I have a Microsoft Windows model name a6437c Hp Pavilion which had Vista then 7 Home Premium,during a image backup system recovery had a power failure and system was severely compromized so I cleared the hdd and had a new partition wrote to hdd NTFS version it is flaged as set active and as primary.About one out of every 25 startups the monitor might have a picture then flash something at botom of screen about BIOS being corrupt or missing.Monitor is definitely getting signal power all fans,all lights,dvd seems to work and power buttom you have to force power off hold till it goes off.Four long beeps with a pause then repeats.Oh all this was going on before servicing hdd.I did have some chances to recover but they were unsuccessful to this point.But without monitor and no way to remote system I am not sure what to do.No boot need help.Please
As far as I know, the HP Pavilion A6437C uses a Foxconn MCP73M01H1 motherboard. This uses an Award BIOS. Unfortunately I can find no documentation that mentions a 4 beep code with an Award BIOS.
What you could try is to unplug the power to the computer, and then remove the CMOS battery from the motherboard. Leave it for an hour or so and WITH NO POWER ATTACHED press the power on switch and hold it in for about 30 seconds. There may also be a jumper to clear the CMOS settings. You could try resetting it by (with the power unplugged) move the jumper across and then move it back again.
Hopefully when you power up again the BIOS message will be no more.
Hi Brian Thank you again.Well I did you all said in the order you laid out.Results monitor shows no signal then goes to sleep fans still work green power light near cord works but that is about it.But I did find something on the motherboard.I think I found 5 capacitors on the board same size with their tops pushed up and orange looking dry stuff they are tucked in around processor.Still needing input on this.Thanks Brian
