I have been having a few problems with an EISystems laptop, a 3100 model and so went to the Microsoft updates site, downloaded and installed the updates recommended including SP3 and now the laptop will not start up. I press the power button and I get a brief whirr from the cd drive and the cd light comes on for maybe a second and then it all shuts down again. Does anyone know if there is anything I can do to remedy this? I have tried on mains power, on battery, I have diconnected mains and removed battery and reinstalled it and nothing helps. It probably is not worth taking to a professional but I cannot afford a new one!
Just a thought is the mains adaptor working have you got a voltage on the connector on the end? Have you got a meter to test it? This would explain start up and shut down with battery attached as proberly just enough juice in the battery to start pc,and no power when battery disconnected as no power from mains.
