Oh My.
After flashing the KB9022 with my new RT809F flasher, I got LIGHTS!! woohoo!
but then, I had messed with one of the SMD DC to DC chips (EM5209VF) when I was poking around looking for shorts so I had to wait another two weeks for that chip to arrive from china (the only place I could find it online)
Just soldered it on... and now she boots!! This was my first board repair....I'm so proud of myself!! My two new shiny tools actually paid off, the RT809F flasher and my hot air rework station....Leave a comment:

I received my programmer today... should I try flashing bios first or the EC? which one is more likely to corrupt?
(I'm getting no power led on DC-In - logically what controls the power led? i would think the EC)Last edited by moophus; 03-27-2017, 02:21 AM.Leave a comment:

oh my, looks like I need to buy a programmer... is it the RT809F?
So what would cause the firmware in KB9022 (EC) to get corrupted? Could it just be in a limbo state and need a reset?Last edited by moophus; 03-11-2017, 05:06 PM.Leave a comment:

Thanks Techman,
RSMRST is 0v, does that mean EC isn't running?
Is the +3VALW = S5 3.3v? - it's always on
Yeah, no lights on DCJ jack plugged in.... neither any devices (mouse,keyboard) - So how do I flash bios without a working PC?Leave a comment:

No lights, no power.
19v DC in is OK
3v and 5v ALW has power as well but all the rest of the rails are off and the schematic shows they all have SUSP# as input.
I'm not getting voltage out of SUSP# from the EC. The voltage lines going into EC test ok.
SUSP# is 128k ohms to ground.... is this normal? or perhaps a short to ground somehwere? hoefully not in the EC.
The computer was brought into a university repair corner because of a harddrive crash. Whilst they were "repairing"...Last edited by moophus; 03-09-2017, 10:59 AM.Leave a comment:
