I have similar problem

It sounds to me that the battery is not connecting to your computer. Is it possible that the terminals have been damaged? Or some other issue that is disconnecting the battery from the computer?

accu Compaq Presario CQ61 100 percent compatible with you Compaq Presario CQ61. I bought two Compaq Presario CQ61 batteries from http://www.accukorting.com/compaq-presario-cq61.html two weeks ago, I felt very surprised, because it fits nearly as good as the original battery.

If you already replaced the motherboard then try replacing the power cord. If you meant you replaced the cord already, the it might be your motherboard is bad.

try to remove first your battery and use only the adapter.

You need to replace your old battery. Don't over charged your battery. If you are using your laptop in your house it is better not to use it with battery. Just use the power adaptor/supply only. Then make sure you will drain the battery let say once a week. =)

unplug the power cable from the laptop
remove the battery then press the power button for 5-10 secs
plug in the power cable to your laptop WITHOUT the BATTERY

try to turn on your computer if still doesnt work try a known good A/C adapter if still doesnt work then mobo needs to be replace

It is not wireless capable out of the box. However, it has 2 free PCI slots for an internal wireless card and several USB ports for a USB wireless adapter.

I hope this helps.
