Re: Dell Latitude 5400 Bios password
so far i used the common ch341 and the blue one v1.7 with voltage select. both freeze the neoprogrammer and the ch341 the moment i connect to usb. used the clip side then the headers. i disconnect the ground wire it unfreezes but then i cant read the chip.Last edited by jetblue; 06-02-2023, 04:00 PM.Leave a comment:

Re: Dell Latitude 5400 Bios password
hi,i have a pickle here. i did many bios dump of 5400 lats and used the methods here to unlock them but this one i have will not allow me to dump. it has a 25b256DYIG smd bios
and it halts every programmer i put it to. the ground seems to be the culprit or pin 4.
i use direct wire soldered to the solder blobs then wire to the programmer.
its a LA-G891P rev1.0 board with the 23VPXY2-8FC8
is my bios chip fucked? it still turns on and allows me to get to setup.Leave a comment:

need help with Apple AcBel 1PC36
hi,i recently recapped a non responsive acbel 1pc36 power supply. i need to know what is the plugged in state for this supply with no jumper wire on the on plug pins.
is it normal for the fans to come on and meter readings on the plug to be normal? or does the start pin need to be bridged to get any readings from the plug?
it seems like its stuck on on and not standby from what i read on the threads.
its not cycloning only when i bridge the other set of pins will it do that but im not sure if its because im not plugging the pins right because after a while it stops.... -
