A200 Toshiba Satellite Random Restarts / Freeze When on AC

Symptoms:

  • Random restarts
  • Boots ok on battery
  • Toshiba A200 Satellite laptop
  • Over 4 years old
  • Works in safe mode


Solutions:

  • Boot up in Safe Mode
  • Start > Control Panel > System > Device Manager > Processors
  • Disable both processors
  • Restart the laptop
  • Boot into normal Windows
  • Should work fine, if not you may want to look at the rest of this blog
  • This is apparently a temporary fix and your laptop will not last years and years without replacing a chip (see below)


Causes (Possible):

  • Poor battery life and power switching between AC and battery
  • A NEC chip on the motherboard that regulates power is deteriorating and causing the laptop to not power properly


Alternative fixes:

  1. Set power settings to Power Saver
  2. Set power to High Performance
  3. Boot into BIOS and change Dynamic CPU Frequency Mode = Always Low (NOT DYNAMIC)
  4. Charge up battery and only use laptop on battery

  2. Working in safe mode, disbabling processors, etc are temporary solutions that may last up to around six months. The permanent fix is to replace the capacitor as shown here: http://gs138.photobucket.com/groups/q251/S1BXDWUERU/
