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?...05-29-2024, 06:29 PM

I am trying to downgrade my bios on my Alienware so I can undervolt & overclock my CPU, and overclock my ram. I need to get to bios 1.2.2 for this. Dell doesn't allow downgrades, and their bios file is an exe compiled in c++, so I can't decompile it easily. I am wondering if I can flash the bios manually using a usb flasher. I would like to know if this is possible, and if so, where the bios chip would be. I know flashers are pretty cheap and the bios chip is 8-pin. There are two of these chips only when I open the back panel of the laptop. I'm not sure if there are any on the other side of...05-17-2024, 03:34 PM

Hello to everyone.
My [B]W26361-W84-X-02[/B] motherboard starts but don't show image (no logo screen neither bios). Because, I have two of them I desoldered the bios chip from the no working motherboard and I soldered it to the working motherboard and the motherboard works OK, so the bios firmware isn't the problem. Below I took some measurements from the no working motherboard when is power on. Also, I replaced the RAM and didn't work again (maybe some pins from the RAM slot don't have the right voltage?). I replaced and the bios battery, and I made reset on the bios and again the problem...05-23-2024, 03:51 PM -
Hello
I have model AHL50/abl52 LAC710p - ac120ns. It doesn't turn on after connecting the battery. The battery is charging correctly. I remove the battery, restart the bios by pressing the start button for 30 seconds without a charger and it works. I connect the battery, press the start button and it does nothing.
When it is on and I connect the battery, I reset it and it works and detects the battery.
I have measured some voltages according to the schematic and they are correct.

Hi all.
Recently I picked up a vintage HP 37717B communications analyzer which uses one of these MML200 Coutant power supplies. Needless to say the PSU is not working, and surprisingly there is apparently nothing available on the web regarding repairing one of these. No stories, no schematics, zilch!
There[I] are [/I]however many companies offering repair 'services', however I don't have the luxury of sending it off, so am intending to do the repair myself.
I admit right now that I am no expert on smps repair, although I do have a grasp on the principle of the general...05-29-2024, 08:23 PM -

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

Dear Members,
This laptop used to work with a 19v 3.4A adapter.
After 4 years of using it, now, the adapter's output voltage drops to 17v when windows loads up. Then the laptop suddenly turns off.
Today, I have connected a 19.8v 4.5A adapter to this laptop. Then the adapter's output voltage dropped to 19.4v but the laptop worked fine.
In addition, I noticed that the cpu power coils get warm to about 50'C but the mosfets are cool.
All the voltage rails on the mainboard are fine without any reduction except for the 19v rail. All the ICs and coils on the mainboard are...Today, 01:36 AM -

Hi !
I wish to know how to remove SVP from this model with I7-8565U CPU.
Try already the MEC method, read EC-erase-wait5 min-write back but password remains.
Obviously the Lenovo Autopatcher not working for 8th gen CPU.
So how to do it?
