when ac goes out my system goes off

Specs: windows 7, core2duo
My Dell E4300 laptop just suddenly stop charging it gets to 35%(writes plugged in, not charging), later it dropped to about 28% then i did some windows update and then it increased gradually to 40% then stops charging. I have tried other power adapter with less volt to mine - it even worst, mine still charge but those other ones just powers my system but does charge. My guess was that the battery was bad but the irony is that even that 40% charges last normal(that is it does not drains out fast at least for about an hour). The real challange now is that i made some changes to BIOS(i change the charging to express charge) then it charged up till 50% then stopped charging only for the power AC to go out and my system goes off. My battery has a meter which indicate that the battery is half charge. Now without power ac i tried putting on my system and it's not coming up, no light nothing but with AC power it comes. I don't know what to do please help

Best first step is to go back into BIOS if you can and undo what you did so that at least you are working on AC again. Not sure if your main issue is battery - hang about to see what others think.

Always pop back and let us know the outcome - thanks

Hi Remnez, it is important to use a correct psu for your laptop. You are asking for trouble if using an incorrect one.

Remove/replace the battery 3 or 4 times to clean its contacts.

You have not advised how old the battery is. If it has had a year or more's usage, I would suspect it.

Here in the UK (where are you ?) oem batteries are inexpensive, compared to those from the laptop maker. Select one with a higher wattage, but the same number of cells. Do not go for the cheapest, but one with a guarantee of 1-2 years.

If using for long periods at home, consider running with the battery removed.

Good Luck - Keep us posted.
