The MagSafe power adaptor LED doesn’t appear to indicate the correct activity. The battery does not appear to be charging properly. The computer sleeps or shuts down unexpectedly.

The computer doesn’t respond to the power button when pressed.Ī portable Mac doesn’t appear to respond properly when you close or open the lid. The display backlight doesn’t respond correctly to ambient light changes on Mac computers that have this feature. The Status Indicator Light (SIL) appears to behave incorrectly (on Mac computers that have an SIL).īattery indicator lights, if present, appear to behave incorrectly (on portables that use non-removable batteries). The keyboard backlight appears to behave incorrectly (on Mac computers that have this feature). The computer’s fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.

The computer’s fans speed up quickly and remain at high speed. The companion to the PRAM is the SMC (system management controller) and is only for Intel-based Macs and it stores/manages/controls a lot more interesting things than the PRAM: However, today’s Macs seem to be good to go with a one shot zap, so no worries there. Sometimes, in fact, the machine needed that kind of kick in the pants to clear everything out. Back in the day, we would often let the PRAM zap several times (like 2 or 3) to make sure it was clear. When you log back in, you’ll probably will have to adjust your mouse speed, time and date/timezone, and a few other things, but otherwise you should be good to go.

Let go of the keys and let your Mac reboot normally.

Hold those keys down until your Mac reboots again and you hear the startup chime.

You have to make sure you get those keys pressed before the gray screen comes up or it won’t work.

Press the power button and then press command-option-p-r.

Yes, all the way down, not sleep or logging out. I think I needed to do it over a year ago…and yes, it did fix the problem. Sometimes the PRAM does get wonky, hence why you need to reset it now and again.įor the record, I don’t just reset my PRAM for kicks and giggles. Even back in my beginning tech support days, zapping the PRAM (we were too cool to call it “resetting”) was one of those “okay let’s see if this helps” if the solution to a problem wasn’t obvious. Yeah, this is kind of “core” stuff and sometimes strange values get written there or corrupted or something and weirdness ensues.

Serial Port Configuration and Port definition.Since the dawn of Macs we’ve had what is called the PRAM-parameter RAM (you can say it like pee-ram or pram, doesn’t matter)-which stores stuff like this (from Apple support): It’s a good step to make sure nothing interferes with the resetting process. The good news is that, you’re only a few key presses and reboots away from things (hopefully) being back to normal.įirst, before I get into the hows, whys, and wherefores of resetting the SCM and PRAM, remember…while these are generally safe things to do (and the instructions are freely available on Apple’s support section), make sure you have a recent back up and critical stuff is backed up on an external drive or USB key or something.Īlso I’d disconnect all drives, speakers, external displays and keyboards before you try this stuff.

And while doing stuff like fixing permissions can fix some strangeness, this is strangeness on a deeper level. Yeah, these aren’t problems that simple rebooting often fix.

Is your Mac acting just… odd? Stuff like drives not appearing, screens not adjusting correctly, Bluetooth problems, AirPort non connecting? Maybe your fan is running non-stop or your battery has said that it is 50% charged…for two days…and your MacBook is plugged in.
