As the owner of this Dell laptop I would like to extend my gratitude and thanks to Sorin for having the skill and knowledge to be able to bring it back to life. You are a true professional in what you do. I hope others find this video to be as interesting and informative as I did.
Is it only 2 or 3 years old?
Kind of sad that it fails like this.
Maybe 3 year old
@@martinwdesign Those Dell Precision mobile workstations usually comes with a 3years Next Business Day warranty...
I can bet the warranty just expired, right?
definitely out of warranty
even thou the cpu is a little lower but surprisingly it has a mxm dedicated gpu
You can set the Service Tag in BIOS. You need to enter bios and under service tag. You can finde the service tag in the old bios or under the Backcover. Also on Dell page.
Nice Work.
That's great, but same as with the xps we need more details on the bios cooking process. It's weird that service tag hasn't been asked and they are only asking random numbers from board. Please check you original bin file with the one they fixed and find out what changed. You only need a hex editor program to compare files.
he's a great technicien, he knew the exact problem instantly , big respect, i realy enjoy watching him and i learn alot from him
As an ex Dell warranty engineer, we used to have a bootable dos CD with the flash tool on it. Latitude and Inspiron boards were the same but we just flashed the replacement board with the correct BIOS and then use the service tag util to re-input the service tag.
Thank you for sharing. I have been doing bios repair for a number years now mainly for family and friends. I am still learning and it's quite difficult to find certain manufacturers bios on line.I have learned from forums and other utubers like you and the like of NSC and others. Keep the good work and you are amazing.
It's just like I told you on the last live session chat... Those BIOS faults are not new, they've been there for many years before... and quite frequent on all Dell laptops, not only XPS and Precision, but also Inspiron and Vostro alike. Seen so many cases before, even under warranty, and strangely enough, Dell service usually chooses to replace the motherboards entirely when this happens (if it's a warranty case) or deem a no-fix outside of warranty...
Crazy, I know, but that's the situation unfortunately...
The key point here is they deliberately made reprogramming the BIOS/UEFI so complicated, so ppl will somehow be forced to take their official advice and buy another new mobo instead. Pretty much the same Apple does, knowing it's an expensive device, so ppl will not abandon them easily...
@@silvake No they didn't. And, It's not very complicated.
Great video Sorin. Your skill and experience saved an expensive laptop from oblivion.
I don't know how much you would charge for this, but it was worth it!
Hardware & Software go hand in hand today (together). Personally, I feel that I am several steps behind in this field (software for current laptops) but if I acquire the appropriate programmers accompanied by their operation manual with well-detailed instructions to handle them, I could familiarize myself (I remember with nostalgia the manuals for oscilloscopes, digital multimeters, etc. ., from the old days).
On the other hand, excellent intuition and analysis to solve this high quality device and for that very reason of its cost. Thank you very much for sharing. All the best.
That is awesome! Great to see the community on discord helping out with the bios chip to program it, nice.
Thanks a lot., i always watch your tutorial to improve my skills,, from philippines😊😊
im excited to sorin going on a path to learn software side bios fixes, im inspired as you should always learn and adapt and never let youself or others tell you otherwise.
I'm liking all the bios/firmware videos 😊
Can't believe you are able to pull the bios chip and repair it. What a technician!
I have huge respect sorin, the fact that you try to improve your skill, see everything in repair as a challange and try to actually repair it the cool way and not only replace
your videos are like a proper nice🤌netflix series for me
I do find this kind of stuff interesting, but now I mostly watch just because I like watching sorin do his thing
Learn and teach us. best teacher ever
Hello thank you for the videos sir. Please keep them coming thanks.
Great Video Sorin enjoy your videos.
If I can suggest... the "badcaps" community is very active and usually some "veteran" can cook a bios and share it with anyone on the forum... also original dumps are very welcome ( just remove the windows key before posting it on the forum)
The most interesting part for me personally is to find out what is actually causing data in bios chip to become corrupt!? This was never an issue with the older laptops. I can only guess that this has something to do with the process of production of the chips. Please share your thoughts! Thanks for another interesting video!
Older BIOSes (non UEFI) could also become corrupted but I think now they are getting so big and complicated, there are simply more points of possible failure. Add to that the relatively new business of Windows Updates updating BIOS (and other firmware) without asking is also another possible failure point. All it takes is an impatient person to forcibly power off their laptop even if the message on the screen says not to.
Thank you
Sorin is Genius as always!
Glad You could fix it. Laptops are way more complicated to Fix but you made it look easy . 😊
Another video, thanks sorin
Great video, I would like to know what equipment is necessary for such ''bios repair' jobs. Is there one kind of programmer, or multiple for different kind of chips, where to buy them, the best places to get the bios-bins etc.
Great repair! i use POGOpin to flash bios without desoldering WSON chip!
Do you have a link to aliexpress to a wson8 pogopin ?
Dealing with BIOS corruption will be more easy if first you try recovery methods.
Long time ago was so called bootblock that can recover BIOS from image on floppy CD or HDD when triggered
These days there are still methods to do that on UEFI , but every vendor implement it different.
You need to have BIOS recovery file or stock BIOS image file on some media, on right path, then trigger recovery mode by some key press at startup or some other things required.
If works then you don't need to deal with recovering serials,service tags, mac address etc.
Don't know for newer models but if memory doesn't trick me on HP's was Win+B pressed when powering up and files must be on predefined path. On Dell's was keeping pressed Del and insert charger (no battery) or Ctrl+Esc
good job
Those SOIC8 clips and cheapass CH341 programmers sure have saved a lot of time with laptops, only once had to replace the whole chip thanks to some weird EC/BIOS security stuff in zbook g5
Watching Sie-Tech a lot beside your channel who covered such kinds of fixes a lot in the past. Bios problems, caused by failed updates through Windows, seem to be very common on laptops these days. I guess once you now how to create the bios files yourself it can be a good business, even b2b.
maybe it has something to do with lower version of windows probably since i always reformat laptops for customer and always going for newer version. what ive always see is on dell,hp is that when you windows update is fetches firmware update and automatically apply it on after windos os update, but on other budget laptops like acer firmware updates can be only updated via manual or hidden in optional windows update. but some old hp / dell model they dont force firmware/bios update and like acer ones they too or windows hid it to optional updates but not all.
There must be a tool for DELL and HP as well to insert such info as service number and serial number even product number that can be provided by the sticker stickled on cover
as i know the service number is a combination or a calculation of the manufacturing date printed on sticker
thank you Sorin and love your videos they are always helpful
you are a true school
Hi Sorin
I know you have the SAS Vertyanov programmer and not sure if you know it has the ability to read and program SPI chips which is much faster than the CH341A, Nice work.
what is the tool you used for reading the bios chip and programing it?
i have a similar one....use usual charging port, not the Usb C/Thunderbolt for charging!!...otherwise u will pay a big prize in the future!
next tip: try to find the option of "automatic bios update"...it will a big issue, if something goes wrong! just never flash a Bios chip without purpose!
Never change a running system!
Is there no way to force a bios recovery? I think you press esc and control on power
The service tag you can enter yourself in bios settings.
Yeah same here... looks like many many repairs going tru bios repairs. crazy
I worked at Dell as a support professional, the service tag number jtag is a number that we ask the customer if they call so we can see if there is still guarantee or not, we verify the name, adres ect. We also see which laptop it is and we can see how to troubleshoot that specific laptop. If it can't be solved by Phone and the laptop is still under guarantee then we sent a mecanic with for example a New motherboard and all the hardware needed to fix the problem. If a jtag number is not present the laptop still works fine there is no speed limit, the only thing you can't do is call support
thank u !
I hate were we come with 10 years, laptops become much more program dependable, and much more problematic in repair. Ones you could reprogram BIOS within a board, and this was the same BOIS, now it is SMD and have to be reprogramed for every motherboard separately
sir sorin You Should Clean Bios Me Region this might fix error at the startup . Use ME Analizer tool Just Drag and Drop your file to see what bios your usuing. I think your bios file is in initialized mode{here monufactor edit serial number to the laptop bios and other stuff }. you have to convert it to configured mode. this will fix all.
Agreed, my wife's DELL has an intermittent fault with the charger - an original one. I don't know the value of the resistor in the plug, so, I didn't fix it ;). And, from time to time can be slower just because of that issue.
Where did you get the gyroscopic screwdriver, I tried looking at the Amazon list and your forum page though can't find it I'm in the USA btw
What if you just got another mother board, Would you have to change anything in the bios when using the old hard drive? Thank you
Hi Sorin, I've been following you for a while and I really enjoyed watching your videos. Recently my Dell laptop has the same issue that it won't start. When I press the power button, the keyboard light is on but nothing else. I did check the temperature of the CPU and chipset, they seem to be warm. I checked the main power, it's fine, the battery can be charged as well. One strange thing is that, the CPU gets warm even when I didn't press the power button. Is there any possibility that my BIOS also got some problem?
Does the fan spin when the power button pressed ???
Hi Sorin what is the name of Flux using?
Hello I wanted to ask you how you managed to solve long screen post problem I had the same device and when I programmed the bios and entering service tag etc when I shutdown and try to turn on it take like 2 min to show anything on screen and I did try another 2 or 3 bin files with same problem
This one is an expensive laptop, i guess the repairing charge will be more than usual laptop. BTW great video 👍
I'm interested in the Bois programer. Can I ask from where please
Ill go to buy SVOD 4 to BIOS and SIO programming in a future... is expensive...
I need help with a Toshiba L850 laptop that No display. The power LED comes on soon as the charger is plugged in. It does show battery charge LED also with battery inserted. Power LED turns off if power switch is held On. No display, no external 5 v on USB ports. Have tried RAM cards and CMOS battery. Any ideas please, could this be also a corrupt BIOS issue?
Why didn't you get the bios file from dell website?
Recover memorey how to do that ?
Battery is draining fast what to do ?
i have a lenovo laptop, when i plug in charger it delays to detect charger and then after 20mins it starts charging what can be the problem??
Is that laptop based of 10'th (Comet Lake) gen of intel "i" CPU ? I wonder why it uses the old power cord plugin - the "wide" one ?
Precisions are well made and if the BIOS/UEFI corruption is the common issue I recomend everyone to buy them. Its prettty easy to fix in contrast with faulty CPU for example. Beyond that they offer comonents not avaiable at other laptop familes like outstanding display panels, detachable graphics cards, good keyboards and pretty much more security implementations.
I too see BIOS corruption very often these days...all manufacturers. Another frequent failure is, that the BIOS freezes somehow. You have to disconnect the cmos batterie, and its working again....
"the customer is always right" 🙂
Bad batteries cause the starting problems, still it’s easy to start them. Hotkey combinations start it up, for each it is unique. Most common is F2 + pwr on.
hello, Kindle recomend a good repair tool kit... I am going to learn repair.
When you suspect a bios issue, how do you know when to skip resetting bios (cutting off power to it) and go straight to rewriting the chip?
You don't skip it. You try to reset the BIOS and if that doesn't work and you suspect a corrupt BIOS, that when you try re-programming the BIOS.
I love your screwdriver. What is the make/model? Give us an affiliate code and I will be happy to use it.
Lets go special laptop for repair! :)
best technician.....
Sorin one question, cant you use official bios from dell in this scenario?
Ne. Razlikuje se ovaj u cipu i sa ofc sajta u tome sto je u cipu vec i deo koda koji je zaduzen za boot, pa bi samoim tim taj sa ofc sajta ubacen u cip bio neupotrebljiv. Zato se trazi kompletan sadrzaj cipa, tzv dump
no, official bios is an exe file that runs under windows only. If laptop doesn't start , you can't update.
@@orange11squares didn't know that, so everything is made for profit now
hi sorin . i want bios file for dell precision 5530 i9-8th . 25q80dvig 8m. do you have ?
Sorin Uneori problema cu bios-ul nu este vina producatorului asa ca mi s-a intamplat sa am actualizat bios-ul care nu era potrivit pentru modelul Dell corect.
Can somebody explain to me why the bios can not be reprogrammed while soldered to the motherboard? I heard somewhere that those usb programmers don't supply enough current on the 3.3V/1.8V line if that's the case couldn't one just jerry rig an external current supply to the programmers pin and save oneself the trouble of constantly having to de and re solder bios chips?
I did on my Asus K56CB laptop. Motherboard marked as K56CM rev. 2.0 . I used a "normal" CH341A programmer - bought fm AlliExpress 6USD ... , with that "clip" as Sorin. Only that I flashed a "wrong" BIOS ( I just searched/downloaded whatever .bin files I could find freely, not like Sorin - with "pro" / payable Discord assistance) Now I "have" an Asus S550CM laptop, according to "my' BIOS 😀- NOT working my dedicated Nvidia GT740M / 2Gb VRAM video card and Numeral pad on the keyboard ( those separate keys with numbers ) . Think I was lucky though , at least I am having something back from dead. Wrote this comment using this laptop.
@@celdepescaun39You can reprogram the Bios without desoldering the cip?
And if I have the latest bios, what can I do?
I can flash the original bios?
@@celdepescaun39 lol that's quite an awesome story. Surprised it works at all with the wrong bios. No idea where you got that bin file from but you could try the badcaps forum I found the bios for my old laptop there and the bin file was good.
yea they are prety sweet i have a precision 5570 that dent in the heatsink does not look great at all those precision should have auto bios recovery from usb stick btw does not mather what kind of servicetag is in there as long as one is in the bios even if you fill in a completly wrong one stll wil work fine the original servicetag is on the bottom of the laptop
There is no hardware or software guys anymore.. they combined all my friend...
I have a dell precision 7560, but it's not have discrete graphic card, how do i upgrade one for my laptop?
You can't.
👍
I think Windows is to blame for this one as they started pushing BIOS updates at some point which is insane, and most people dont wait for windows updates and just shutdown the machine
Even shutdown would wait for a updates to be over, must be force shutdown in the scenario you describe.
@@DarkGT I meant pressing power button until laptop turns off, so yeah, forced shutdown.
In theory, these updates should be reliable and failsafe, but I guess they are not.
@@Alex-mj7km Once Windows update destroyed my file system. I'm surprised from anything.
on newer version of windows 10 22h2 the firmware update is hidden on optional update and dont know if they include it on the main windows updates, or it has soemthing to do wil crucial fixes on bios on some brand like mabye dell or hp that forces it to firmware update?
Microsoft update to apply a BIOS update? No way... maybe the "intrusive" dell.. asus..lenovo tools installed from factory con do this.... but nothing that can't be fixed by a fresh Windows installation with downloaded drivers from official site... usually the first thing I do to be sure to not have crapware ... :)
DELL high class laptops are very premium and fast but very complicated
programmator with such device is able to operate bios chip at board, isn't it?
why bios chip was get off from plate for reprogramming?
You can't reliably program the chip while it's in circuit.
@@markanderson2904 thx for answer, but in this way, i can't even to image for what that device's clip exists
How to identify bios chip on laptop motherboard
Look for a chip in a SOP-8 or SOIC-8 package (they are most commonly used). See if it is powered by the coin battery (if there is one). Look at the brand name (Winbond is very common). Look at the part number on the chip. It will usually begin with "25" and have the size as part of the number, e.g., 16 or 32. The BIOS binary file that you are going to use should be the same size as the chip. If it's not, then that is probably not the BIOS chip. Although, some BIOS software is spread across two chips. Also, check out Adamant IT on TH-cam (search "adamant it bios") for man examples of BIOS re-programming.
Bro, my laptop is AMD, it has Radeon Vega 8 1gb graphics, I want to update the graphics, then do I have to buy a separate laptop graphics card, can I update only the graphics card?
අයියේ මගේ Laptop එක AMD එකක් ඒකේ තියෙන්නේ Radeon Vega 8 1gb graphics මට graphics Update කරන්නඕනේ එතකොට මට වෙනම Laptop graphics card ගන්න තියනවද , මට graphics card එක විතරක් Update කරන්න පුලුවන්ද
It depends. The graphics "card" in a laptop is usually not an actual circuit board, but rather the circuitry of the card placed right on the motherboard. That is not upgradable. If, like this Dell laptop, the graphics is on a separate board, then it might be upgradable if the manufacturer offers one (and drivers for it).
Well. Corrupted bios isnt Dell only issue. I had bios issues even with Gigabyte DUAL BIOS motherboards.

SVOD 4 programmer can modify bios
Try another time to save a bios.bin from chip, erase IC and restore same .bin file. Mani time for me working.
You could have programmed the bios without disassembling the laptop. And the "cooking is only needed when the bios file is encrypted.
how? do you need to use dell usb bios update? or use a cable of those reprogrammer tools?
Pleas what is the programer name?

@@ohmware2020 What is batter one RT809f or this ?
CH341A,, better is SVOD or RT809H
I think sorin mentiont that he needs to buy a faster one tho, so probably do some research on what to get instead of this one
dell used to be failsafe laptops shame

That's either here or there.😄

Sana all basic repair Ang tanggap 😅
basic?
great video and perfect explanation, i just subscribe to your channel
dude can you pass me a bin from a 7560 dell precision I try to extract from dell exe but don't have success
The bios was taken over to the point that it is admin protected on every thid how do i get around that? please do not tell me to do down load it will not alow me to press the enter key to install any thing!
You may have to read the BIOS chip, then find where the password is located in that file and delete the password, or do some other editing of the file to remove the need for a password. Then, write the file back to the chip.

This is sounding like programmed obsolescence.
No. Obsolescence is when something is no longer useful or needed.
@@markanderson2904 Programmed or planned obsolescence is the shutting down of an older product for a newer product or technology.
Obsolescence is as you stated. It is something that is no longer needed, or is obsolete.
