My name is Nicolás, I'm from Argentina. I'm a student currently working in electronics repair, mainly focusing on laptops and console maintenance. I'm really looking forward to learning from this community and contributing whenever I can.
Ahoi. I've decided to put my small home electronics lab to good use and fix an older computer for retro computing (mainly for hobby and self improvement purposes). Will see how it goes. I'm happy that classic forums still exist with an enthusiastic community. Nice to meet you all.
Hi, is there any way to dump and write the eeproms without a chip programmer? Everybody has here a device like T48, CH341A etc. ? If yes which is the cheapest one it works for most of the chips on dell, hp etc.?
Hey everyone! Chip Darnell here. I'm an applications engineer with a background in DSP, embedded systems and small signal audio design. I also hold an Advanced Extra Class HAM Radio license, (my call sign is KZ4QS). I play guitar and bass and love designing gadgets for my small home studio. Keep rockin' everyone!
Hello everyone,
I'm a hardware enthusiast from Bulgaria. I love working on component-level laptop repairs and diagnostics. I've been using a ezp2023+ programmer lately to solve BIOS and ME region issues.
I joined this great community to learn from the experts here, troubleshoot some tricky boards, and share my own experiences whenever possible.
My name is SIKORAK666. I'm 36 years old, and I'd describe myself as an "electronics gambler" – a hobbyist who just can't sit still without a soldering iron in hand. My main passion is music – I play, and for the past few years, I've been building guitar effects pedals and tube amplifiers. I love that analog grit, but I also enjoy dabbling in digital circuits from time to time.
Beyond audio, my second love is old-school gaming. I repair NES and Pegasus consoles – from simple switches and broken traces to replacing dead PPU chips. There's something magical about bringing those old boards back to life after a good cleanup.
And to keep things balanced, I also enjoy tinkering with modern tech – in my spare time, I work on various projects using STM32, Arduino, and for simpler tasks, Raspberry Pi Zero. I'm still not sure who's smarter – me or the MCU – but I'm working on it 😄
Hi all, just joined this forum to learn more about electronics repair. Have a long dead GPU here which will serve as my first "advanced" victim and hoping to find some resources here.
Hi Everyone, I am joining today to seek some help with a BIOS lock on my Acer laptop. Beyond that, I am looking to get back into tinkering with electronics as a hobby, working with circuit boards and doing some repairs. Glad to have found 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
