remove the ram memory DO IT SO ifyou cant try without removing FIRST.

-remove battery pack(if you can romove memory ram aswell) and wait 10 mins
-now start charging laptop without battery pack for 2 mins
-unplUg the power AND press and hold the power button for 45 seconds
-REPLUG THE POWER CABLE BUT DONT PUT THE BATTERY PACK YET

NOW OPEN THE LID WIDER YOU CAN PRESS POWER BUTTON YOU WILL SEE YOUR SYSTEM WILLSTART ONCE YOUR SYSTEM BE READY SHUT IT DOWN PUT THE BATTERY PACK BACK ANDCONTUNUE TO USE YOUR LAPTOP

When a computer does not boot up, but the battery is charging, it could be a CPU or RAM problem.
Re-seat the RAM modules, this will make sure it makes proper connection to the motherboard.
Next try removing the battery and power up the laptop with just the power adapter connected. If it boots up then insert the battery while it is powered up.

Try upluging it, remove the battery, then press and hold the power button for 10 full slow seconds. Then wait 1 minute, put battery back in, plug back in and turn on.
It should now come on and work fine.

vote me if you find your solution

remove battery, press and hold power button for 5 seconds, then put battery back in and start.
This usually works. If by slight chance it does not, check that the memory cards aren't loose or faulty.

do a hard reset....remove charger>remove peripherals>remove battery> press and hold the power button for about 30secs, while batt and charger is removed> then plug in the charger only and turn ON!

Please vote, thanks!

try without the battery connected

do a power reset on the computer. turn off the computer. remove the battery pack and unplug the ac adapter. press and hold the power button for 10 secs without any power source to drain all excess power in the laptop. put in the battery first followed by the ac adapter. turn the computer.

i hope this helps.
