Your bootable usb must have the MBR sector table and not GPT otherwise would have booted no problem
Can you fix 2017 iMac motherboard with vertical lines
@@stocktronics sounds like a gpu issue
@@justins4932 is gpu is the same as the video card ?
@@stocktronics Yes!
I had the initial symptoms again with Ubuntu, my problem was Ubuntu wouldn’t run on my SSD as a GPT and I had to reset it as a MBR on a second machine. That worked for me in my case, but I feel like Grasshopper telling his blind master how to walk on rice paper (ask Big Boss).
Today I retired from a job I loved but through my health problems I knew it was time. I understood every word you said about loving your work and time flying. Enjoy your work, but if I’d understood the work life balance I might never have become disabled in the first place.
I'm from the future. You sir are a professional and have come along away felling at home in front of the camera making good content for us. Take you very much 🤜🤛
That was the best answer to provide to that question of "How can you sit down for hours doing the same thing?" - Your job is amazing and the passion and commitment with problems and clients is the best I see from far.
A nice way to keep the screws in is to lose them up, so they would fall out and then put some tape above the hole. That way, you never lose them or get the wrong screw into the wrong hole.
I do that for years now and when you put it together, your screwdriver just punctures the tape and you can screw it together, remove the tapes and your golden.
Great idea
Thanks
Great tip, thanks
Blessed is the man who loves his work. It is very obvious that you are good at what you do and enjoys the craft itself and is proud and competent in his vocation. Not many can say this.
I enjoy the videos when the repairman talks about himself. Gives you an idea of what it takes to be a good tech.
You do smile every time a fix works - best bit of your videos
Watching this in 2021 and its amazing how far you've come 👌
It's true. There are some technicians that do not care on organizing screws and sometimes just put things back in "as long as they fit" mode. There's no smoothness in those kind of work.
Thanks for your videos, and also with some thoughts you share.
To my knowledge, it was a bad programmed UEFI variable handling by Lenovo's BIOS implementation. The kernel did it right, Lenovo messed it up. ;o)
They say “if “If You Love What You Do for a living then You’ll Never Work A Day In Your Life.”
Love towards ur work is ur patients 👍🏻👌🏻🙏🏻.stay fit and healthy.
LOVE THE WORK YOU DO THIS IS WHAT I DO AS MY JOB LOVE EVERY MIN OF IT AND WOULDN'T CHANGE IT FOR THE WORLD
How do you find the right chip? or the or the components need to be replaced. This is my hobby but I haven't started such repairs yet, I'm still learning the soldering part.
i got lenovo g5070, and got same issue. i left my laptop in support center and after several minutes they sent an e-mail: "MB is broken!". i thought that they do not know what to do and i was right. they said double of the price of Laptop. and I told them it is impossible to be true. I mean MB ..!? any way they wanted me to pay service fee and take Laptop back because they got nothing to do. It is hard to find professionals nowadays, and people who loves to do the job.
thanks for sharing, grate job
im from phil, bcoz of u sir i manage to repair motherboard now got to 20 or more coz of u thank to u and god, god bless u sir
am industrial control engineer i thinkn
its time to switch to your job. i love it.
Turn off secure boot. It should be under security in the bios. Then you can run unsigned boot partitions
Doesn't matter what your study background, matter is You're a good heart man.
Wow looks so much different now! These old videos were still good
I started almost same as you. Started helping dads friend wire houses when i was 8. Read lots of books and by 16 had designed and built a cctv camera. By 18 designed and built a pc. Then uni. Got a degree in microelectronics and computer design.
As a technical question; how is a normal installation of Ubuntu reprogramming the bios? Sounds like the user may have used an ubuntu that had a virus of some sort.
Ubuntu modifies the uefi bios to install its Boot entry. In the early stages of uefi due to mismatches in the specifications / bugs in the uefi implementations Linux could brick the uefi bios of some vendors.
Nowadays this shouldn't be a problem anymore.
What about a BIOS flash restore before disassembling the entire machine?
I don't think that would be possible once the chip has been corrupted. I'm sure he thought about it too.
It could be done potentially with a bios flasher it clips directly onto the chip with a clamp lead and can flash the chip. Depends on if there was hardware damage to the chip
@@TopherToke Yes, I guess he didn't know bios chips could be flashed this way.
No flash options in the bios+it is not recognised the flash drive.
@@83Sogron huh? Isn’t it an external kit that clicks onto the chip to reprogram it?
That usually happens when secure boot is enabled. You need to turn it off before booting Linux on legacy. Grub should have came up, but it didn’t, so either secure boot is on or grub is broken.
You need to run an actual boot rescue, not a bootable USB. This will fix these issues 99% of the time. If it was the bios chip, you wouldn’t get a bios menu.
No. It was a bug in Ubuntu 17.10 that would corrupt the BIOS on some Lenovo laptops. That's what you get for using ghetto operating systems.
@@comicsanz97 thanks lol that actually proved my second comment right lol uefi with no .efi 😂
You one hell of a genius.well done , the great thing with u is that u got every tool as an extension of ur brain. Love watching ur videos.
Hello, love your videos, And am learning alot from watching your youtube videos. You are a soldering god to me. I have learned in my trials , you can make a bootable EUIF drive. you have to perform this as a GRUB drive and not as a MBR drive. Just my 2 cents. But it will see the USB drive once you create using GRUB and not as MBR. You are very talented sir. Keep rocking.
Love to be your student 👨🎓 from Sydney. I do normal laptop and phone repairing as a hobby but I try to fix all kinds of electronics as u are doing. Just because of u I manage to fix one of Bose subwoofer 700 which never turn on. Finally I fix it with my own here n there experience 🥸. But I have a passion to do this kind of jobs. But I don’t have any education regarding electronics at all. I did my MBA in management information systems from Pakistan but after 10 years my mind start understanding all type of electronics… I have no idea how it’s possible but I feel I can do this kind of jobs easily but I need guidance like u providing through your excellent videos. I learn a lot … kindly suggest me some short course so I can further excel in this field of electronics. Highly appreciated… thanks in advance.
Love how you talk and of course the job you do.SUPER!
since a high school i like to open some electronic in my house. and now that im graduate from high school im planning to to take electrical engineering for my college and from your story i already know where im going to end up. and im hoping it will
love your vids btw its fun learning new things
14:02 it's a common question and my answer is the same as yours, sometimes i came at 6-7am in the morning and the time simply fly away because i do what i love to do, at my ex work place a day passed too slow because of a annoying boss i didn't loved what i did and i didn't know how to make time pass more faster to go home at 6pm, now when i'm working for myself the time fly away like you said it's feeling like an hour😊
you did not try to change the IDE. to AHCI in bios?
Often it helps from experience.
often a computerhas and bios recovery mode!
yes the video is from 2018 I know
I love your videos. And appreciate your believe to be honest and do things right no matter what. May God truly bless you. Your videos is helpful and inspiring to me. Thank you for being who you are. And keep up the videos and great work. All the way from South Africa 🇿🇦.
Great repair!! You looked so young in this video..
Alex what is it about this board and chip that made you decide to use low melt? Could it be not disturbing components around the BIOS chip? Your channel is awesome BTW. I recently decided to switch from the automotive repair field to Endoscopy service after 30 years of busted knuckles and dirty hands. Your channel has taught me so much about electronics repair. You inspire me to get into electronics repair on my own. You are very gifted in doing what you do!! My micro soldering has improved very much in the past 2 years. I recently opened up a USB I had soldered when I started my new job and was embarrassed by what I had done.
Did I like the video? You asked.
I loved the video!
You are a good bloke 👍.
Love what you do and the time surely flies easy !
respect,I like your channel and your job,God bless you.
So you from NY..me too .Brook Poly is a great college..it's in downtown Brooklyn.
I miss the old times when you could easily replace a PROM in a socket.......
Did laptops have these sockets? I never changed it when I was young, laptops were to expensive for that. Co.puters had them and hell we needed them 🤣
Hi!
The old chip bios become good by programming in a programmer?In my case if I will take out the old bios chip and reprogramming and put it back, works?
You are the best!
Thank You!
If the customer flashed a wrong bios then you can reuse the old chip, but if the old bios chip became corrupted without doing anything, you need to buy a new chip and program it if it isn't already
By the way, desoldering-soldering is not needed, because there are special clips to program in-place.
@@gio0042 Thank you!
What I do to solder the bios back is to add solder to the pads first and heat it up then put the chip on top, then I come with the soldering Iron and flux to make it cleaner
What a waste of time. I have the same laptop running Linux Mint (Ubuntu based), and yes it will not boot from the USB on EFI mode, unless I physically remove the SSD. Another option is to enable legacy support and then reboot into bios again. Then it will show the legacy boot options.
@@danielsatko- I can only see what is shown in the video, and it is exactly what my laptop does. Also this laptop has a recovery button (NOVO Button).
Easier way is to convert the USB from MBR to GPT. And then use it to boot the OS you want that supports GPT
So your from NY..me too . Brooklyn Poly Tech is a great college..it's in downtown Brooklyn.
you failed to check to see if Secured Boot was enabled. That is probably why it didn't see any BIOS "Legacy" bootable Devices because Secure Boot was probably enabled.
I used to repair early laptops , also fixing electronics having learned from taking thing to pieces in my younger days.
3:55 when your computer booting sounds like a car
@NorthridgeFix I had a similar issue similar hardware. The system probably would have booted a Linux USB but not Windows as you tried. I fixed mine by deleting all trusted keys, cold resetting the bios ( cmos & batt unplugged, drain power by holding power button for 20 secs ), turn off secure boot and the trick is to hot switch the windows live usb when in bios boot drive selection. Try to use a USB2 port if possible.
Great job again like always
Bro really i not understan what happen to the BIOS. Pls explain why this happen. what are the posiblities
Sometimes you need to set a password as administrator and then it allows you to change the list of uefi bootable devices.
You are awesome in trouble shooting, please make how trace problems in any mobile phone a video
did u bought new bios or just a chip and you flash it ?
We never know.
@FelinoFacho it is a compatible chip. Both are 25 VERSION AND 64MB memory type (GIGABYTE 25b64bsig vs winbond 25q64fvsig)
@FelinoFacho that.. for me it is new. and the ic was flashed out of the camera.but that is for me. i prefer to used a new one then a used. may have problems in a future with a used one.
You didn’t program the bios chip when you swapped it with a new one? I thought you had to do that so the system will boot? Never knew if I buy a new chip it comes programmed already.....
Just watched this video. I didn't know that Alex also fix software issues.
Great job and great dedication ❤️..god bless
nice new camera setup !
you know a lot of things Alex you are amazing
do you replace the cmos chips with others one ? nice one Northridgefix same idea here ;)
You never tried the dvd portable windows and bios recovery. If the portable windows boot from it since it was detected from the BIOS then you can flash the bios inside it. I don't know if g7 has a bios recovery mode but most modern laptop has it.
the same problem happened to my motherboard. i was surprised by the fact that an os can overwrite the bios
Another fantastic video / weill done / thanks for sharing
I really like your videos. Good job man, keep it up.
You changed the BIOS chip and not the same # and it works - that tells me something - any BIOS chip replaces the old one ???????????????
enjoyed watching experts getting their hand dirty on the motherboard.
thanks for the informative video
If you have a problem with screws, put them away in the proper order, and reverse the order when assembly the device - works like a charm :).
Lovely job. You are my inspiration.
Is this the same shop?The enviroment look difffrent than the latest vid👀
hi am late to this video but if i am stripping a strange laptop i slacken all the screws and put a piece of masking over each screw to keep it in it's right place
Key combo for nvram reset would’ve likely got you up and running without dumping the rom and editing yourself.
The original problem could have been something related to Secure Boot / TPM
nice one sir really enjoy this one but i have one question to ask can i remove a bois chip from a working laptop and put in a corupted one?
you should have been able to reflash or jtag that chip, not criticizing, great video
Have seen this before.... it looks like its a DMI problem....
the new bios chip is programmed already?
I'm also interested in this question
how did you learn this job I mean that repairing.... Tell me.... I m very interested to know your experience
How to identify bios chip in any laptop
Should be a 8pin chip
I had lenovo y50-70 and it had similar issue. BIOS was not applying changes multiple hours and restarts later I found out it had some weird issue that only complete power off was correctly applying all changes (had newest bios at that time). Maybe this helps someone.
I think the BIOS was ok just stuck in first-reboot posinstallation
maybe FIRST try another harddrive with a good GRUB
or reinstalling the GRUB in the harddrive from another PC
and sometimes windows leaves the hard drive suspended for fast reboot and gets stuck or you can't access or edit documents in patitions .Desactivate the fast reboot in widows energy manager
Thanks for your insightful video as always. One question to ask. Where can we get/buy a healthy BIOS chip? I have lenovo ideapad520 that now seems to have the same type of currupted BIOS on it. It boots up, but gets stuck with black screen never allowing me to enter BIOS or recovery mode. Before becoming this, I tried to update BIOS via official lenovo updater running on Windows10, but the last stage of updating process, my ideapad suddenly got frozen. Now I desperately need to get the healthy BIOS chip and replace with currupted one. Any info is appreciated.
There's no excuse for Ubuntu doing that. Did Canonical learn their lesson after that? How many did this turn off of Linux?
Turned me off, I'm a student who's laptop is already dead I can't afford such disaster.
@@therealb888 Exactly. I hope this is the only time a Linux distribution tries that crap.
@@infopackrat agreed, can’t imagine Linux going the windows route.
They disabled the possibility to flash the BIOS by Linux since 17.10. Don't know about the actual fix.
@@therealb888 Lenovo is now selling laptops with Linux preinstalled.
So I think the OS had very little to do with the issue.
Awesome clean work.
wonder if having turned off "PXE boot to LAN" would have "bypassed" the IPv4 error the laptop got stuck on would have helped before replacing the BIOS altogether
I was thinking , why not update bios from flash option ???
May be that also you tried already ?
I'm into hardware not so much software.......how the hell does a OS even have access to the BIOS like that?
Bios is a software on a chip, it can be updated, in various ways... also easy to get corrupted too... something crashes during update, bios can be caput if no backup bios exist laptop became 1st stage brick unless you replace the chip...
i would first try resetting bios settings on the cmos first... before chip replacement, sometimes settings on cmos (where bios settings are stored) gets corrupted, cmos reset can fix it sometimes...
@@mytester6208 For my own edification, I was wondering about this - I didn't hear it mentioned, but there are two easy steps before replacing the IC: reset the BIOS to factory defaults (sometimes called "optimized settings"). Except for the bootloader portion, everything else about the BIOS appeared to function properly. If a factory reset failed, re-flash the firmware through the BIOS utility? One of those two steps should have cleared out the BIOS eeprom/nvram. If those failed, yeah, replace the chip. Maybe they did those other things. Felt like they went straight from "I installed ubuntu, BIOS corrupted" to "replace hardware"
Hello!
My brother used my computer and spamed space button and electicity went out and its not working enymore it got no power what can u do to trobl shoot it? Bicose i dont have money to fix it in some shop.
How the laptop can run properly when the SPI (bios chip) not programmed?
Sir I am also love this work i have also experience 2 year of work
Ubuntu does NOT write to the BIOS! Nore does any other Linux distro for that matter!
Very good experience to now
i installed some kernel and it fixed the issue
Sir, ONE QUESTION - for desktop motherboard, do we need to replace with exact same BIOS model?
Thanks!
Awesome job 👍
Good job 👍
That computer would not boot any color of Windows. A differnet Ubuntu Kernel might boot, though, and once Ubuntu is running you can apply a fix.
Wish you showed the chip programmer .
so ubuntu damaged the lenovo laptop?
Yes, check bugs.launchpad.net/ubuntu/+source/linux/+bug/1734147
@@NorthridgeFix I use Ubuntu for more than 6 years, I look at Gigabyte cips involved with fear. Lesson is ....do not update too quick Linux, use a LTS.
I booted into bios and restored it to default. That seemed to solve my issue. (Ubuntu dual boot).
Good work.
