Re: Cyberpower CP900EPFCLCD - F03 Error
Well, if you can find a schematic for the UPS, that would be great. But if not, the VIPer22a datasheet does contain a lot of useful information.

Re: Generic Magsafe charger ghost touches

Re: best cheap/free scores 1.1
Thanks for the reply / confirmation. :)
Yeah, I figured they were a good deal, even just for the DVD drives and PSU in them (if nothing else). I just didn't want to be hoarding in on stuff that...

Re: The ghetto mod thread

Re: Post your worthless and/or pointless repairs
Well, I meant as a brand name. ;)
Otherwise, you can see how one of these has popped from its bottom. I'm sure it must have made at least a "muffled" pop inside the case. Definitely NOT boring! :D...

Maybe do a "side fan" cooling mod (https://www.badcaps.net/forum/attachment.php?attachmentid=182617&d=1536912433) ;) - that way you won't be blocking (and even providing cooling to) cards in...
