Does it do this with the charger connected, you didn't say?
Try a full power refresh and check if this resolves the problem.
Here’s the procedure:
Disconnect the charger, disconnect the main battery from the motherboard, (you don't have to remove the main battery, simply disconnect it), disconnect the RTC coin cell battery and then ''press and hold the laptop’s Power on button for 30 seconds'' to reset the BIOS back to default settings in case it was corrupted for some reason, preventing a normal start
Whilst the coin cell RTC battery is out if you have a DMM (digital multimeter) check it voltage. If it is <2.5V DC replace it. I can't find a replacement RTC battery for the laptop online so hopefully there may be some information on the battery itself, that may help to locate it.
Reconnect the RTC battery, reconnect the main battery, re-assemble the laptop, connect the charger and check if it turns on OK.
If it does turn on OK, there ''may'' be a message about the date and time being incorrect. This is normal as the BIOS has been reset back to its factory default settings. Once the date and time have been corrected, the message won't appear again the next time the laptop is started. Also any user definable BIOS settings that were changed by you to suit whatever operating requirements you had will need to be changed back again as well.
Here’s the ifixit [guide|161720] that may help. The RTC coin cell battery can be seen in the image in Step.6, taped to the main battery, lower right side of the image.
