Having problems with your HP Pavilion dv6000z Notebook ?

HP laptop display issue

\015 My HP Pavilion dv6045nr will not show any display when booted up. Screen remains completely black, not just dim. Error code is 1 long beep, followed by two short beeps. Information I've found elsewhere indicates that may be a problem with the RAM, but I've tried replacing it and it had no effect. It has two RAM slots and I've tried swapping the cards, as well as running off one at a time. Basically i covered every possible combination of RAM placement, but got the same error every time. It was working one night with no indications of trouble, but a few hours later when I woke up it seemed that it would not "wake up." When I tried rebooting, I got the error beeps and it hasn't had a display since. I have NOT tried an external monitor yet, I would have to find someone with a desktop and don't know anyone off hand. I appreciate any help anyone can give! HP 9628nr\015\012Will boot to external monitor. Then works after reboot to laptop display. I have checked:\015\012Display Driver Nvidia 7150/M nforce 630M\015\012RAM\015\012LCD connections - motherboard\015\012Power management settings (Sleep hibernate OFF)\015\012Power adapter\015\012PheonixBIOS ver F.08 (f.32 avalable)\015\012\015\012After it appears fixed, (booting with external VGA monitor and then rebooting to laptop diplay) I power down for 2 hours, go to reboot and black laptop screen while I hear windows booting...\015\012\015\012There is a BIOS flash update but I really am not sure if it will help.\015

Answers :

If you are recving 1 long and two short beeps, it is not a memory problem.
\015\012It is not a Lid closing or lid switch problem.
\015\012If you are able to switch to and from your LCD and Monitor, you are lucky.
\015\012I have been up and down the road with several HP DV6000 series units, all have had the 1 long and 2 shot beeps.
\015\012HP is aware of this problem and has offered an extended 1 year from date of original warranty expiration. Another words 2 years from date of purchase. HP will ask for $365.00 + or - ? for this repair.
\015\012Their repair consists of a motherboard replacement.
\015\012
\015\012If you go to HP's web site, you can look up your model and if in warranty, have it sent back for repair.
\015\012The problem will not get better in time but only worsen. The heat sink on the dual core units is not handling the heat transfer properly.
\015\012The board is a 2 sided wafer which has displayed failure in several places, due to the heat load and transfer design. Area of problem is directly under NVIDIA chip look for craters. Theses are solder points the size of a pins head which because of the heat and the stress of the transfer bracket above, have separated making in some cases an intermittent connection to chip.
\015\012The best thing to do is have a technician remove the board from inspection and blow out the heat sink and surrounding areas.
\015\012Apply new heat sink tape and grease where needed and re-assemble.
\015\012
\015\012You must update your BIOS ver. to current.
\015\012This new version will address the Voltage and Fan Control Speeds in a better manor.
\015\012If your unit is just now giving you these errors, now is the time to act.
\015\012Just like in a A/C unit at home, a restricted air flow will make unit run longer and hotter.
\015\012Their are no filters here, once lint and dust have collected in the coils, it is just a matter of time.
\015\012Hope this helps you in your problems.
\015\012Anybody reading this note having a DV6000 series unit, should check at their web site for warranty and call back issues.

\015\012P.S. if you are a technician and feel you want to repair the board yourself, drop me an email with the model number and I will explain in more detail.
Try taking out battery and plug in power. If it works, battery is faulty. If not,
Try taking out your hard disk plug in power, if it works, hard disk is faulty. If not,
Try taking out memory card, if there's a sound, memory card faulty. If no sound, it's your motherboard that is causing the error.

Note: If machine is under warranty no need to pay for the repairs.

I have a fairly new HP dv5-1000US and the screen is almost constantly scrambling. It's almost like a vertical hold issue; kind of hard to describe. After the last few months, its gotten intollerable.
