    Hp pavilion 14 - No display
    by Nagyesz
    Hi all,
    Model: HP Pavilion 14-ce3010nh 8BV97EA
    Board number: DAG7ALMB8C0 - G7AL REV C
    Issue: I have an HP Pavilion 14-ce3010nh 8BV97EA laptop. When plugged into the charger, it turns on, but there is no display, the fans do not run, and the processor gets slightly warm. Unfortunately, I haven't been able to figure out what the problem is. I've reflashed the BIOS twice without any success. No post. Already tried out with another ram stick with no luck

    I measured the voltage with the HP turned on in red, and I measured their resistance with the HP turned off in green....

    HP Elitebook 650 G10
    by Dallen Bryce
    Hello, I'm trying to remove the password from an HP Elitebook 650 G10. It's motherboard has two chips, a 32mb spi (W25Q256JVEN) and 32mb ec (GD25B256EYIG). I have created a dump of each, but don't know which one(s) to patch. Could someone point me in the right direction or just patch it for me?...

    Hi,

    I am looking for the schematic of this motherboard or this component, PQB4 reference (Unable to read the text beyond P5)

    Also, if someone with experience could tell me, why would this component burn in order to avoid this happening again?

    Thank you.​

    Lenovo Y40-80 bios
    by goldhawks
    Hi all, I have a Lenovo Y40-80 that I am trying to remove the Admin password for. There is a password screen that comes up immediately that I can input a user password for (Pic 3) and this will allow me access to Windows or the BIOS, but a majority of the options are grayed out in the BIOS (Pic 4).

    I have attached a picture of my overall chassis and a close up of the chip that I have read (using CH341A and AsProgrammer). I output two files from the chip and compared them (fc /b) and they were the same. I patched the first file (the file felt like it processed too quickly) and then...

    Confused - I don’t want to order wrong thing
    by zzpkcq@gmail.com
    Going to replace op-amps in a guitar amp jcr072d

    so TI versions have suffix D IP etc. There didn’t seem to be an explanation of these anywhere. I think they indicate the physical pin characteristics but what do they represent- anyone have a list.

    Does anyone know if these values ​​are appropriate? Board NM-C871 rev 2.0 Ideapad Gaming Lenovo
    by valente222
    I have this equipment that leaked moisture from the bottom, which the PQ3201 damaged the track and does not turn on the machine. remove all two mosfets from that area such as PQ3201(high) AND PQ3202(low). these feed the VCCSA rail. but on this track it has a very low resistance, approaching my absolute zero of my tester to ground (1.3ohm). Could the CPU be bad? I have made this measurement by desoldering the PL3201 coil, taking that measurement on the CPU side.

    On the other hand, on the mosfet side, the PU3201 controller, which is the pwm controller, appears to have a damage since...

    HP ProDesk 400 G6 mini - BIOS Password attempt to remove it
    by beBoss
    Hi,

    as noobie to this please excuse my lack of experience.

    I am trying to remove a BIOS password from this machine:
    [B]HP ProDesk 400 G6 Mini [/B]

    but so far I still have no success.
    I bought [B]CH341 programmer[/B] and decided to give it a try.

    The programmer came with [B]8 pin [/B]cables and connectors or whatever everything else is called so I had to buy a new [B]16 pin cable[/B] because the chip which I think is the BIOS is with [B]16 pins[/B]..
