Hi, When you replaced the CMOS battery was the main battery disconnected from the laptop? If yes ignore the following If no try a complete power refresh and check the results. Turn off laptop if on Switch off charger and disconnect charger if connected Remove main battery from laptop. Disconnect CMOS battery from motherboard Press and hold the laptop's Power button for 20 seconds then release. Reconnect the CMOS battery Connect and switch on the charger (leave the main battery out at this stage) Try to start the laptop. If it starts allow it to boot all the way to the Windows desktop and then allow the HDD activity to settle a bit i.e. wait about 5 minutes Shutdown the laptop in the normal manner. When it has completely shutdown, switch off and disconnect the charger, reinsert the main battery, reconnect and switch on the charger and turn on the laptop. If it starts allow it to boot all the way to the Windows desktop, allow the HDD activity to settle a bit and then check the charge status of the battery. If it is charging allow it to fully charge before switching off and disconnecting the charger from the laptop.
