Thank you so much, you're absolutely right, and it worked perfectly with the correct settings.
I was able to flash the EC, and the device is working correctly.

I need some guidance. I replaced the ITE8586E chip in a Lenovo L340-15IHR. It previously had a short on the +3VL_EC line, but this is no longer the case after the replacement.
To program it, I bought an XZZ ITE Programmer. I connected it to the battery's CL and CK pins, and when I select TypeAuto, it detects a W25Q128JV, which corresponds to the BIOS SPI ROM. If I read it, I can dump the BIOS from there, but it never shows the ITE.
I desoldered the BIOS so it wouldn't interfere, but now the program always gets stuck on "Please Turn On ITEEC Power".

Hello, I hope someone can help me with my problem.
None of the keyboard keys work (not even in the BIOS) after a Windows update.
I downloaded the BIOS from the HP website and proceeded with the manual update; it completed "successfully," but after that, there was no display.
Model: HP Probook 440 G8
ProdID: 658X8LP#ABM
S/N: 5CD2116P2N
Board: DAX8QIMB8B1
When it turns on, the CPU fan spins at maximum speed, and the F5 and F8 keys light up orange.
There is nothing on the display.
This model only has SPI and EC chips,...Leave a comment:

Hello, I have a Lenovo Ideapad 330S-15IKB [MB: 330S_KBL_MB_V06] [SN: YD04PY5P] with soldered RAM.
The customer reports that the computer was running, began experiencing graphical glitches, and shut down, never turning back on. When I connected it to the power supply, it showed around 350-400mA of power consumption, which remains there and never produces an image. I've measured the power supplies, and the voltages are correct. I suspect a RAM issue, which is common on these computers.
I need to disable them. Reviewing the schematic, there's no resistor configuration that...Leave a comment:

Thanks for your reply. I was able to flash it and it worked a few times.
But then I put the battery in, charged it to 100%, and it wouldn't turn on again. When I plugged in the charger, it made a coil whining sound, with a 150mAh consumption. It's probably some electrical issue on the board....Leave a comment:

[Request] ASUS Vivobook Go 15 PROCHOT Dissable
Hi, I have an ASUS Vivobook Go 15 E1504G (E1404GA-MB) it has a Core i3-N305 Alder Lake-N processor that is stuck at 0.4Ghz all the time, whether on charger only, battery only, or battery and charger at the same time.
The ThrottleStop app shows me "BD PRO", and it won't let me disable "BD PROCHOT", according to research Intel disabled the possibility of modifying "BD PROCHOT" from the system, and now it is blocked.
There are no diagrams of this board so I wouldn't know where to go to look for the physical problem on the board.

Tomorrow I will try to measure all the sources and the PGOOD, if that does not work I will have to give up.Leave a comment:

In order to perform maintenance on this equipment, the battery must be removed, so I don't think that's where the damage comes from
Yes, when removing the screen it keeps turning off at exactly the same moment
Regarding DRAMRST# and PLTRST_CPU# I am attaching captures from the oscilloscope, the first is DRAMRST#, both are from the moment the equipment is turned on, until it turns off by itself
Regarding the PGOOD, I haven't measured them all, but I have VCC_CORE, VCCSA, 1.2V_DDR, 3V, 5V, GPU_CORE...Leave a comment:

DELL G5 5587 LA-E993P Power on, but no video
I have a DELL G5 5587 LA-E993P here that after a maintenance process (changing thermal paste, thermal pads, and general cleaning) turns on for a few seconds, but just before showing video it turns off.
When connecting it to the power source it indicates normal consumption, and when pressing the power button the fans spin to maximum, and after a few seconds it turns off.
I can see that the screen turns on the backlight for a fraction of a second and then turns off along with the entire computer, and the boot process restarts.
If I remove the RAM then it shows color codes... -
Just for the record.
I managed to repair the graphics card by replacing that integrated LS3018NG (Q7), searching the schematic I realized that there is another one exactly the same that controls the voltage of the USB-C that the graphics card has, so I removed that integrated, and replaced it with the defective Q7 .
I have not tested the USB-C on the card since I do not use it, but if there is no replacement, such a repair may be viable.
For my part, I will order that component through Aliexpress to make the USB-C functional again.Leave a comment:

Did you manage to solve that problem?

Acer Aspire 4520 won't turn on after reboot
Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.
It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.
The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.
If I remove the... -

Hello, I have in my hands an HP EliteBook 1040 G4 (DA0Y0UMBAD0 REV: D) that makes no attempt to turn on, display an image or anything.
I took out the BIOS and flashed one that I found in a forum for this model, and on the first boot it did give a power LED, it showed an image, but I got two HP screens, the first one said:
"Final step of BIOS update is in progress.", after that it turned off and turned on again this time showing the following warning "The BIOS has recovered its identity data from the Embedded Controller due to data mismatch."

Re: Epson PowerLite Presenter L 3 Red LED's Flashing
Of course, no problem. What type of photos would be necessary?
From the projector itself, from the projector board, or from the three lights flashing red?Leave a comment:
