haven't used my RGB30 in ages & they're notorious for battery problems so I opened it to check for swellage & it LOOKS fine but I still don't really trust it... hmm...
I wish there was a place you could go to that was just like a fireproof room with power points where you could try charging dubious batteries and make sure they don't explode
Update I DID find the card it had landed on the sofa and gone down the crack of it But the console won't boot with it inserted so I guess it's possibly gone bad lol
