Also known as:

  • Amptron PM-7400

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.

Notes:

"S" bios can only be upgraded with "S" bios, "L" bios can only be upgraded with "L" bios.

Difference with M519: has PS/2 mouse port and a Dallas RTC/clock combo instead of separate RTC/battery. Pictures are of the M519 because a good one of the M529 has not been found yet.
