HP Pavilion m9698D cannot boot up after CMOs battery change

hi

my boot up of HP PC recently encountered some CMOs error, i thoughtthe CMOs battery might be flat. i changed the CMOs battery and nowthe PC cannot boot up. the power button on the tower casing just flashed blue , followed by orange, the internal fans spin for a while and PC will shut down without OS screen appearing and the PC just restart again. this blue-orange-shutdown/restart repeated itself with nothing appearing on screen

 

i swapped back the flat CMOS battery and the result is the same

 

appreciate advice, if any. thanks!

CKGoh, welcome to the forum.


When I see symptoms such as you are experiencing, I immediately suspect the power supply unit (PSU).  Here is a guide that will help you troubleshoot it.

 

Also, you should test your memory.  The best way is to remove all of the memory and replace it one stick at a time and boot.

 

Please click "KUDOS Thumbs Up" if I have helped you and click "Accept as Solution" if your problem is solved.

Re: HP Pavilion m9698D cannot boot up after CMOs battery change

i tried the steps in the guide. doesn't help. my PSU light is strong and steady. but i did notice a red light flash from the ATI graphics card before the shutdown. what does this mean? PSU gone or need to re-seat my graphics card?

 

its really a simple CMOs battery change LOL.

Thank you for the additional information.

 

Sometimes what appears to be a simple CMOS battery change may be a symptom, not a cure.

 

Did you test the memory as suggested.  I have seen memory also cause the symptoms.

Okay, turn off the power.  Unplug the main ATX power cable from the motherboard and replace it.  Also, check all of the connections to assure they are tight.

This is one of the hazards of working in tight places with sharp edges.  I cut my fingers everytime I work inside of the case.  No matter how minor the task.
