Marin Mac Tech used to offer efficient reliable service, but the last few times I've used his service, he has seemed much more interested in padding his bill and selling me unnecessary expensive gear. This most recent experience was the worst. Took in my NAS, ran up a large bill running diagnostic tests, told me it was the power supply, I ordered a new power supply, tells me it's still broken and now I should buy a very expensive one from him. Ridiculous. Not sure what happened to cause this slide.

MacBook Air components are officially non-user-replaceable, though third-parties do sell upgrade kits for the SSDs. The flash memory and battery are enclosed within the casing, with RAM soldered onto the motherboard. The flash memory, difficult to access, has a 128 MB cache and a mSATA connection (updated to a proprietary PCIe interface) to the motherboard.
Much like Apple handles support calls over the phone, soon only customers within their warranty period will be able to access online chat support through getsupport.apple.com for free. For others, Apple will charge what it refers to as a “pay per incident” fee or require the purchase of an extended warranty through AppleCare. Previously all online support chat features were available for free to users worldwide. Some users might have noticed back in August when Apple revamped its support sites that it started listing a $19.99 per incident fee for chat support. However, up until now AppleCare hasn’t actually been charging users to access the feature.
