New Laptop Battery not Charging

Hi,

I have an HP Pavilion DV4000 laptop which recently experienced problems with the battery - the old battery would charge to 100% but if unplugged would go down to 0% within minutes.

I assumed a new battery was required - ordered one and fitted it, the laptop worked fine with the 50%-odd charge that the battery came with, but it wouldn't charge - it just says 'plugged in, not charging', and there is no charging light on the front of the laptop.

If I put the old battery back in, it charges fine, and the charging light comes on - I therefore assumed it was a dud battery as there was no apparent problem with the power lead.

I sent the new battery back and got another one - same thing happens, no charging.

Seems unlikely that I have two dud batteries (from two separate suppliers). There are no power settings in the BIOS that I can change, and nothing seems wrong with the control panel settings for Power Options.

Has anyone got any ideas?

Thanks

Consider this thread at HP Forums Calica and although what is stated may not solve your issue you will at least have a better insight as to the issue.

Thanks for that info - I read the HP forum and it's good to know I'm not alone!

Perhaps the only difference is that in all the examples the users could get no charging light to illuminate. I can get the light to illuminate if I plug in the old battery.

I suspect I'll end up just using it on the mains with the old battery, and send the new one back for refund, if I can!

Cheers

Running it from the mains would be the best bet.

How old is the laptop by the way?

HP had loads of issues in the past with the DV range of laptops regarding batteries so as I said earlier mate just run it off the mains.

Just come across this topic which reminded of similar incident some weeks ago and I finally found an answer (outside the forum) which I will pass on in case it helps. 

 

Go into Control Panel, Device manager and expand Batteries.  Look for Microsoft ACPI-Complaint Control Method Battery. Right click and Uninstall(If there is more than one with the exact same label do the same  but leave Microsoft AC Adapter alone). (You may see a restart window but ignore for the moment). Still in Device manager go up to the Taskbar and click on Action and select Scan for hardware changes.  This is usually over in seconds and likely there is no message. Now you need to restart and when Windows opens the battery -previously showing 0% or not charging or cannot locate battery - should should signs of charging.  Slowly at first but quite soon the 0% changes to 1% and should continue until fully charged.  That is assuming the battery is up to it, but otherwise this was the only thing that worked for me and has been fine since.   I did this on an old Dell latitude D630 that had previously been used plugged into the Adapter which reported that it could not find a battery.  I tried everything and even bought a new battery and nothing worked until I came across this remedy.
