That's one thing that makes it unnervey. I'll put my hand around to the |
24 |
back and feel those little bumps. I wait until I think it is done but |
25 |
just as I'm about to power it off, it bumps again. It's so |
26 |
unpredictable, I never know if it is done doing its thing or not. Just |
27 |
like now, it's unmounted, did that during last reply, it hasn't did the |
28 |
bump thingy while reading your reply or me typing mine in so far. Now |
29 |
as soon as I reach around to turn it off, it'll likely do the bump thing |
30 |
again. lol |

One thing is for sure tho, if you unplug the cable, whatever it is |
33 |
doing, it's internal. Sort of hard for the puter to be doing something |
34 |
when it isn't connected. That narrows the options down a lot. That's a |
35 |
good piece of info there. |
