Your Mac should still be able to turn on with a dead battery. As long as you have power going coming from the charger, it's more than enough to both power up and charge your Mac. You have three possibilities for the cause of this: MagSafe Board (highest probability). This board is known to go bad and when it fails, it presents symptoms similar to what ...

Even if your battery is dead, your computer should still switch on, see this article for more details. Might be power cables inside your laptop. You can test with voltage meters, if you don't know how it works, you can always go to an electrician or just take it into a computer shop or even Apple.

The battery appears to be dead or damaged. I would go to an Apple Store to have it replaced. But It is still strange that even with the power cable connected it does not turn on. Another test you could do is resetting the PRAM by holding Command + Option + P + R and turning on the MacBook

You can also try bypassing that port entirely and just use a USB port with an adapter like "Cable Matters SuperSpeed USB 3.0/2.0 to HDMI/DVI Adapter for Windows and Mac up to 2560x1440 in White" https://www.amazon.com/gp/product/B004MS0DIK/

You can definitely buy the requisite parts aftermarket - DigiKey would be the first place I would look. You could also remove the parts from another rMBP (e.g. flood damaged or something). You can probably do the modification without damaging other things on the board, but it would be difficult. You are not going to do it at home. You're going to need ...

I don't think this will be possible. The board will be manufactured with only that size of memory in mind, so the memory controller or other hardware would have to be changed too, and its not like there will be place for more memory chips. One exception I can think of is if some higher model has more memory, then there might be some unpopulated place for ...

The short answer is yes (anything is possible), but is it feasible? There's a ton of responses out there whether you can/cannot resolder memory chips to Apple logic boards in an attempt to upgrade RAM. Unfortunately, there is a lot of mis-information out there. Basically, they all revolve around one of the following three themes: It's extremely ...

Without knowing which i7, how much RAM, and what type of internal storage your 2013 system and the 2015 system you're looking at has, I can't really compare the performance of the machines. If you replace your old machine with a 2015 i7 and with at least the same amount of RAM and the same type of storage, the new one will be noticeably faster, particularly ...

MBP early 2011 model w/ SSD, Mavericks OS. Allowing shutdown due to out of battery power, I had this twice, with different fixes: SSD was trashed, un-recoverable. Replaced SSD, restored my backup. Back to normal. I fixed it myself; re: iFixit.com repair manifesto Booting from backup would not complete startup (or appeared not to). Cause: Bad video card. ...

Unfortunately peripheral connections are simply something that isn't logged by your Mac. Just think - why would it need to keep a written log of when a USB drive is plugged in? Hope you end up finding it again!

Try parsing the output of the ioreg command. I tried ioreg -l | grep PCI and got a bunch of info.

I am assuming that you are referencing a 27" Late 2013 iMac because there is no 21" iMac that has that specific CPU frequency. You can have up to two external displays connected via Thunderbolt according to the specs posted on EveryMac.com I have used 30" and 43" displays with my iMac and there has been zero lag. I also only have SSDs (no hard drives) ...

...reattaching the cables in the electronics of the computer. I am assuming by this statement, you have opened up your Macbook for whatever reason. Did you do any sort of service? Try reseating the Airport adapter - remove it completely and reinstall it. There are 4 cables that go to this adapter. Three are the antenna cables (J0, J1, and J2) and ...

If you end up with option 3. Screw extractors, then your 'cheap choice' to put it back together is just make a saw cut in the top of the screw [remains] & treat it as a standard flat-blade screw-head from then on in. I presume you have one of those, but didn't procure the necessary Torx before starting out ;-) Don't try saw-cutting it first... you ...
