by acedogblastThis is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
by chth96I want to purchase any good flux remover But "chemistronic flux off es835b" is the most common flux remover in my nation..
Is it good to use chemistronic flux off es835b for flux remover?
Or I have to purchase "3m novec flux remover" which is quite expensive in my nation? -
by Isabella91I have seen many posts where the eMMC can be read via a SD card reader, however can the opposite be achieved?
Read/Write a Micro SD Card from an eMMC Socket.
I have a Motherboard with a Kingston BGA153 ball socket, using HS400 bus mode, which is 8bit, as Micro SD is usually 1bit or 4bit mode, I accept that a loss of speed in read/write will occur, but I would sill like to convert.
Theoretically speaking, Im thinking if I hard solder DAT0-3 from eMMC to SD Card Reader, this should force 4-bit mode, or only DAT0 to force 1-bit mode.

by warsztatHello, Acer AN515-57-577G JDIMM1 socket does not work. GH51G LA-L181P, 2x DDR4 RAM, both good, both work well in JDIMM2, neither works in JDIMM1. The laptop displays BIOS, when the JDIMM2 socket is occupied, you can run Linux on USB, then everything seems to work ok, there is internet access and you can browse the contents of the 512 GB SSD in Windows, but starting Windows ends with an eternal spinning circle, maybe there are corrupted files. When the RAM is inserted into the JDIMM1 socket, the laptop starts but there is no image and the downloaded current does not change and the output is ~2.25A....

by tony359Hello all,
I am experimenting a bit with reflowing larger components - ideally I'd like to reflow a PS4 APU or a GPU for example.
I know it's impossible to reflow such large components with just hot air so I bought a pre-heating plate, T-8280 classic Chinese machine, which seems to be working fine besides it's a little slow, which shouldn't be a big deal.
Now, my hot air station is a Aoyue 852A++ and I feel it's a bit weak when used with larger nozzle. I tried reflowing a laptop chipset using one of those large, rectangular, nozzles and I failed miserably,... - Loading...
