New to this forum, I've been looking for an APC LS700 schematic for awhile (to replace a burnt resistor). Just hate it when I need to thrash something that is repairable.
Hopefully I'll also be able to help other members as well in the future.
Hi, I just stumbled onto this forum looking for information related to amateur radio equipment. Fascinating little discussion environment!
My name is Chris, I am a mechanical engineer and I hope I don't ask too many stupid questions here. Thank you for allowing me to be part of your community.
Hey all, joined this form bc I'm a rookie at electronics repair and recently my Asus GL503VS laptop crapped out on me mid -game and now won't charge... Hoping to diagnose problem myself vs paying someone $400 to screw up my machine worse than it already is .. If anybody is gonna completely nuke it.... It's gonna be me 😂
Gday, Just a repair guy constantly trying to find ways to diagnose, repair, and improve the multitude of hardware rubbish out there. My main focus of this forum is information around - laptop and desktop m/b's - pc and mac. and power supply repair. Have done a few successful surface mount repairs but have a long long way to go !!.....thanks in advance.
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
