i had a compaq presario 2200 series, its battery died a year ago, nowi decided to buy some 3.7v li-ion battery and replace the ones in the battery.

so i did everything but now the problem is that, i do get that 11.1v on board but i do not get power on the laptop battery contacts, and the power led checker also does not work.

can anyobe tell what the problem might be ??????????
