Re: Bios need HP elitebook 850 G1

I have difficulty with my tl866 read the source of the two chips, I have to remove (chek-id) on the program minipro to be able to read them and I think the empty content. Both the bios and the ec chips.
the laptop does not show signs of life no LED but there is voltage at the ends of the battery.
attached the two sources

A mainboard HP code is 730809-001

There was a little bit of code in U366Old ,check your tl866 firmware and reseat in zif socket . Are you using a clip ? ,if so desolder them.

Re: Bios need HP elitebook 850 G1

Yes they are desolder, I did the upgrade but did not improve, I will buy the new version tl866 2 plus

Re: Bios need HP elitebook 850 G1

Try these. The first bios old1_ME CLEAN is your bios with clean ME.The 2nd has the latest update merged,but you will lose DMI info,you may have to use nbdmifit/BCU to add the DMI info.

Re: Bios need HP elitebook 850 G1

Update, with the last bios now the laptop only turns on the white led for 10 seconds then turns off and turns on the orange one for a moment. then the orange-white LED turns on alternately 2 times. The fan does not start and neither does the video

Re: Bios need HP elitebook 850 G1

Re: Bios need HP elitebook 850 G1

Can you post your U366 dump .Is the motherboard part number one of these: 6050A2560201-MB-A03
6050A2559101-MB-A03

Re: Bios need HP elitebook 850 G1

Yes it is

Re: Bios need HP elitebook 850 G1

Try this new EC ,if it doesn`t work i think the problem must be somewhere else .

Re: Bios need HP elitebook 850 G1

Thank you very much for your support and help but continue to make the usual LED signals. Probably the problem will be on the chipset or video. I have always had problems of this type with elitebook series laptops sometimes they do not turn on and abnormal flashes of the LEDs
