I'm back with a new problem. :) I have a Medion Akoya E1210, a MSI Wind U100 copy, netbook. Whenever I unplug the power adapter the netbook dies. Replugging it boots it up again. At first I thought it was the battery but I have another battery (we have 2 medions) with same results.
Taking out the battery and waiting for about 15 minutes leaving the netbook unplugged I replaced the battery and it boots fine. Plugging in the adapter gives no problems then. Unplugging the adapter while the system is on gives same problem.
So I think it has something to do with the voltage regulator on the motherboard, but I'm not sure. Anyone else seen this problem or has some ideas? Maybe I'm looking in the wrong direction.
