"How to teardown the shutter button"に関する回答Thanks for this! I have trouble with the rotary selector at the back of my E-PL5 but I have been too afraid to peek into any photographic camera since my teens in mid-eighties when I sneezed and lost two miniature parts of my mother's '50s Agfa camera (though I doubt I could ever reassemble that camera with all that super miniature gears, springs, levers and stuff even if had not sneezed away those tiny parts :-)
"Ipad Dock connector no longer working"に関する回答Ashley's simple solution works! ===== I guess that the complex metal sandwich of the connector assembly can become permanently distorted or misaligned under proper direction force and this means the pins are not making good contact any more so by adding slack to the socket housing the cable plug aligns it properly upon insertion ===== My opinion is that this is another (understandable in the long term) design shortcoming by Apple but I guess that many people must have paid good $$ out of warranty for such repairs because Apple is not as perfect as it wants as to believe (and pay) or admit themselves. ===== Anybody knows what an Apple Genius does on this occasion? Says "pay $$ for repair" or "wait 10 mins for the tech guy to fix it"? I guess the "proper" solution is a not cheap whole integrated ribbon/socket replacement.
"Is there no CMOS RAM battery on this model?"に関する回答Indeed there seems to be a tiny battery on the logic board as Gabe says above. Update: Ok, went ahead and desoldered this tiny "battery" from the Macbook Aluminum 5,1 logic board (it can be seen here) as it was not obvious what the heck it really is as it has metal soldering tabs attached to its body and I had to remove them to see its enscripted part number data. Before the "operation" I measured 2.8V on it and it is too low for the usual and similarly looking lithium button battery so I had to check it on my quest to solve my random unexpected shutdown problems. So..... [Drum Roll] it is this one: XH414HG and you can see in the SII data sheet that it is not a battery but a 80 000microFarad / 3.3 Volts capacitor. SO, DEFINETELY NO PRAM BATTERY - it is a SUPER CAPACITOR in the Macbook 5,1 model for sure! BEWARE: With the capacitor detached the macbook does not power up with the AC adaptor only - it needs to have its removable main battery inserted! (I believe that is the reason they removed this PRAM...
