Huawei MateBook D14 no picture, restarting - What did i said about bios issues? :D 

I like it when he looks at a laptop and says "this is a nice laptop".

It feels good when your hunch is right. Job well done. Thank you for sharing.

Sorin, it would be nice if you can make a complete video about bios programming, specially about DELL, that needs many things like service tag and etc..

Hi Sorin Great video just for future reference the bitlocker key is stored in the TPM chip and a folder on the HD/SSD and not in the BIOS.

Interesting and entertaining, Thank you Mr. Sorin.

@electronicsrepairschool Sorin one thing to check will be the port. Under Ports in the device manager check that the BPS is set high for example 115200 or greater as the mismatch to the device can result in this failure. Also unde the Advaned Tab is set to high on both and that you are using a unique COM port and its not being interfered with by the USB hub. Its best to use a dedicated clean usb controller. I personally have had these issues due to this with various programmers and readers.

Sorin you should not program the chip on clip with so long wires with REVELROG. It should be in adapter or you should decrease programming speed. Generally you should use clip only for onboard programming. You have this in manual, I had similar case. It's to fast for so long wires, you can decrease speed in settings to 10% but it not always will help (10% is still fast for so long wires without any decoupling on chip side). When you desolder the chip, the adapter is only recommended solution and it will work.

5:34 no problem, sorin is now well equipped! ☺☺

Just like I expected I trust ur judgment when it comes to laptops repair sir.

Yay! Sorin got to use his new tool again!😁

Sorin got a new toy 😂. I feel the joy 🎉🎉🎉

🎉 felicitaciones desde Chile, tengo el mismo problema y gracias a ti ya se cómo solucionarlo. 😅

Good job mate 👍

Yes Mr Sorin I have 3 programmer the RT908H ,EZ2010 and the CH431a modded 3,3v . The CH431a reads some chips that others can t read .

Very Good Dear Sorin

Thanks Sorin.

I'm expecting Sorin to flash the bios in all laptops as standard from here on in 😉

Sorin I like the video like always And this was interesting. And use the old bios reader that’s Strange 😢but working. Thanks for update me

Im still learning; why do you use the red probe on the ground and the black probe on the component to check the voltage? I was thinking it was always the other way around.. Many thanks and great videos

On newer laptops that don’t have dedicated BIOS batteries, this is a common issue. The issue usually pops up when the lithium battery starts to fail. Eventually, the BIOS gets corrupt. In most cases, you’re better off, swapping with a completely new chip.

With the bios files don't the motherboard manufacturers have the bios for download ie the same one they provide on their website if there is a newer bios for updates? Can you use the same files?

Thank you for the heads up on the 1.8v module for the ch341a - it never came with mine and no instructions to make me aware of it.

Many thanks, but from where you download BIOS backup?

From where u are getting the bios bin for any laptop ?

my Intel NUC mini pc has same symptoms- no screen at turn on. i’m thinking mybe corrupt bios chip too. (i have no experience servicing pcs.) all the motherboard voltages & currents appear normal. (a hardware issue on hdmi seems less likely). while i will probably write it off, your vid inspired me to try to fix just for learning experience. will do further research on upgrading bios.

hi there, the motherboard on my matebook d14 is dead. do you know if i can change the motherboard from bob wah9 with Bob wah9q. i cant find what's the difference in that one letter q at the end.

Sorin, I need to change a 'MEC1404-NU' IO chip on a Dell. How do you know if it needs to be programmed?

i am right now having a simmilar issues with my moms matebook 14, where the screen wont really work, but i have via an external monitor gotten into the bios and Recovery mode, but after that it just goes to black, my 2 theories is either something to do with the onboard ram, or ir has something to do with the graphics prossecor in the CPU

Merhaba, Huawei biosunu nereden buldunuz? Benim aynı cihaz var ve modeli. NbB-WAH9 ama biosunu bulamıyorum.

Windows 10/11 like to upgrade firmware like optional update. So it something happens during that process it kills the laptop. I have few cases like that on laptops and desktop boards.

I have the same problem. But since my laptop started up with some attempt, I managed to update the firmware from Windows. The problem disappeared, but after half a year it appeared again. What do you think could be the cause of bios damage? (Sorry for my English, translated with Google)

hello master, I installed intersil 95859C HRTZ X908FFQ instead of intersil 95859A HRTZ W638EZ8, it didn't work, I don't have a GL signal in the mosfet, I've been dealing with it for 2 weeks, please help

I have a Huawei Mate 14 laptop but it turns on normally and everything is fine but it does not detect the m2 ssd device. It is connected to the slot but the bios does not detect it and the ssd unit is in good condition. Will it be possible to reinstall the bios without the SSD? Or do you know an indication of the problem? It simply stopped detecting it after normal use it no longer detected the m2 ssd device

Hi Sorin, I have a problem with a Huawei laptop that doesn't start, it's definitely a bios problem. Where do you find the files to put on the flash? thanks in advance, and happy holidays

hello,where to buy a keyboard for huawei? this model exactly!

Caps and Fn Button lights are turning on when you press the power button

this kind of issue in the bios is known for Lenovo, but I didn't expect to see it in huawei, I work as a local IT and we used to give lenovo to the users they always return it with boot power or post issue and it's 85% coming from the bios either we force an old bios version or send the computer to the lenovo, and once we sent more than 10 laptops after a windows update that updated the bios and we couldn't flash new or old bios Now we are using HP laptop since january no bios issue so far

I got same model,its only turning on if i disconnect the battery and use only the power brick,when i attached back the battery it wont turn on,what exactly happened?

😶 I guess u really know your stuff to be videoing while working. Forget if these things don't work. These things r highly complicated. 😄 i actually like your work. Everything shows how real u r. I subscribed. 😳 If it was really software that caused the entire screen not to work then i was really right. 😑 Too complicated

Why does discord says that invoice is invalid ?

CAPS light did turn on and the FN key light turned on. Hard to notice sometimes. :D

Some desktop mother board now a days has dual bios. But I have not seen it in laptops yet.

How it connected to your wifi network?You just fixed it!!

Good day Mr. Sorin, Can you please send me the link where I can download a working BIOS Bin file for this unit, thank you and more power to you

Danke

I have the same laptop still working very fine, I am thinking, how does a BIOS get corrupted, due to an operating error or a sudden shutdown ? And is it possible to flash a bioschip when it is soldered on the board ?

How about rt809h programmer ?, i heard it's good

Can you share BIOS dump on latest versión please?

i have a same motherboard with exactly the same problem. it came to me saying the bios flashed manually and it was keep crashing when loading windows unless i make changes in bios in every restart. so i decided to update the bios and it bricked after i updated the bios using official v1.18 updater. does anyone know how to recover the bios without messing with desoldering the bios chip?

Hello, you need an adapter, the clip doesn't work every time especially in the circuit.

the fastest bios programmer is a Raspbery PI - it has a hw SPI which reliably runs on high clock speeds. flashrom command line utility supports most of the SPI bios chips and it's lightning fast (on high clock speeds). it runs 3.3V natively and you can use an adapter for the 1.8V chips.

Where are you working on 2 different laptops? At 9:40 the laptop changes from silver to black, and the stickers change on the lower right corner

It looks like BIOS issue has become very common recently. Is this due to the chip manufacturers are currently using? Or something else?

please, how can i get Huawei bios

Hi sorin please do us a biginer course for mobile phone like that of laptops

Bios issue is really annoying, I have difficulties with ch43

where can i get firmware

My huawei laptop kinda experienced the same thing, no display but it turns on and caps lock and fn key stays lit. Got a main board replacement. Still waiting to have it back Now I wanna know what causes this? I was just using my laptop when it suddenly died and never turn back on. I'm afraid it happens again. Will replacing the entire main board solve this and it will not be broken again?

IMO super fast speeds with these hacky setups can cause repeatable errors (means verifying will pass), so I wouldn't prise that factor.

Hi Sorin why you did not fix the original dump. Or let it fix on discord. Probably clean me region or replacing bios region in the dump.

I own the same laptop and every time you power it on the keyboard lights up automatically for a second or two then the caps key and fn key stay on until it boots up successfully if not then it reboots for like 4 times before it turns off completely but you can force shutdown by holding the power button.

Do have a bios file?

Now you can optimize that Revelprog programmer and make a video. Shorter wires, shielded wires. What works, what doesn't...

Please show us how you make bios file and extracting from exe

my lenovo ideabook S540 nvme not detect pls tell me any solution i m from india

same problem but i dont know how to do it 🥺

I have the exact same issue. Seems like its a common problem with this model

Bos bolehkah minta file biosnya

When there are reasons to suspect of bios corruption, a hard reset may save us a lot of time and effort.

I got same error once when Windows update pushed bios into my machine and bricked it

Sorin how can i immigrate to uk from Iran and do something like you

At start of the video: laptop is powering on, it has two leds showing that, on Caps lock and FN... Only Sorin not seeing 😅

I think my ASUS laptop has the same problem. Can I use the bios reprogramer without desoldering the bios? What's the name of the software used with CH341a and the 1.8 accessory?

Should have tried to clean me region.

There is a little grammar issue in this title, can you find it? (or in my spelling or grammar for that matter??).

Sorin! you should have NOT reset the TPM ;(

What is the cause of BIOS failures????

T-56 would have been better buy.

Sorin changed behaviour for some reason.

very nice .

LOL the cpu is hot got me 😂

Press the camera button for a surprise

Rule #1 for beginner e-repair man: 1. Upon opening a laptop, flash new BIOS

You should never say Huawei and nice in the same sentence.

how can bios be corrupted like that?

do you repair for free next time bios goes ? simply re writing bios is not fixing it , it will loose bios again . its like pumping up car tyre with slow leak . this is not fixing laptop . just temp repair .
