Re: HP Elitebook 840 G5, verify fails, update



Hi again.

Installed AsProgrammer_2.0.0a14. Dumped the Bios and verified ok. Dropped the bios file in RCUnlocker, got message that I should try the other chip (the 16 Mb). Took laptop apart to have access to the W25Q128JVPQ chip on the hidden side of the mainboard. Soldered the wires on the pads around the chip. Read the chip and verified it a couple of times. Dropped the bios on the RCUnlocker and it removed the bios password. Erased the chip using the CH341A, verified that it had been correctly erased....

Hello guys,

I am trying to remove the adm bios password from an HP Elitebook 840 G5 but I am having trouble. When I press "verify" it always returns the error "Chip Main Memory with the contents are in disagreement."
The leds on the CH341A usb programmer indicate the chip is being read.

I already verified the soldered wires with a multimeter and they look ok.

I tried a PC with windows7 and a different one with windows 10 yet I got the same error.
What am I missing? I read as much as I can but cant get over this first...

Re: Antec True 380SP + Fuhjyyu cap - lights out



That would be handy, although to ship this brick to Brussels...

Anyway, fortunatly I don't have a machine down waiting for this thing. I found this along with other trashed psus that I didn't even bother to look inside until I started to look for those caps. Its just that these Antecs got good reviews when they appeared. Its a pity all these Fuhjyyu's inside.
Hardware reviewers should re-test products after working for a while to measure reliability and publish their findings.
thks...

Hi Tiresias
Thanks for your help
Thanks to the manufacturers links in this forum, I found identicaly sized replacements for the two Fihjyyu's :

Nichicon: LGN2D47MELA25, LGG2P471MELA25
Rubycon: 200MXG470M, 200USC470M, 200USG470M
Sanyo: series PE-HC, PE-HD, PE-ED

I am sure there are others. The problem of course will be to be able to buy two of theese whithout having to pay for a truck full of them

The extra 5 mim lenght of the Panasonics would probably still...

Helo Everyone
Somebody trashed this PSU for a good reason, it blows the fuses at home (and god knows what else with it). Since I like a chalange, I am trying to recover it. This time the bad cap is on the imput side, a 470uf 200v. My humble theory: the cap has gone bad, which caused a Mosfet (k2996, already replaced) to fail (completly shorted) and of course: the fuses at home go and with it chuncks fly off the green thermistor.
The thermistor is a pain to get, a SCK0510, 10A max, R 5, the closest I got is 10A, R 2.5 (dont think the beast will complaint too much about the 2.5 O difference),...
