Dell 7420 wwan port disabled

[Blackwolf76]

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...

The laptop is working, but when I press the power button, it takes a long time to display the logo screen. The service tag and original BIOS file are attached. Please fix the BIOS....

Hi, I'm working on a Legion 5, NM-C221 Rev. 2.0 board. Charging port replacement butchered by other shop and EC took a hit. I ordered replacements from China (shums) soldered it on and nothing happens, no lights. It does get 3.3V bot no 5V, draws 50mA. I read on another thread (Lenovo y540-17IRH IT8226e-192 - Badcaps) that it should auto-program but I'm not sure how that process works, should I wait 30s, 1min... then lights will come on, do I need to flash a particular bios or is there something else wrong with the board? Any assistance is much appreciated, thanks.

Hello.


I am struggling with EGT LED monitor. Panel is made from AUO.
I have 1/4 good and 3/4 bad pictures like you can see from the pic.

So far I checked power supply and it is ok. I cleaned connection from panel to LVDS and LVDS to digital board. No luck.


What is the problem with this LCD?

Pannel, LVDS or digital board. I have no idea so please help me someone.
