Computer wont boot after CMOS battery install

[Silverthunder]

I installed a new CMOS battery into my computer.  Now the computer wont boot.  Instead, the computer makes a short beep and then a long beep, and continues that pattnern. 

I was reading online that I need to figure out what that beep pattern means.  Each bios manufacturer has different meanings for each beep pattern.

Greetings,

Welcome back to the forum.

I am not a HP employee.

Your PC is no longer supported by HP if Pavilion A6040n is the correct product number.

Why did you replace the CR2032 motherboard battery? Did this error condition exist before you replaced the MB battery? You may have damaged the MB if the answer to my last question is no.

One beep could be any number of different problems depending on the date your PC was manufactured and the BIOS manufacturer HP was using at that time.

For example, possible BIOS error conditions resulting in a one beep error code:

Memory Timing Failure,

No Media Detected,

Legacy Floppy Drive or CD/DVD Drive not detected.

I replaced the cmos battery because the clock was losing time.  The clock continued to lose time even after I installed a new operating system.  In any event, I didn't see much harm in changing the battery because it costed only $2.

The computer model number is correct.  I am not surprised that it's no longer supported, as the computer is now quite old.

The computer did not have any such symptoms (not able to boot) before I took out the CMOS battery.  When I took out the CMOS battery, I disconnected a USB to motherboard cord so that I could gain better access.  However, I think I plugged it back in correctly and I even tried keeping it disconnected and that did not help either.

Thank you for the ideas of what the beep could mean. 

Let me know if you have any ideas of what I should do.

Hi Silverthunder,

You're very welcome.

Replacing the MB battery was the correct procedure. 

It's tough to troubleshoot a PC without having access to hardware specs. Old age points to hardware failure.

I can only tell you to investigate the possible error conditions in my first response.

The system may be at the end of it's useful life.

Here is some info that I saw printed on the motherboard:

PSLP-LE

Rev 5.03

N13219

I did a web search and it seems as though this is an Asus motherboard.  So far from what I am reading, it seems to be a problem with the Ram.

Hi,

Best wishes.

You have work to do.

I took out one ram stick, put it back in.  I repeated this for the other ram stick.  That seems to have fixed the problem.

Shortly before this, I also disconnected and reconnected the sata cable, though I don't think that had anything to do with fixing the problem.
