It seems that the 16GB eMMC has some problems and I would like to install a bigger hard drive, a regular 2.5" SATA SSD drive. On a similar laptop schematic (Quanta ZM8 r1A) It looks that the CPU Celeron 2955U has some SATA ports available that may have some test points on the motherboard.
Can somebody help with the schematic and to confirm if a SATA SSD drive can work with wires connected on these test points? Also a SATA SSD drive can work with +3.3V taken from the motherboard?

For the "beeping" board I have discovered the root cause of the beeps: The processor was missing. I have put a G3900 on this motherboard and it is working OK, also the bios from @SMDFlea.
Does anybody know if the processor G4560 is working with this motherboard? I have found on Q150 chip set specs (on [url]http://www.cpu-upgrade.com/mb-Intel_(chipsets)/Q150.html[/url] ), that it is supporting this processor.Re: need bios HP ProOne 600 G2 21.5-... the "beeping"

Thank you @SMDFlea for the prompt reply.
I have tried the bios that you sent, but the behavior is the same. There are 3 long beeps(led on the power button is flashing red 3 times) followed by 4 short beeps((led on the power button is flashing white 4 times) and the fans are not spinning. This HP ProOne 600 G2 has suffered a power surge, together with other similar PCs. For some of these PCs, I have found some short-circuits on the power supply phases for processor, that have disappeared after I have removed the...

Hi

I have a HP ProOne 600 G2 that is beeping 4 times with power led flashing. I do not know if the bios is the root cause of the issue. I have attached the bios that I have read from a Winbond W25Q128BV chip.
Please confirm if the bios is a valid one....
