Disable on-board memory at HW level on ANY laptop
HTML-код
- Опубликовано: 10 июл 2024
- Learn to disable the on-board memory of any laptop and enable the SO-DIMM slots. Learn to read and understand the schematic and locate the components on the board view.
In this example we will fix a Lenovo ideapad 3 14ADA05 that has a problem with one of the chips.
The easiest way to fix this rather than reball or replace the memory chips, is to disable the on-board ram and enable the so-dimm socket.
Fix laptop not starting problem, black screen issues.
Thanks teacher
Video dis to uma laptop
Please help
No. If you just disorder the cips, you will still have problems, the computer will still think it has the on-board ram. You have to tell the computer there is no on-board ram by changing the configuration. You do that by moving the resistors. You don't need to bother to remove the faulty ram.
Hi do you have a schematic for NM-C861 same that lenovo you have repair it different design . i have also need to disable my laptop ram onboard but icannot find board view and schematic pls help me sir thank you
check out badcaps.net if its not there, just ask in the forum, some one will help
does desoldering the all onboard ram chips would work and the dimm slot if populated should be the one prioritized?

@@salvamipc thanks alot for the explanation it helps a lot by the way if you can make a tutorial too of disabling dedicated gpu in laptop if its faulty and only will use the integrated igpu of intel cpu thanks alot!
Reflow is a 2 minutes job, how can this be more expensive than driving into schematics and boardview ending on a soldering job anyway??? 🤔
reflow is not a fix, not a professional one anyway. Is one thing you do it for you, other you charge someone for fixing the laptop just so they come back with the same fault. Besite, Lenovo puts underfill on the corners that gets under the chips, so when you heat up, because the chip don't move freely, the chances are the solderballs will just come out.
Reflow we only use it just to confirm the fault. Reball yes, but removing all 4 chips, cleaning the board, cleaning the chip, removing the underfill, reball the chip and resolder will cost more. But hey everybody is free to do the jobs as they please. We prefer to make sure the laptop has been properly fix when we return it to the customer, rather than just heating the chips and call it the day.
Beside the purpose of the video like I said is to explain how to locate the resistors and make people understand the schematic, so they know what resistors, why and where they needs to be moved. I never said this is the only way, I think I did said in the beginning of the video you can reflow (which is a no for us) or reball the chips. But I thought if I was to make a video, would be more interesting showing the proper way, so that people can actually learn something, rather than just heating up the chips.
