I have a 1st generation Time Capsule that always used to work fine, but recently it shuts down almost only seconds after I turn it on.
How can I solve this ?
Most of the time, this problem can be solved rather easily.
The cause could be a broken HardDrive inside your Time Capsule (if that’s the case, go here to see instructions on how to replace the HD), but most of the time this specific problem turns out to be an overheated (and therefore broken) power unit.
Even though this type of Time Capsule is marked obsolete by Apple, it will still function in your current WiFi network and can still be configured using the current AirPort Utility app version 6 and newer.
The main problem is probably not going to be to replace the power unit, but finding a new power unit. You might find one on Amazon, but since it will probably be a secondhand item, your will probably have more luck searching for an “A1254 power unit” on eBay, AliExpress or Google Shopping
When you have found a new (secondhand) A1254 power unit, you can build it into your A1254 “1st generation” Time Capsule this way :
put the Time Capsule upside-down and use a hairdryer to heat up the rubber base plate and loosen it’s glue (if you don’t do this, you will probably rupture the base plate when you try to take it off)
then follow the iFixit manual for replacing the power unit and make sure not to skip the important comment at Step 2 : “The two screws in the top center of this picture should not be removed at this time. They are locating pins on the hard drive.”
after taking out the broken power unit and putting in the new (secondhand) power unit in, put your Time Capsule back together doing the iFixit steps in reverse order
after plugging the Time Capsule into the power, you can reinstall it into your WiFi network using the AirPort Utility app on your Mac (or on your iPhone/iPad)
I had left my MacBook Pro (Late 2008 running OSX 10.11 El_Capitan) running and had forgotten all about it… after completely recharging everything seemed to be okay on first sight, but it turned out that even though I could use the (internal) trackpad to move the cursor, I wasn’t responding at all to any clicking on it. I therefore had to connect a USB-mouse. Even after restarting, the trackpad was responsive to moving the cursor, but not to clicking…
Is my MacBook’s trackpad broken ? Or is there a software solution I could try ?
Even tough it’s not possible to completely rule out the scenario that your trackpad is broken, chances are you will be able to get it working properly again by an action that is normally referred to as “Resetting the PRAM”. Here’s how to do that :
shut down your MacBook
take out all cables and USB-sticks (this is just to rule out complications)
restart your MacBook using the POWER-button
immediately press and hold the key-combo [CDM]+[ALT]+[P]+[R]
make sure you do so while the screen is still black
when the screen lights up in light grey, you’ll hear the startup-chime
now release all your fingers from the keyboard before the Apple-logo appears
let your MacBook startup fully, then test if all works as expected
then reconnect any cables and USB-sticks needed
Note : no worries if you act too slowly or too quickly ; if you are too late to press the key-combo, just let your MacBook startup, then shut down and try again ; if you keep pressing the key-combo for too long, you will hear the startup-chime multiple times (you will have reset your PRAM multiple times, but that’s no problem) so just release the keyboard, and just let your MacBook startup and you’re done… 😉
