HP Notebook PCs - Battery Not Detected. Battery—if the battery is still not detected. Upgraded from XP to Vista. To get the latest version of the HP.

Hi, I'm having issues with battery charging and my Windows 7. When booting, the battery is detected in BIOS and charging (charge light is glowing, not blinking). As soon as the computer boots off my HDD and Windows loads, the charge light starts to blink, indicating that the battery is not charging. In Windows, the battery meter displays 'no battery detected' or 'plugged in and not charging'. At first I thought my battery was simply getting old, but out of accident I forgot to plug the AC adapter in and the computer ran off the battery for ~1.5h, even though Windows didn't recognise a battery. This still applies, which I haven't found a solution to yet. I've tried running the hardware off another Win7 copy and the same thing happens.

I haven't had time to try Linux or WinXP yet, since I own neither. I've also tried uninstalling the ACPI Battery Control in the Device Manager, but without success. Any suggestions would be great, as I haven't found any forum posts similar to this.
