Hi,
Try the following
a). Turn off the PC and disconnect the power from the PC.
Remove the coin cell battery from the motherboard. Note the orientation of the battery so that when you go to re-insert it, it will be the right way up.
Here’s a link to the owner manual. Scroll to p.107 to view the necessary pre-requisite step and then the procedure to remove and replace the coin cell battery.
Press and hold the PC’s Power On button for 30 seconds to dissipate any residual power in the PC and then release the Power button.
Reinsert the coin cell battery. See note above.
Reconnect and turn on the power to the PC.
Turn on the PC and check if it starts OK.
b). Turn off the PC and disconnect the power from the PC.
Remove all RAM modules (if more than 1) from the motherboard and re-insert just 1 RAM module. Reconnect the power to the PC and turn on the PC and check if it starts OK.
