HP net book has a white 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)

Sounds like you have two hot wires. Just need to find out which wire goes to the wall switch. Try gray to black from fan,pink to black/white wire.white to white & green to green. If this doesn't work swich the pink & gray wires.

whoo hooooh a full model number but no OS stated
CQ60-615DX
i guess all users of PC are clueless what the OS is or its name.
vista or w7? (click control panel then system , bingo OS) name)

no photos posted of this black screen box. nor when it happens.?
I see HP dropped all software support now, but yes some guides still there. 2008? year? LT?
so HP does drop support in10 years, they even say that.


the BUG battery main is long ago bad and shorted, keep the battery out for ever, or buy a new one. end big battery facts, keep it out.
now run on AC ? power ok, only (wall power!)
then get a new coin cell battery HP RTC stated in the service manual . the manual to do that is missing now.
HP is trimming off line books on this pc.as we type.
2008 is the worst year for any laptop, the solder ball years from hell.
but if the PC runs ok mostly (you never once said tHAT)
The its not bad nvida chip inside. (causes full black screens or lines)
but these guys to. see page 4-12 actual = RTC coin
page 51 in PDF. covers the coin cell swap out.
$2 part for sure bad at 10years old 7 is par.
this book was deleted at HP, (bums)

The screen is faulty or the screen cable has become dislodged. Best take it to a repair shop.

since the machine has been setting for 20 years, it needs to be serviced
the old grease & oil have probably turned the gunk. the servicing can also tell if any parts are damaged

Hello,

I suspect on teh wiring from the house the black&white will be the hot wires and the bare will be ground/neutral

use a volt meter before connecting tonew cooktop and check for;
black/bare to have 120volts
white/bare to have 120volts

if that is what you find...connect new cooktop as such;

black to black
red to (house) white

(cooktop) white and green to bare

I have bought a new 32GB Rizone mp4 player from ebay & I used it only three days. Now screen shows white lines. you can see video of that,


I am very upset & Extreamly warning to every one not to buy!

please contact your dealer for repair or replacement. most monitors are covered by atleast 1 year warranty. usually 2-3 years.

Check your connecting cables to the monitor. They can become loose or you may have a cracked cable.

Hi, from the sounds of your situation, im sorry to tell you that your address book is gone. If you have hotsync with your desktop before, you may be able to retrieve a copy of your address book from your last sync. Otherwise there are companies available to recover data from pdas but their services are very expensive.
