battery will not charge
I am using a 1 year old HP laptop running W7 home premium. As of
yesterday I noticed that when I am plugged in and hover my mouse of the battery icon it says I am "plugged in-not charging". I can find no setting where I may have inadvertently switched off battery charging. Finally I discovered that if I remove the battery and immediately put it back in I get "plugged in-charging". The battery charges fully and runs over 2 hours which is about normal for it. What concerns me is that I still get the "plugged in-not charging" when I plug power in after the battery has run low and again this is resolved by removing and re-inserting the battery. Not usre if this is a battery problem or a problem with the charging circuitry. I ran the command powercfg -energy -output c:\energy-report.html and got (among other things): Battery:Battery Information Battery ID Hewlett-PackardPrimary Manufacturer Hewlett-Packard Serial Number Chemistry LION Long Term 1 Design Capacity 47520 Last Full Charge 42163 Any advice? Thanks, Jeff |

Any advice? If you have a warranty, then send the laptop in to be checked out. |

I cleaned the battery contacts and it's now back to working correctly. So I'll keep my fingers crossed and my eye on it especially since it is out of warranty. Will also check out the above link. |

Thanks, Jeff It is a flaw in windows which is easily corrected. 1) leave windows operating. 2) pull out the battery 3) unplug the power. 4) install the battery. 5) plug in the power. 6) restart windows. you may have to do this a second time. Thanks. I had read on the web that there was a problem with Windows 7 and power management that affects battery charging - which is why I asked on this forum. See: http://forums.cnet.com/7723-19681_102-345945.html So far so good so I am keeping my fingers crossed hoping the problem does not return. :=) Will keep you message in case I need it. |

With Li Batteries If the battery voltage is too low, the battery minder may prevent charging.Basically,one side of the battery is disconnected from the usual output connection by the battery minder. The reset/recovery method I last used was to connect a DVM to (across) the battery output lead that was switched off and the battery minder leads that went to the actual battery output lead. This was after recharging the battery to the nominal voltage via the "real" battery output leads. |
