Hi Sorin, for the disabled wifi did you try a fresh clean bios? I often receive HP Probook from a company were safety is critical, they disabled wifi by custom bios, when they recyle them they left them as is. I replace Bios in order to gain camera, audio and wifi. In my case I know of course the story of the laptop.:)
There is often one pin on the WiFi card, which is working as hardware "wifi power off" switch. If you block that pin, the WiFi card will not disable itself. You can see the card in hardware, so card is working, but is "disabled" by hardware means. Search pin 20 and pin 51 on older cards...
@@laboratorioassembler - have to disagree, for example Mini PCIE Realtek 8821CE, pin 20 description - "pin 20 --- WL_DIS_N --- WLAN disable control". You can check datasheet yourself ;-). And "pin 47 --- BT_DIS_N --- BT disable control". For MB soldered Wifi, try to google "RL-EM02G-8821CE-V1.1" - pin 28 = "WL_DIS_N" and pin 63 = "BT_DIS_N"... For "Sorin's" card (Intel AX201) its the same pinout - pin 28 = WiFi kill switch, pin 63 = BT kill switch 🤷♂
@@commandroid9336 - thin transparent tape is enough. Cut it with scissors (yes, you must be precise, its thin stripe for one pin, but its worth it). Literally now I did this trick with one NGFF WiFi card on one HP Sprout PC. The same problem - WiFi card recognized, no error on driver, but cannot be enabled. And now its working great. I dont know if I can paste links here out of youtube...just google "How to mask off the wifi power off pins" - you will find several websites with different types of wifi card slots (M2, MiniPCIE, NGFF)... Good luck! ;)
Portege has settings in bios to turn on/off some things. Check web cam and wifi is enabled in bios. Or swap bios or do bios update to latest one using official Dynabook bios update software within Windows. Then go to bios, turn on cam and wifi in bios, install drivers and may be working.
Remark 43:55 - 48:53 : Sorin just waited for multiple restarts, multiple minutes, something that looked like dead device, then it just logged in. 53:57 - He spent 2 hrs fixing 5 chips and 5 boards, meanwhile I spent 8 hrs, changing 1 chip ok, and second chip change caused burning the board :D
Very good video! Some new stuff no way easy, thank you! No need to tell you we would like to see full two hours version. Maybe you could post full versions of videos for your die-hard fans and members together with edited version for general public which may like shorter content. For me, longer the video the better!!!😁
On older Thinkpads you need remember there is hardware level adjustments through example EC chip. It doesnt matter you try on linux or windows you wont hear sound if you dont use the keyboard sound buttons to unmute or adjust sound level. Hate it and or love it.
The board that worked could have different wifi and camera model or manufactor. I think if you would swap original BIOS on the working board, it would work. Also now customer can have different specs with this motherboard, like clockspeed or RAM , but at least he/she has a working laptop.😃. Good job Sorin.
Hi Sorin , and thanks for sharing your useful knowledge with us , i do find your videos entertaining and learning from your skills too. i do like to share a situation that i did found before which comes with the same issue or sometime both faults non of WiFi and webcam is working using windows 11 , tried to see if there is and kind of short circuit on the board and also tested the WiFi card if its communicating with PCH chip using oscilloscope and every thing looks fine but still no being able to enable them , tried to swap to a new SSD with a fresh Windows 10 and everything got to work just fine , i thought in the beginning that its a driver issue while using the old SSD with windows 11 so i did swap it again to the old one and tried to uninstall and reinstall clean drivers for it but no luck at all , so in my opinion its an issue with windows 11 , maybe somebody have the same issue as me and got solved ... Best Regards ..
For the webcam not working as it’s usb you can always find an internal disconnected usb or from a mini pcie if that’s what the wifi card uses, you could do that with the wifi too but that would look like a botched repair from inside
You can also try, for once, to swap the cpu/chipset from the most damage board (liquid damage) to one of the board with camera/wifi problem (chipset?).
After such hardware changes I think it's good to give it an Internet connection and lots of time to update. Go to lunch, go to bed, whatever. An Ethernet-USB adapter may be a good investment for these laptops with no RJ45 jack. That way you have no issues with WiFi connecting. You got a working laptop in the end. That's what matters. And that we learned!
If the camera driver wasn't installed maybe that's why the camera wasn't working on the other board that stated the camera was broken? I would test the SSD you installed the driver on the other board that said the camera was bad.
pretty much every toshiba I ever did with a wifi not working issue was down to the keyboard failing. the F key that turned wifi on/off gets stuck in the off and change keyboard turn wifi on and fixed.... tat goes right back to the old silver ones prestiges satelites all of them from 2006 onwards
Hey what temperature in C⁰ are you using to resolder the components with the heat gun. When I try to work with 320C⁰ the components desolder really slowly and sometimes I end up overheating the board.
For the Wi-Fi not working, I'm 99% sure it's a software issue. Either BIOS or a driver issue. I would try with an Ubuntu live to be sure and to know if it's a Windows problem or not. In my case a third party antivirus was blocking the Wi-Fi card even after it was uninstalled.
Sorin you never pluged the wifi cards in with the little wires my understanding the wifi card wont work unless you conect the wire clips the chip ?????ok you explained my question near the end good job well done that was hard
How did you get round recovery key problem? I thought if you move a window 11 os to another computer without retrieving the recovery key from Microsoft your pretty much buggered.
Hi everyone! In some soldering videos, I’ve seen a thing being used to protect components like electrolytic capacitors from heat when hot air is being used. It’s not Kapton tape; it’s more like a small metallic or cylindrical structure with a yellow transparent material on top (probably Kapton tape). Does anyone know what this is called or where I can buy it? Thanks for your help!
Hi dear sorin. You showed a laptop analizer software fom Romana guy which seem to be very good and useful about two years ago! So i want to know the total price fot that! Would you guide me how to can get his address or call phone number for buying one? Best luck
@ATAG-yn5pd If your Wi-Fi is not showing up on your Linux laptop, here are several steps you can take to troubleshoot and potentially fix the issue: 1. Check the Hardware Switch Physical Switch: Some laptops have a physical switch or function key (like Fn + a function key) to enable/disable Wi-Fi. Make sure it's turned on. 2. Check Wi-Fi Status Open a terminal and run: bash nmcli radio wifi This command will tell you if Wi-Fi is enabled. If it’s off, you can turn it on with: bash nmcli radio wifi on 3. Ensure Drivers are Installed Check if your Wi-Fi card is recognized: bash lspci | grep -i network If the card is listed but not working, you may need to install additional drivers. Depending on your Wi-Fi card, you might need to install proprietary drivers. Check your distribution's documentation on how to do this. 4. Update Your System Sometimes, simply updating your system can resolve driver issues. Run: bash sudo apt update sudo apt upgrade (For Debian-based systems like Ubuntu. Use the appropriate commands for your distribution.) 5. Check Network Manager Ensure that the Network Manager service is running: bash systemctl status NetworkManager If it’s not running, start it with: bash sudo systemctl start NetworkManager 6. Check for Disabled Wi-Fi Sometimes Wi-Fi can be disabled via software. Check the status with: bash rfkill list all If it shows that Wi-Fi is blocked, unblock it with: bash sudo rfkill unblock wifi 7. Reboot After making changes, a reboot can help in applying the settings. 8. Check Logs If Wi-Fi still doesn’t show, check the system logs for errors: bash dmesg | grep -i wifi or bash journalctl -xe | grep -i network 9. Consult Distribution Forums If you're still having trouble, consider checking forums or communities specific to your Linux distribution. They can often provide targeted advice.

Must be investigated on next coffee with Sorin!! 😁
You fixed the spare board then ,lol, I was looking for touchscreeen, Very good, Thanks Sorin!
We are happy with long videos ❤️❤️❤️
Great video, keep up the great work
That is an awesome repair. congrats
Really nice repair!!! I wish i had this kind of ratio, 1 out of 5 would be a great step ahead for me😅😅
Another legendary repair video Sorin. Now that flashing is a self diagnostic code, could give you some clues like ram error or something.
Never give up attitude is the base of Sorins Kingdom.

I am exhausted after watching that!
The flashing light motherboard, I suspected the onboard ram, expected to see a reflow of the memory chips.
Hello Master from Cambodia
If the camera driver wasn't installed maybe that's why the camera wasn't working on the other board that stated the camera was broken? I would test the SSD you installed the driver on the other board that said the camera was bad.
Hi SORIN
for wifi problems, first try a bios update in 90% cases it resolve the problem
Amazing job Sorin. No easy pizza this time!
sorin the magician
Is the repair cheaper than a regular or mini USB wifi dongle
Yes a wifi dongle would be cheaper fix but Sorin showing great process to fix the way customer wants..lol
pretty much every toshiba I ever did with a wifi not working issue was down to the keyboard failing. the F key that turned wifi on/off gets stuck in the off and change keyboard turn wifi on and fixed.... tat goes right back to the old silver ones prestiges satelites all of them from 2006 onwards
The fact yiu have so many spares for one laptop, show that this is a LAPTOP TO AVOID.
on point. bs and everything is soldered lol
Nice! 😎
You are the master for the electronic repair mate, most would have given up but you made it work!
Hey sorin,
Did you try to update the bios?
Or use mint linux from usb?16:22
Nice bro❤
What are specifically the terms and conditions and are they not necessary for advancing in repair attempt?
The longer, the better!
Hello 🤝Good Job I like long videos repairs 👍👍👍👍👍👏👏👏👏👏👏👋👋👋👋👋👋
Hey Sorin. I don't think the screen webcam was working. The one shown was the camera on the palmrest. I wonder what a palmrest camera is good for?
i think it folds all the way back like a tablet style and you get a rear camera
@commandroid9336 Clever! I don't think sorin checked the screen webcam.
@@mikeh6286 yes exactly its the bottom camera showing bottom of his hand idk how he missed that xD. Probably both still work not sure how to switch
Hey what temperature in C⁰ are you using to resolder the components with the heat gun. When I try to work with 320C⁰ the components desolder really slowly and sometimes I end up overheating the board.
I would swap the EC chip to the LED-flashing board.
At 14.08 time, there are some solder bridges, on the left side of the card.
no it is flux reflection
How many of these boards including the original had the same model of CPU?
PD controller issue possibly? on the green board possibly?
For the Wi-Fi not working, I'm 99% sure it's a software issue. Either BIOS or a driver issue. I would try with an Ubuntu live to be sure and to know if it's a Windows problem or not. In my case a third party antivirus was blocking the Wi-Fi card even after it was uninstalled.
he's trying the same ssd (same windows) and swap the board
it's working on the other board (same wifi chip)
Sorin you never pluged the wifi cards in with the little wires my understanding the wifi card wont work unless you conect the wire clips the chip ?????ok you explained my question near the end good job well done that was hard
Those wires are antennas. Just for signal, wifi still works and should turn on regardless
For me the not starting board.. in weird way can be soldered ram.. no?
That was my thought too, like usually... bios, ram, anything else
Thank you Lewis
I learn new repair tips from you every day 🙏
Don't be tired
I'm pretty sure his name is Steven
@@bluecup25But wait his name is Lars?
lol you guys
How did you get round recovery key problem?
I thought if you move a window 11 os to another computer without retrieving the recovery key from Microsoft your pretty much buggered.
First time I see a wifi card soldered to a motherboard 🤣😂
what did you say after Hello ?
Can a corrupted file in the bios switch off the wifi? Or maybe even a hacker.
Hi everyone! In some soldering videos, I’ve seen a thing being used to protect components like electrolytic capacitors from heat when hot air is being used. It’s not Kapton tape; it’s more like a small metallic or cylindrical structure with a yellow transparent material on top (probably Kapton tape).

Are you talking about high temperature Teflon tape? That usually is used on sealers? They work on boards as well.
You can make it out of soda can . Main think is to slow down heat transfer to those caps not to overheat them..
antena for receiver n transmit
Just extract the definition from the wif.. installation program...and install the definition only...good luck
First i check from bios or keyboard maybe wifi is off by keyboard of maybe in bios😅 then only i do these replace thingi
How can the coils be ok if there is no beep and 0 ohms????
beep happens when there is low resistance. So no beep and 0 ohms is impossible unless multimeter beeper is cooked
nice...
Hi dear sorin.
You showed a laptop analizer software fom Romana guy which seem to be very good and useful about two years ago!
So i want to know the total price fot that!
Would you guide me how to can get his address or call phone number for buying one?
Best luck
Sorin: Windows update bad for computer
Also Sorin 0.00001 miliseconds later: Windows update good for computer
How can i learn repair laptops and fix the motherboard pls
Watch all his videos and practice practice but you do need the correct tools
👍👍👌👌
It's a bios issue, must activate wifi there.
Nope
You know it's bad luck when you see everything is soldered to the board
I think its not hardware but new windows on old laptop looks like driver problems
...puteai folosi programatorul pentru a clona firmware-ul. era mai ”curat” și aveai un back-up
Nici n-ai verificat Driverele după ce ai schimbat wifi modulul . …
SO WHAT DID WE LEARN TODAY? keep swapping till you get lucky?
Must find a W11 driver
a wifi usb adapter for the first card will solve all the prob.
Je dobré WiFi pouze například Windows 7,8,... Starší driver. Windows 11 not driver musí manuál driver stahuj.
