Usually there's a resistor you can remove or change near the cpu to disable the onboard memory and use only dimm but you'll need schematics and board view to find it if reflow doesn't work
A few days ago, I had an Acer laptop from a customer with faulty onboard RAM. They were getting like over 100 degrees, crazy! I tried reflowing and nothing worked. I took them off but keep in mind, the laptop will still not work because the bios will still search for the onboard RAM, because it's programmed that way. The solution is to mod the bios, and disable the onboard RAM. Then you can just plug in a normal RAM stick and you are good to go :D
Wow, I can't help but wonder what it was like to figure out a fault like this for the first time.😤 Nice to know what to look for based on experience, it could be a big time & aggravation saver. 👍 Great lesson!!
5:35 - Its obvious that marks started disappearing on left most chips. Meaning high temperature. Fluctuation in temperature is what makes solder cracks. 17:33 - There probably have been multiple problems. It changed its behavior after reflowing first 2 chips, so something was fixed/changed. After reflowing second group it started working, and was functional 100%. You didnt reflow only second group to be sure its last one. Simple method of deduction. Good method and demonstration but I think its better to reflow to be sure, sometimes can happen that pushing will not help but reflow will help. Sometimes you have to remove chip to see that solder ball is missing.
Sir I bought a rework station 1 year ago, still in its box, I have a 55" TV not working 2 years ago (display issues) I had some time and said... I'll watch some videos to know how to use it, yours was the second video and a light bulb turn on over my head! I open the TV, take out the main board, I reworked the 4 ram memories and the processor too, put thermal grease, assemble all back, and I'm watching my TV all excited! Thanks for sharing your knowledge!
The flex in that laptop is crazy! most probably the cause of the RAM error. That or someone vented on the keyboard and thumped it. Reflowing the RAM chips can also be a nightmare on Lenovos because of the brown glue they insist on using. I've seen a few newer HPs with the outer pins on the RAM sockets loose just due to pressure from typing. Modern laptops have poor structural integrity and break with little effort but people want thin tech and will have to pay the price in longevity.
🌄🧡💚crazy, agree!☺️ Tablets are thin but have not the keyboard whole with poor plastic on it. The screen is the best way to put beside the motherboard like tablets, I have an octocore, and very easy to go inside. Perhaps in future, that's an evolution to promote, making the Keyboard a separate thing, with one piece screen and motherboard, even on a 15" or a 19", and why not touch screen. I uses old laptops for music so I have All generations ones, because music hardware's are not updated since window seven sound system, and related to graphic cards, so I can see the evolution opening them, some were iron bunkers, but now for sure, they seems made like a smartphone mother board.🤗 Quick to destroy a solder layer access .
10-15 years ago the board was close to the bottom. with bending protection. Today it is close to the keyboard, all the typing on the keyboard is slowly destroying the motherboard. Fans are getting clogged more small ventilation holes
A little tip, if the chips are actually defective it is cheaper and safer to buy a RAM module remove the chips, reball and solder on the board rather than buying the chips themselves. I bought an 8gb ddr4 ram module for 15usd from aliexpress to fix the onboard memory of a laptop, If I had bought just the chips it would be several times more expensive and I could possibly end up with fake/faulty chips. Just make sure the chips on the module use the same package and preferably have the same specs as the ones on the board.
Hi Sorin. Followed some other electronic repair youtubers earlier but they started to speak about their customersin a quite unacceptable style so I left those superhuman channels. It seems, there are two proper guys left where this problem never occurs. You are one of the two. Please, keep your style, show your success and also your failures, keep acting like this. Great channel with great quality content we can learn from. Greetings from Hungary.
Your channel it's really good for learning repair eletronics. It's not like other channels that can only repair shorted components using a thermal camera. Your vids give a lot of different cases of faulty devices which it's very good for learning. I must say that I have learned a lot from yours vids and my skill to repair stuff has increased a lot. Thx for your vids and keep the good work.
update. Amazing that could be a sold issue. Happy to have brought an Air Solder !🙏🧡💚🤗 thanks to your videos !. I will try that on one dimm that were not working, causing blue screen and freeze on a working XP laptop. I just changed Battery unmounting all the motherboard, and I fixed the second issue just by taking out the second ram memory, I added just previously. I will see when having time, but an interesting subject for me, that's an issue I had lot of times having lot memory pieces, I generally change the not working one. Happened me few days ago, but not tried to repare the Ram part. Will update this comment if necessary! Thanks🙏💚👍
In the past I came arround a laptop where if fan was not connected laptop wont turn on... so maybe the left chip was the issue. I was cringing when you flexed main board so much but everything worked out on the end 😁. Good video, thx.
Great content and thank you for everything. I've learned so much from this channel that no school can teach me. Just one advice, don't open laptops on the corners. That puts all the force on one hinge and can weaken or even break the hinge(don't ask me how I know) :D
I am watching this from the exact same laptop. To be precise, mine carries the model no. Ideapad C340-14API (Ryzen 5 3500U, 1 TB SSD, 14 inch IPS with touch, 8 GB RAM-I have upgraded to 20 GB - 4 GB onboard and 16 GB module). My unit came with Samsung memory though (both the onboard and the expansion as well). 3.5 years so far and still going strong.
For me I will first detach the battery from the board before anything, I cannot still believe that seems like a magic to me, Sorin please I want to come to you, I needed to inherit all these knowledge from you..........
THANK YOU VERY MUCH FOR THE EXPLANATION OF THE MEMORY PROBLEM A QUESTION HOW COULD YOU BERIFY IT IF WHEN YOU PRESENT NOTHING AS SHOWN IN THE VIDEO THANK YOU VERY MUCH
18:12 - I’m impressed with the screwdriver you’re using. What’s the model you’re using? It sounds like it has torque capabilities. When I search for such, I find a deluge of choices.
Good error finding, in my experience reflow doesn't work, lead free pads get oxidized and the flux can't get to the bottom of the chip, only at the board, so solder won't stick to the chip. Reballing solves the problem all the time (if not the chip has ripped pads). Leaded balls and 90x90 stencil is the best, reballing 4 ram chips take 10 minutes and jobs won't come back dead.
Can you test again remove the 2nd fan? It could be the system detected no 2nd fan plug in and refuse to turn on, which also explain why it also refuse to work when you press your finger on the same chip as before.
LOVE this channel and everything he does, so much better than all the other channels BUT........ just have one worry on "cooling Pads" um. when you pull up a reflow temp profile for a chip, it gives the time to heat gradually UP to temp but makes it very clear to pull nozzle away SLOWLY to cool not shock the chip. So is fast cooling with a pad will cause fractures soon of the balls? instead of letting it just cool for 10 mins then test? Are the cooling pads undoing all of Sorens great work and will fail again instead of long tern repair?
Hey Sorin, I wanted to play along in diagnosing the fault but I already know what it is because I saw the title of the video. Is it possible to list only the symptoms in the title or do you need to put the cause of fault there also in order to get views?
The problem will probably reoccurr and this was a temporary fix due to the flexibility of the motherboard and the quality of the solder used on the ram chips.
Thanks Sorin, excellent lession! But in my opinion in real life it is not reliable. I would remove the soldered memory chips (install the memory module in the slot) and it might be necessary to configure the straps there or flash another BIOS.
I just discovered that memtest86+ has problems and I encountered some with my computer. I also discovered that my desktop will run with one stick of RAM instead of the recommend pair. I had 2x8GB installed and it only saw 8GB. I cleaned the contacts and reseated the RAM and the computer saw both chips. memtest86 also only saw 1 chip until the cleaning and reseating. Online research shows issues with memtest86 and multiple-core processors. 16GB was OK but I sometimes like to run several virtual box instances so need the memory. RAM for a desktop is cheap and I further upgraded to 32GB. Do a search for memtest86 freezes or hangs for more information.
That little chip on the ram could be the cause of most ram trouble. If the operating system is illegal copy, it causes memory trouble, too. Legal win clears this problem. Mine runs at 333 mhz 50% power plan, and runs very well at 1 ghz cpu speed. Second hand memory modules can be fixed when inserted into a legal machine. The speed increase won’t be immediate, only after a while.
The way i figured out the ram vdd was pressent . I usesd a themal camer and found 1 memory chip was not getting warm other chips we're gets warm. I removed the module and reballed and solder back.. problem was solved like this for me
Hi Sorin, thanks for the video. At 9:04 you're saying, it is going to work if you take out the RAM chips, but I believe it will not work, I already tested. You have to disable the onboard RAM memory hardwarely or softwarely by editing the BIOS. Here is video of testing and how to disable it by editing the BIOS on a Lenovo laptop: ua-cam.com/video/WQfseAf-a1I/v-deo.html And, I think, we will need this more often in future because, as you say, all new laptops have onboard RAM integrated and it can fail. Cheers
I have a strange situation. My Dell Latitude 7390 2-in-1 will boot to Windows 11 on external SSD, but I get BSOD when trying to boot to Windows 11 on internal SSD. I ran MemTest86 and the test aborted almost immediately due to too many errors. Why would it boot and run just fine using external SSD with so many RAM issues?
Technically , it should work if you get the same ram type with thr same pinout but larger size. We do it on microcontrollers by swapping out the spi rams or spi flash memory for larger ones. But you can only do that if the laptop already has another variant that has the larger chip. If not its unlikely thr larger size to be detected or even made use of in the laptop. A similar thing I saw was upgrading memory on iphones where the emmc is replaced with a larger one. If that worked , then the ram definitely should imo. But those phones did have the larger memory versions by retail too.
Nice work, I don’t understand why the manufacturer goes with this approach? If your memory rams goes bad you can’t replace it unless you have a professional technician to diagnose the fault. :/
what are the odds 😮, I'm working on a lenovo ideapad 3 and it's seems to be working fine however it's secretly suffering from on board ram issues, this led to it's hhd to die, replaced it with nvme ssd and still the ram corrupts the files when trying to install windows, but it works when the drive is installed on another laptop then plugged into the lenovo
If you'll excuse me, I've got the shape of a hp 650 g2 with a rehearsal that could be opened up to a copy, and it's possible that before I do, the Rustart, knowing that I'm shipping Beus, and the same problem is that your presence is able to save me.
I ripped off three capacitors on top of my memory while inserting my laptop memory as a flat-blade driver...Can't I use it? Does it break down while using it?
Friends, if you do it, practice is meaningful, and theory is only the foundation. To become a master, you have accumulated experience from the maintenance of countless laptops.
Hello Sorin, as always a great professional, and with incredible knowledge in electronics, and also your proven effectiveness in all the repairs that you teach us. Too bad you're not around (I live in Spain - Granada) to have a coffee with you and say hello
i have always been a big fan of yours but the main power rail is what i don’t know i really can’t see that capacitors and i wish to know it i really want to sire
Have the same issue but in ram slot It was working fine for a year Then sometimes it works and sometimes not Then it starts showing same screen (when u pushed the 1st chip) when im working on it And now it doesn't even work Any solution!? I have one ram slot just like the pc in video
If you want to measure the voltage drop with a multimeter, you can follow the following steps: 1. Select the appropriate range: Select the appropriate range on the multimeter according to the expected voltage drop. Generally speaking, a larger range can be selected at the beginning, and then gradually adjusted to a more appropriate range according to the actual measured value to obtain a more accurate reading.
Usually there's a resistor you can remove or change near the cpu to disable the onboard memory and use only dimm but you'll need schematics and board view to find it if reflow doesn't work

which type of Reballing flux have you used

Once upon a time, computers beeped codes that immediately told what’s what.
very nice,how long laptop gonna work after reflow?
Sorin as usual good fix , I suppose the moral of the story is just reflow all chips . thanks for your time Jim
or, reflow till work :D
The problem will probably reoccurr and this was a temporary fix due to the flexibility of the motherboard and the quality of the solder used on the ram chips.
What heat gun and flux (rosin) do you recommend?
Yep, getting some of these on board ram issues with Lenovo notebooks recently
Do you think it didn't boot because the fan was not connected? Thanks for sharing!
Hello sir, Can you tell me which flux (for reflow) are you using..?? This video

Hi Sorin, thanks for the video.
At 9:04 you're saying, it is going to work if you take out the RAM chips, but I believe it will not work, I already tested. You have to disable the onboard RAM memory hardwarely or softwarely by editing the BIOS. Here is video of testing and how to disable it by editing the BIOS on a Lenovo laptop: ua-cam.com/video/WQfseAf-a1I/v-deo.html

I have one ram slot just like the pc in video
it's great job !!!!
Will it work with 1 ram put in to slot without reparing soldered ram
No.
sir please guide us if caps lock button work what does it mean internally , hw to identify which ram chip has been failed ,
Sir, How can we check a faulty Ram Slot and Faulty Ram with Multimeter? I mean by checking Voltage drops and so on,
It can be anything in that general area as you are bending the board.
If you want to measure the voltage drop with a multimeter, you can follow the following steps:
1. Select the appropriate range: Select the appropriate range on the multimeter according to the expected voltage drop. Generally speaking, a larger range can be selected at the beginning, and then gradually adjusted to a more appropriate range according to the actual measured value to obtain a more accurate reading.
