Resposta para "MacBook does not work on AC power"follow up: re Jethro: - is the DC-in board (only) a connector, or does it contain electronics ? - visual inspection of the battery connector shows no corrosion. re Ralph: - if the DC-in board is a connector only, I find it hard to believe this can malfunction. - if so, can a claim for repair be covered by an (extended) applecare warranty ?

Resposta para "Will not boot, grey screen"My G5 had the same problem. After 4 years and a couple of months with no problem at all it suddenly stopped working. Restarting the Mac failed with the grey screen as mentioned above. After doing the usual to check if it was a software or a hardware problem I found useful information in the links below. The problem may be caused by fractures in the solder joints between the powerpc processor and the logic board. This may be a design flaw in the otherwise great machines Apple produces. What is needed is a "reflow" of the logic board. Contact Jürgen Geisbauer of the German Firm "Golytronic" (www.golytronic.de) for a really brilliant suggestion (which is too good to give away here) to check that this is the case with your mac too.My Mac is now in Germany for a reflow. If this helps to bring my mac back to life I will of course keep you posted. check out these links: http://discussions.apple.com/thread.jspa... http://discussions.apple.com/thread.jspa... http://en.wikipedia.org/wiki/Reflow_sold...
