RAM issue - error code 2000-0123 validation 49491

Hi SHAMANIAM,

The 0123 error refers to memory error.

There are 2 modules on your system. You would need to isolate if one of the memory modules is causing the issue or the slot on the motherboard.

One module is beneath the base plate and the other module is located beneath the motherboard.

Let us know if you have any other queries.

Unplug the system, remove or disconnect the battery and hold the power button for 30 sec.  Remove and reinstall both memory modules and then restart the system and re-run the diagnostics.  If you still see the same error, try one module at a time in each socket, re-testing until you isolate the bad module (if one module tests bad in each socket, replace it with a new one) or the bad socket (if both modules test bad in one socket, it's the socket that's bad -- in that case, the mainboard will need to be replaced).
