Re: New Members - please post your introductions here
Hello. o/
I am new to forums in general except for reddit.
I don't really know how they work or proper educate.
I am a small type technician that has recently starting fixing mortherboards.
I have soldered in the past with HDMI ports on game consoles, charging ports on iPads and DC jacks on laptops.
I just recently discovered my first real repair on a MSI gaming laptop, identified a shorted mosfet and I'm trying to expand.
I don't know how to create a post and I am looking for someone who can help me with my newest problem. I have a motherboard I would like to request some help on. How do I format the request properly?

Hello,
I'm a professional electronics repair tech that focuses on pro audio gear in my "free" time and industrial building automation systems for my day job.
I'm in Louisville, Kentucky.
I've joined a few forums over the years, but I've yet to find one that was truly great. I came across a thread on this site that blew me away with how knowledgable everyone - including the OP - was. I'm looking forward to being involved.

Howdy,
As the handle indicates, I've been at this game a while. As in my first project's breadboard used real wood, screws, and Fahnestock clips. Back in the day when debugging a circuit meant poking your galena crystal in a different spot. Vacuum tubes? What, were you born with a rich daddy?
My first computer was built by wire-wrapping the RCA 1802 CPU to a few other ICs. I programmed it in machine code with toggle switches. Back then it was understood that "core memory" was a reference to a maze of wires and tiny ferrite rings acting like transformer cores. I couldn't afford a surplus minicomputer memory board however so I had to make do with one of those newfangled CMOS memory chips and a battery. As my hands kept cramping up I developed my first real program for the 1802: a custom monitor (the ancient ancestor of today's BIOS programs). Getting a hand-wired circuit to accept hexpad input and drive a surplus calculator LED display, now that was programming! Putting my code into a 1702 EEPROM made me feel like I was ready for a job at RCA.
So yeah, pretty old.
My computer expertise has (somewhat) progressed with the times, but I haven't worked professionally in electronics since the 80s so there may be gaps in my knowledge. Hopefully this forum will teach me a few things. I've noticed over the years that diagnosing a problem is harder when you can't count on flames and smoke to provide a clue.

Hello,
I'm 27year old from Latvia. I have been repairing various electrical thing for at least decade.
Also have made things with small microcontrollers as Arduino, but never have advanced to these 32bit systems
please help friends thinkpad T470 board CT470 series NM-A931 error post "bottom cover tamper detection error"
I've already
flashed the bios clean me and updated from the Lenovo site, then removed the switch and immediately jumped the S3 from pins 1 to 4, 2 to 3 but the problem remained the same, thank you
please help friends, I have 3 T490 units with the same case, the USB type C is completely dead, showing 20v 0 amp, loss of voltage VINT20_IN resistance to ground is fine, thank you
I think the problem is that I lost the voltage at PQ0008 pon 1 -PWRSHUTDOWN which should have been high which was picked up by R9512 VCC3SW, thank you very much for your help
Please help friends, thinkpad t480 nm-b501 is dead, help me fix it, thank you
usb meter 20v 0.00 amp, after I took the VSYS measurement the drop was only `9.2v which should have been 10.2v I measured from a normal matherboard machine, the VSYS path resistance to ground diode mode is 1900 thank you
