Windows 7: Problem with Lenovo Thinkpad T61

Problem with Lenovo Thinkpad T61

I've formatted the laptop and it worked great, but I saw that there was no wireless card and opened it to insert. I put a card from Dell laptop and when I turn on laptop, I got this error:

ERROR 1802 Unauthorized network card is plugged in - power off and remove the miniPCI network card.

I searched the internet and I saw that for this error, solution is updating/flashing bios with "whitelist removal". I did it and turn on the laptop and it worked normally, until I unplug the charger.
Whenever I unplug it from the charger, laptop shut down immediately, just like it is without the battery in it. I tried to get back the original bios, but still the same. It shut down in Windows (7 32bit), in Safe Mode and in Bios.
So the laptop is running great when I plug charger, battery shows a 100%. Previously battery held around 2-3h.

Solution ?

Sounds like it`s not getting a good connection to the battery. You should get it serviced.

I don't think so. When I reset battery trought Power Management, the battery charge full, then decharge and charge again, so I think that battery is well connected.

I meant connected to the laptop, not to the charger. Unless that`s what you mean also.

Is this a card which you know is meant for your laptop?

If the issue with your battery began when you updated the BIOS, I would try the update again or roll it back to the previous version under which it works correctly.

Also compare the steps for getting a perfect Clean Reinstall - Factory OEM Windows 7 to see how close you came to following the very best practices based on thousands of installs we've helped with here. Did you import a bunch of drivers that weren't provided by Windows 7 installer or Updates?
