I have a strange issue with my Compaq CQ 61 running Windows 2012 (server) and I have Googled for it really long and hard and also searched other questions here but in vain. I believe my problem is a little unique.
Firstly, this laptop, unlike my other laptops does not run directly off an AC supply, so when I remove the battery and plug in the charger, it just doesn't turn on. At this stage there is a scope to doubt the charger.
Secondly, when I run it with a battery in the slot, it runs for hours without issues, so the charger itself doesn't seem to be an issue as well.
Thirdly, when the battery is in, and I disconnect the AC charger, the indicator goes from 100% to 0% in about 30 seconds and my computer turns itself off.
Any clues on what could be the issue? Please note that I have tried it with my original battery and doubting it, I have got a fresh new tested battery which works fine.
