Having problems with your HP Pavilion m7480n (882780389410) PC Desktop ?

Will not boot up. Get Bios Rom Checksum error, Keyboard error or no keyboard present. Manually shut down and turned on literally 30 times this morning before it would boot up. Then after a couple of hours when I wasn't in the room, it must have shut itself down, then wouldn't reboot, got same Bios error over and over again. What is wrong.


Answers :

Most times a checksum error refers to the cmos battery. you may want to replace the battery and see if that helps. However this can also be a symptom caused by a bad power supply or a faulty board. Make sure you check your motherboard's capacitors for swelling or leaking.

hope this helps.
