Known issues:

  • DALLAS RTC coin cell empty

The motherboard's Real-Time Clock (RTC) chip contains a coin cell that may have drained, causing the loss of CMOS settings. This can result in an inability to save settings, causing system instability or failure to boot. To fix this, the RTC chip can be replaced with an equivalent or repaired by cutting into it and soldering on a new external coin cell holder. Replacement guides are available at https://github.com/necroware/nwX287 or https://github.com/necroware/nw12887, depending on the actual chip used.

  • Faulty or Leaking Electrolytic Capacitors

Some motherboards may contain faulty or leaking electrolytic capacitors, which can negatively impact system performance or stability. These capacitors may exhibit issues such as bulging, leaking, or even exploding, potentially damaging other components on the motherboard. Users should inspect their capacitors regularly and replace any that are faulty or leaking to avoid damage or system instability.
