Compaq Presario CQ57 Laptop System Bios recovery problem

A customer has a Compaq Presario CQ57 that has developed a BIOS problem.

I am unsure if it had had a BIOS update through HP Support Assistant or if it just decided to start for no reason but it now intermittently decides to recover the System BIOS at start up.

It is all very random. It may not do it for a while - working fine every time it is switched on - but then just decides to go into this recovery. Sometimes the recovery sorts it first time, sometimes it has to go through the recovery mode several times before it sorts it out. Once sorted, Windows and the laptop work fine.

I have tried to remedy it by installing BIOS updates. There are 4 available on the HP website. I have installed all four at various points - sometimes they install, sometimes they fail. Sometimes the recovery mode kicks in straight after - usually after a fail which makes sense. Other times it will work OK for many start ups and then just go back to it's old tricks.

I have attached some photos of the recovery procedure for reference.

Any suggestions would be very helpful.

Thanks in advance.

No suggestions, but to check if there's still warranty or not. That's because this sounds like a bad case of hardware defect, where the memory holding the BIOS is being corrupted every once in a while (after which the recovery kicks in).

I have to admit, I was thinking along the same lines.

Unfortunately, it is out of warranty.

I wonder if faulty RAM could affect it? I will run a memory test to check. RAM can do some strange things so worth a try!

Anyone with any other ideas will always be welcome though!

No, faulty RAM does not affect a laptop as you described. It's definitely a defect purely related to the BIOS ROM. Faulty RAM will affect your computer while in use, as in freezing screen (hard reset necessary) or sudden reboots, with or without the feared BSOD.

I was just thinking that the BIOS checks RAM first after sorting itself out but, of course, it hasn't even got to that part yet before getting upset.

And it would also experience the problems you rightly mentioned once it was in Windows and this doesn't seem to be the case.

I will leave things open for a little longer just to see if anybody else has a miracle cure and, if not, accept the inevitable!

it can be your bios battery just is on the working limit
check that first - or replace it ;  normally - it is a cr2032 model and should read 3 V

No luck with the BIOS battery.  It seems it is the BIOS chip. Customer going to live with it and keep it mainly in sleep mode!
Thanks for your help.
