For the second time this week I received a Lenovo laptop with onboard ram and one sodimm slot. Both laptops run stable from their onboard 4GB RAM, but turn out to be very unstable when there's a sodimm inserted in the slot.
Both times it was a GS44D/GS54D NM-C711 rev 1.0 board.
Both times there were no loose pins on the slot and it did not matter what sodimm I put in. It just artefacts and crashes randomly when there's extra ram.
What I did notice is that almost all coils have very dirty phases one the mosfet side when checked with an oscilloscope. Not something I see very often....

by Joyoungjaehello everyone
i have a problem to a1706
First of all, it was delivered because the power was not turned on.
5v was confirmed on the voltage meter.
The battery was removed and checked.
A short was confirmed in the ppvin_g3h_p3v3g3h line.
During the tracking process, u7000 and d6902 were replaced and u6903 was reballed.
The cause was c7081, and when I removed it, the short went away.
However, 5v still came out from the voltage switch, and I confirmed that a short was coming out of the l6900....Today, 09:06 AM -

I disassembled the laptop and I saw that L5100 is burned, I removed it and I connected that rail and it seems to be working. It's a problem if I leave it like this? Or I need to install a new inductor?Today, 09:04 AM -

by CrystaleyesHi all.
Recently I picked up a vintage HP 37717B communications analyzer which uses one of these MML200 Coutant power supplies. Needless to say the PSU is not working, and surprisingly there is apparently nothing available on the web regarding repairing one of these. No stories, no schematics, zilch!
There[I] are [/I]however many companies offering repair 'services', however I don't have the luxury of sending it off, so am intending to do the repair myself.
I admit right now that I am no expert on smps repair, although I do have a grasp on the principle of the general...5 Photos05-29-2024, 08:23 PM -

by s_henyaHi guys,
Just found this old but nice IMac 2012.
current user had a password which i dont know.
i want to format it and do a clean IOS installation.
i tried command. + R after powering on but it didn’t do anything and IOS continued to load.
i tried the online recovery but it gave me denied icon after connecting to the Wifi.
is there any working method to format it?
guess i can take the long way of ordering the prying tools and format the hdd using another pc.
but i was hoping for another quicker solution....Today, 06:37 AM -

by martin86Hi,
i had a HP 640 G8 with a DA0X8AMB8E0 Board. I would Flash the BIOS, but i used a CH341A Programmer with 5V instead auf 3,3. Then I thought the BIOS was now defective. I have already replaced it with a new one (flashed the same BIOS).
With the new chip, the notebook has the same error. The charging port lights up once and then goes out again. The notebook does nothing more.
I iced the board with a cooling spray to possibly find a chip that gets hot or has a short circuit. Unfortunately, I didn't find any. I suspect a fuse might have blown. Does anyone...Today, 02:47 AM
