Question about HP Pavilion dv4000 Notebook

1 Answer

Battery/configuration/ Hi, I have had this hp pavilion dv 4000 for 2 years (bought it new) and I noticed that If I disconect the mains from the laptop, the screen goes blank, but the pc stays on. If I connect the mains back, the image doesn't come back, so I have to switch the pc on and re-start it. If I start the pc without mains, just running from the battery, it shows the boot up process, the logo of windows, but then stays black and doesn't start up as normally does In the 2 years I didn't use much the baterry, so I really wonder what is wrong? thanks

Re: battery/configuration/


My name is Vikram Kumar Thumu, from India-Hyderabad. I have seen your message on the issue . I would like to provide my suggestions on the issue. I hope that this should work for you and will resolve the issue.

well, the issue seems to be with Battery , it is not working properly any more. or it could be an issue with Battery drivers in PC.

To isolate the issue, I recommend you to try below steps. This will resolve the issue .

Step 1: Connect Battery and Also AC power adapter, try to charge the Battery for around 6 hours. Make sure that notebook is idle for 6 hours, do not try to run any application . Just let notebook be ON for 6 hours with AC power with Battery in, so that battery gets charged up.

Step 2 : Once if you are done with 6 hours of Charge, now disconnect the AC Power. Restart PC and let the PC run on Battery only. Check out how much time PC is able to run on battery. If PC powers ON properly with battery and runs around 40 minutes then it confirms that Battery is fine else if PC do not startup properly or if it works less than around 30 minutes on battery then it confirms that it is an issue with Battery. If found fault with battery then try step 3 process.

Step 3 :  To check Health of Battery

Please open below link in the new Internet Explorer. Copy and Paste the link at the address bar  and then click GO. This will open a web page that titles as " HP Notebook PCs -  Checking the Status of the Battery in Windows XP"

Link :

Once if you open web page, please perform the steps that are mentioned in web page as appropriate to your issue. I hope that this should resolve the issue.

If you need any further assistance on the issue, please mail me at I'll be glad to help you.

HP DV600 laptop doesn't turn on even on mains.

It sounds like your ac adapter has died, and thus is not charging the battery back up. Test the adapter for power output. If it isn't working, the only option is to purchase another.
