Congratulations! It is a wondrous thing when the POST startup chime fills the air, the screen flickers to life, and all is well. | |

| Jun 27, 2022 at 5:22 | comment | added | peterf | thanks for the tip re the battery. just replaced that, same result. But, for whatever reason, one time while connecting the power cord (and the new battery in place). the white front LED now started blinking permanently... but no other time after that... HDD and everything else has been removed, PSU still makes the same two clicks... I guess I'll order a replacement power supply and see if that fixes it... | |
