My PC motherboard have few dead caps (few years already). Its working good (pc not starting right away tho when switched on, but after 5 mins or so system starting) with warm room temperature, but when temp. falling to 23 C or lower then writing errors appears on harddrive. Temperature >23 C - no writing errors. How this phenomena can be explained on physical level? Dead caps still have some capacity and working better when its warmer? Or some other explanation?

Re: Interesting phenomena
lower ESR when the caps heat up..
interesting fact is that this wikipedia article points to "Capacitor Plague".. and that badcaps doesn't appear in the linklist of that plague article..
i've expected a link to badcaps.net there..

Hi,
I'm new to MATS and can only use it after watching a Youtube video, downloading the one he linked to (version 400.184) and running it without changing anything. I have no great understanding of it.

Mine - Nvidia GTX 1080 not used for 3D games, just basic stuff.
Inno3D RTX 2080 I bought faulty hoping to repair for my son's PC.

This sums up discussion related to Lenovo P14s Gen5 in this thread. Credits go to Sbaro and especially Maxpower3. The locked dump is attached.
The device is based on NM-F871 motherboard with Nuvoton NPCK397 series controller. The motherboard also contains three BIOS chips: two different Winbond chips for main BIOS and external EC flash, and also a Gigadevice chip which purpose I do not know. The password information is contained directly in controller and thus can be manipulated by reprogramming it, so reprogramming BIOS chips is technically not required, however you may wish to make...
