Hi, i have recently purchased an Acer Travel Mate 5730. If you boot the laptop when connected to the mains power all is ok with the laptop but if your remove the mains supply the laptop within seconds will freeze. I can boot without the mains supply and just battery only and the laptop will boot so far and then again freeze. The points at which it freeze vary during boot up. I have tried several things like disabling all services during boot up and removing most if not all application from the laptop but still it will freeze when the mains power supply is unplugged. I have checked all the drivers and all windows updates and all is up to date. The laptop will work fine in Safe Mode but i have been unable to lacate what that doesnt occurs in safe mode occurs in normal boot.
The laptop was delivered with Windows Vista which i downgrade to XP Pro. I dont know if the issues occured in Vista as it was instantly downgraded. But the laptop is certified/passed for Windows XP and i used the supplied disc to perform the downgrade. I have reset the battery and booted with out the batter. But no difference!!! Any suggestions!!!
