by titomno2Hi guys,
On motherboard ACER AN515-52 type LAF951P.
I fixed issue with not starting computer (it was the PQ201 component not working properly).
But after checking everything I have still an issue with secondary SATA connector JHD1 (for HDD typically).
Basically some HDD spin but are not detected by the bios.
Already tried following:
checked the 4 data lines
#2 RDSATA_PTX_C_DRX_P4 => CO18 (10nF seems OK) => RO24 (0Ohm measured at 0.25Ohms).
#3 RDSATA_PTX_C_DRX_N4 => CO17 (9.68nF seems OK) => RO23 (0Ohm measured...07-28-2024, 08:30 AM -
by MMH3Hello,
i have many 5050sff. all of them, and how i experienced over many years for all about 250 DELLs goin through my hands, are fully flashable and can be serviced in any way when the service_mode jumper is set.
Never ever i experienced problems with that.
Now i have one 5050sff machine, where this jumper isnt working at all.
I do not get the normal messge that the jumper is set when booting and a short test with FPT just confirms this. Everything is locked -->> EVEN for reading !?
The history of the machine is that i used it in my office... -

I have the above mentioned bord after repair, which was related to a lot of missing smd devices on the back of the board.
There were almost 20 devices missing, caps, resistors and some diodes/mosfets.
The board is generally working now, all PCIe ports are working, Windows installs normally.
However I have a problem with SATA ports 4-7 (the board has 8 SATA ports) - disks are not beeing recognized by the BIOS neither by Windows (which is usually normal in case BIOS does not recognize them).
The SATA 4-7 driver network is quite simple chipset<->buffers/drivers<->SATA... -
by hopkokHi masters, I need your help.
I am working on Lenovo Legion 16ITHg6
Motherboard number NM-D721, no BV, no schematic but I am attaching very closes ones.
INPORTANT: My motherboard version is with IT8258 IC, that is controlling keyboard and RGB LEDs.
My problem is on UI142, +3VALW_AG is not stable, floating from 0V to 3,3V.
AGKB_PWR_EN_N signal is floating too (that is why+3VALW_AG not stable).
Power LED is not working as well, power button working well.
UI26 ??? is there any firmware too? Powered by +3VALW_AG.

by ezeniaHi,
I have a LUMIMAN Smart Bulb that suddenly stopped lighting one day. The bulb is still detected in the app, but won't light. I've probed around and nothing seems to look off with any of the diodes, caps or resistors. The Bluetooth/Wi-Fi module seems to be working as it's still detected in the app. I even tried deleting and re-pairing the bulb (it didn't light, but I was still able to follow the pairing instructions), it re-paired fine, but still no light.
In diode mode, the LEDs all light up when probed so I'm guessing this means the LEDs themselves are OK. I was expecting... - Loading...
