Hello, I bought a laptop on a garage market but the seller didn't tell me that the laptop has a BIOS password. So my problem is that I'm looking for a solution and I don't know what to do because of 3 reasons.
1. Is it possible to rewrite the bios with CH341A?
2. If № 1 is not going to jail break the BIOS, should I try to change the BIOS with a clean one and is it going to be successfull?
3. If № 1 and № 2 are not possible what should I do, and is there any other option?
Thank you so much guys in advance!
If you need any other information, please just write...

Hi everybody,
I would like to know if the 16v +SDC_IN is normal given that the 19 v comes until the PQS07 and PQS09 mosfets?
If yes i'can't figure it out why and if it's not neither😁
The upper part with PQS27 and PQS24 is not populated on my board
You can find the schematic on page 84
Could you help me with that?

Thank you already....

Hi everyone,
I have two Dell 7420s with the WWAN port disabled, probably due to a BIOS lock.
I tried installing two different cards in both PCs, but neither of them detects it in the peripherals. I've reset the BIOS and tried everything possible, but the problem persists.
The same cards on other PCs I've tested work perfectly. Do you know if there's a way to enable it, perhaps directly from the BIOS chip I read about?

Thanks in advance for help....

Dear friends. I am working on a LENOVO THINKBOOK 15 G4 IAP Motherboard No: LA-L931P REV 01. The motherboard turns ON fine with or without battery & AC power, & battery charging is good too. This is for the first time till the power adapter is plugged in. When Laptop is in ON position, as soon as I remove the USB-C main power & plug it back again +20V_VIN is no longer there (Missing) & battery does not charge at all., I thought that the TPS65994-AE Chip was bad., so replaced it with a new good chip, but the problem is still there. On the battery charging chip BQ25710 where pins...

Good day to all, I have a big problem. I can't find the eeprom dump for the Eizo CS2740 monitor. The device doesn't turn on, the indicator just lights up. It responded to connecting to the PC once. The update process started with the standard program and then disconnected from the computer. The computer doesn't detect it anymore. If anyone has an eeprom dump, please share.

Got this Fender Acoustasonic 100 in for repair.
Complaint: Supposedly does strange things, the instrument channel goes pop, crackle, no audio then all of the sudden works again?

Well... Open this 15 year old sucker up and I am greeted with leaking capacitors. I changed these out, cleaned the board and no audio out of the instrument channel, but some weirdness is gone and sounds now clean on the second channel. So I put my laptop on there and cranked the music full tilt. Sure enough, it goes crackle and pop with the bass in rhythm. Put my signal geni on it and sure...
