        Hi rex98, thank you for the answer. I tried your BIOS, but the behavior keeps the same.

          Re: Hp probook 640 g1 bios

          Maybe this is not a problem with the BIOS? A year ago I got this notebook and it had the problem described here. After cleaning the ME region, it suddenly works again. But after a few months it stopped working and the same problem like now appears. I had no time to fix it and leave it in this state until now. I resoldered my cable to the flash chip and readout and flashing incl. verifying works. So I tried the same procedure like that time but now I can't get it working again. Are there any other reason why caps lock is blinking 5 times followed by high speed CPU fan? I have read that this is happening when the embedded controller does not get the BIOS POST message within a certain time. So does this mean that it can't have anything to do with some power rails? The flash chip is getting 3.3V at VCC.

                    Thanks for your help. Tested the new BIOS and machine turns on with display. However got the following error message:

                    What's wrong?

                        You just need to restore DMI. I don't have DMI for this device so I borrowed from other devices, only the serial number and product are yours.

                          With this new dump there is no picture after powering up. Problem is the same as with the original bios dump.

                          Any idea?

                          Thanks for your help!

                            If your original does the same then more then likely u had a bad read or the og bios was already bad. do you get any power atall like fans spinning ect ?

                            Well it is much better then before, but there are still some missing information. Product family and System Board CT number are missing if I understand well.

                            Entered into BIOS and find the following informations.

                            How can I update the missing informations as well?

                                Hi,

                                Thanks for your help.

                                Now the machine powers up without error message, but every motherboard specific information are incorrect. Serial, SKU, system info, etc... How can I restore my original data?
