Laptop won't power on with new battery.

Hi @gatlboy

Try a full power refresh in case the BIOS is corrupted preventing a normal start and check if that resolves the problem.

• Disconnect the charger from the laptop if connected.
• Open the laptop and disconnect the battery from the motherboard. (You don't have to remove the battery, just disconnect it)
• Disconnect and remove the coin cell RTC battery from the motherboard

Here's the service manual for the laptop. Go to p.23 to veiw the procedure to remove/replace the RTC coin cell battery from the motherboard

When the RTC coin cell battery has been removed, measure its voltage. If it is <2.5V DC or if the battery is >4-5 years old, replace it.

• Press and hold the power button on the laptop for a full 30 seconds and then release it.
• Reinsert and reconnect the RTC coin cell battery
• Reconnect the battery, reassemble the laptop, connect the charger and check if it turns on OK.

If the laptop turns on OK, there might be a message stating that the date and time are incorrect. This is normal as the BIOS has been reset back to default by the above procedure. Once the date and time have been corrected, the message won't appear the next time the laptop is started. Also if any user definable BIOS settings were changed by you to suit whatever system requirements were needed, they will need to be changed back again as well.
