Hp Pavilion dv6 sudden, complete power loss during use

During use this computer suddenly lost all power. Was running on it's proven functional power supply. When I plug power supply in the light adjacent to plug lights up...however, when the battery is depleted a "lightning bolt" icon should light up to indicate the battery is receiving power...this does not happen. Computer is absolutely dead. I have checked power supply...it is good. I have a dv7 that uses same power supply...trying this yields no results. I don't know how to check a battery with multimeter. Does power to motherboard need to pass through a "good" battery in this model?? I'm stumped. Really appreciate your help. Doc2526

SOURCE: HP Pavilion dv2500 no display when power lights not blinking

Hello

To get the display on the TV . Please press Fn + F4 after connected TV to the Notebook using Svideo cable and the cable should be connected to the Svideo port of the Notebook.

If there is not display on the Notebook after the Svideo cable burns.
Then please perform the following steps.

= Power Drain =

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter and Battery.
5. Turn on the Notebook power.

If the issue persists then check whether the display is same on the external monitor.

I hope this will work.

Thanks

SOURCE: HP Pavilion dv4000 battery won't charge

all you really need to do to find out if it might be broken is to check and see if that DC Jack on the computer is "wiggling" around, if the center part is moving around. If it is, then there is a chance that it is broken. I used to work at a computer store where the owner would resolder new DC power Jacks into laptops, but he was the only one in town who did that. So you might want to check around at the local computer repair or electronics stores to see if someone does that type of thing. Also, have the power supply checked out, it could just be dead.

The laptop's AC power jack is probably damaged. All you have to do is put the fork aside :D, unsolder the old power jack and solder the new one in. If you are not good at soldering you can get it done by a qualified professional. Its a 5 minute Job and a pretty inexpensive repair.

Regards,
Sai.

SOURCE: hp pavilion dv8000 help

I had the EXACT same issue on my HP Pavilion DV8000. After reading this thread I started disecting the machine, sure the issue was a faulty internal power plug/cable. It is TRULY a big job, but very doable without special tools. You pretty much have to take every single screw out of the thing to get to that stupid cable.

Here are a few things to know:
1) there are a lot of screws - mainly long black (L 12) and short silver (L 5x2.5). Keep track of all of them in order so you don't end up like me - with 3 leftovers. Lol. There is ONE long black screw that is a little shorted than the others (L 10). This is one I had left over. There are two VERY tiny black ones. I also have one of those left over. There is also a few smaller black ones, too. Just keep them all noted as you remove them and remember where these odd ones go!
2) There are some very flat band cables that plug in to tiny plgs. However thereis no plug on the cable. The flat end just shuves into the plugs. These are very delicate. be gentle with them.
3) When you finally get the housing for the fan loose you can now get to the entire power supply cable. Here is a note: I FIXED my problem by unplugging this cable and plugging it back in. The cable runs under the fan housing, and it seems like you have to remove that housing to get to the cable, but actually it comes out again right next to the processor and heat sink. There is a thin sheet of black sticky insulator tape over the processor and the cable at that point. You'll have to gently remove it. There is not much room there, but you CAN unplug the cable without removing the entire fan housing.

Here is what I did to test this plug and cable. After unplugging it, I shoved a tiny straightened staple (the female plug is very tiny) into the female receptacles for the prongs on the motherboard (red and black only). Then I plugged the power supply in to the power jack. With a DC meter I verified that the female end of the power cable inside the machine was getting juice, and it was.

With nothing left to test, I put it all back together (save three screws) and it is now charging the battery and running from the ad power plug. Whatever I did fixed it!

One last note: There are 4 sequenced screws that hold the heat sink tight. These are under a bit of pressure so the sink is tight. DO NOT remove these as the sink has a heat conducting "goo" that helps it disperse the processor heat. As old as these machines are now, you don't really want to disrupt that "goo" and risk the processor over heating.

I hope all of this typing helps someone.

I have a HP Pavilion dv6-3120us Entertainment Notebook. A update came from HP for the BIOS and while installing the update, it will not finish. Its frozen at 100% can you assist?


your options are wait for it to complete. Or power cycle it and hops it froze on downloading, and not during installing.

Manually download the bios update yourself and then flash it manually if it does come back up.


If the computer fails to boot up then you will need to use a recovery bootdisc and then to apply the bios update again manually as opposed to doing it in windows.

My hp pavilion dv6-1030us is all of a sudden not booting up. It turns on fine but when it comes to the loading screen that says Microsoft Corporation and has the loading bars running across the bottom it...


try going into safe mode F5. reboot and keep tapping F5 if you can get into safe mode try a system restore back to the time it was working. if not reload from recovery drive (F11 i think) or from recovery disc.
hope this helps.

91 900s Looses power, won't run through puddles/sudden power loss


Check all battery terminals and 12v power feed connections are clean and tight.
Check all battery chassis and ground connections are also firm and in good order.
Check any in line 'Maxi' fuse connections are firm.
Check for water ingress in any cable loom or bulkhead connector exposed to the water spray.

Hi! computer help pls!


You need to run the recovery discs that you received with or burned after you first got your computer. Some computers have it built in and you can access it by hitting the key that it tells you during boot up to run a system recovery, often F10 if its an HP or Compaq.

For solving blue screen error


HP Notebook PCs - "Windows Unsafe or Sudden Shutdown" Blue Screen Error Occurs During Startup or Boot

Description
Windows XP may not start and the following error message may appear on a blue screen:
Windows Unsafe or Sudden Shutdown
This error occurs after Windows was not shutdown using a safe method. The notebook may have been turned off without clicking Shut Down or briefly pressing the computers Power button. The power may have been suddenly disconnected from the computer or the Power button may have been held for more than 5 seconds.
An unsafe shutdown can damage some of the Windows system files, preventing the computer from starting properly.
Solution
If the error occurs allow the operating system to complete a check of the hard disk. Windows will prompt your to run CHKDSK. CHKDSK scans the hard drive for damaged files and repairs the files if necessary. The scan may take up to an hour depending on the size of the hard drive and the number of damaged files. The computer will restart when the scan is complete and Windows should start normally.
If Windows will not start or the computer will not boot after the scan is complete see: HP Notebook PCs - Troubleshooting a Startup or No Boot Problem (In English)
