I’m an electrical engineer (microelectronics) but have been working mostly in embedded systems engineering roles. I’m passionate about electronics, especially vintage and I like to push the envelope. I’m a big Mac nut (have been pretty much my whole life since way before Apple was big) and like restoring old hardware.
This seems like a great place to find information related to my hobby (I can’t believe I haven’t been here before!) and I’m looking forward to contributing my share.
Hi everyone, I'm another victim of the dreaded HP 250 G6 bios update. I've searched with Google and it seems that they have screwed A LOT of people with their defective and horrible bios upgrades. I'm hoping I could find some miracle to revive my laptop!
Hi, my name is Pedro. I'm 38 years old and I currently work in a warehouse in the quality control department.
In my free time, I really enjoy tinkering with computers and programming. I'm always curious about how things work and love diving into tech projects just for fun or to learn something new.
I strongly believe that knowledge is power, so I'm always looking for opportunities to learn and grow—whether it's a new coding language, a tech trend, or something completely different. I'm passionate about improving myself and staying mentally active through continuous learning.
I am casper from Holland. I have been repairing laptops and pc's since i was 10 years old. Now i want to make the next step in trying to do motherboard repairs. Hoping to Learn and gather New information from this site.
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
