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 ?
