HP ProBook 645 G1 Bios dump
Hi,
Can somebody share dump for HP 645 G1
Or instruct me how to edit BIOS file from HP site. I downloaded bios but it is empty with serial, model etc... and when I turn on laptop it always says that following data is missing.
So I have my old bios dump (locked) and new from HP site without those data.
Eprom dump will solve my problem because serial no is not important to me but knowing how to edit HP bios will be much more useful.
Thank you! -

Re: macbook Pro 2011 15" A1286 won't power on without battery
I have green/orange light. Everything works fine, except power on without battery.
I've just tested with ASD and it passed without any error.
Very confused about this......Leave a comment:

Re: macbook Pro 2011 15" A1286 won't power on without battery
Same problem here...
Motherboard 820-2915, won't power on without battery.
If I connect battery and power it on, I can remove batt and it will remain on if connected to DC, but it won't start only on DC.
It can powers on only on battery normaly.
Looks like common problem because I have two mobos with same issue.
Already changed U7000, but same problem persist.Leave a comment:

Re: Macbook Pro 13 A1278 EMC2555
I have the similar problem, same board...
It came with PPBUS_G3H shorted to GND at Q7035.
I have changed Q7035 ang got green light and fan as well.
But unfortunately I have no display, chime, anything...
Also tried to power on without RAM and it runs in same way, no beeps...
When I plug the charger with battery inserted, green light go off after couple of sec and no orange light came on. So I have SMC_BC_ACOK at U6901 without battery and not with battery connected.
I tried with changing U7000 - same...
On...Last edited by cvorke; 04-28-2016, 11:28 AM.Leave a comment:
