by mzk10kHello
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.

by Luke11037Hello everyone,
I have an ASUS Vivobook 14 OLED M3401QA which is not posting. Currently when plugged into power/turned on the power indicator will illuminate and the battery indicator will flash white roughly once every 3 seconds. Leading up to this it would sometimes turn on and then other times not turn on, furthermore it also showed a screen saying "new cpu installed, fTPM/PSP NV corrupted or fTPM/PSP NV structure changed" and then a screen telling me to recover the bios however it is no longer even posting at this stage.

by MireniaHi everyone,
I've got a Lenovo Legion 5 15IAH7 with no post/no boot issue.
The mainboard is a NM-E241 Rev 1.0
Now I am searching for the BIOS chip so I can reflash it.
But I have some difficulties to identify the correct chip. The schemantics somehow are not really helpful for me (I am a beginner with Laptop schemantics)
I found 3 Winson chips and one GigaDevice chip as you can see on the screenshots.
My guess its the W25Q128JVSIN (UB3) because it is the biggest from all.

by zwectI have this Asus ROG laptop (the 1060 + 6700HQ variant) which lights up the power button's LED when i plug the charger in but does nothing else. Opening up there are no signs of any burnt or corroded components, i've checked the resistance of both CPU and GPU's cores on the caps underside them, the CPU's VCCCORE's caps read 1.2ohm and the GPU's NVVDD read about 0.5 to 0.6ohm. I then tried to check any voltages while the laptop is plugged in (without any of the removable parts) and the GPU's core voltage instantly goes to 0.8v when plugged then getting slowly warm, the PCH does so too (not so warm...Today, 06:23 PM

by eagleeyezHi,
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?

by goldhawksHi 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...4 Photos-

by MireniaHello everyone,
My Legion 5 15IAH7 won't post. won't boot. No fans, no keyboard backlight.
Online power led and charging led lights up.
My guess is that there is some issue with the BIOS.
It's the NM-E241 Rev 1.0 motherboard.
As I found out there are two BIOS dumps needed for this board.
One 16MB and one 8MB.
I've got both uploaded. Can you maybe check and fix this BIOS files?
Thanks a lot in advantage ...-

by Arc717I 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

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 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?...

I have a MacBook Pro , board 820-2915a and it turns on , chimes etc etc , keyboard lights up, fans spins , can turn caps lock on/off but screen is dead.
Iv tried the resets , shine torch through back logo , nothing , it seems the screen has no power. If I plug charger , it charges but if I disconnect battery it displays green light but won't turn on. Iv tried screen on with another board & it works & seems I'm not getting any voltage at pin 2 , next to ground pin .
