回答“Can I replace/upgrade 4850 graphic card in 2009 iMac”This is an old question, but I thought I would add. I was able to do exactly what you asked in my late-2009 27” iMac. I found a Radeon HD 6770M 512MB GPU that was pulled from a 2011 model on eBay. It dropped right in and since it came from an iMac it woked just fine. The only big issue is that I am running El Capitan and I was not able to upgrade the OS (I forget if it was Sierra or High SIerra). It would error. There seems to be a conflict with the installer and the graphics drivers. I’m sure it has to do with the non-standard card that is in the machine now. I am happy to just run El Cap until the machine dies on me, but keep this in mind.
回答“Time display unreadable as it is missing several characters”I have this same problem with the iBT97. Once a year or so ago, this came up and the unplugging everything solution worked. This time it is not working. I unplugged it and took the battery out and left it that way for a whole day. When I plugged it back in, the display is almost unreadable. Anyone figured out a more involved fix? Replace the display or a board?
