MacBook Air Power-On Pads – Location & Use
They go by “jumper pads”, “short-circuit pads”, “power pads”, and “power-on pads”. Whatever you call them, there are two bits of metal on your MacBook logic board that can force your laptop to boot up, even if the power button won’t do the trick.
My MacBook Air doesn’t turn on
Is it the power button? Logic board? Something else?
If your MacBook won’t power on, there’s an easy way to determine if the problem lies with the power button or with another component in the laptop. Apple was generous enough to design an integrated method for bypassing the power button on all MacBook logic boards. Below I’ll show you how to use the power pads, as well as provide high-res reference photos of the locations of these power pads on each individual release of the MacBook Air.
We’ve talked about this topic before on the Beetstech Blog; last time covering the MacBook Pro Unibody product line. If you’re looking for power on pad info for the MacBook Pro Unibody models follow this link.
Why use power on pads?
There are lots of reasons why your MacBook Air might not turn on, and this procedure only rules out a single, but very common root cause. The power button is connected to the logic board via the same 30-pin cable as the rest of the keyboard, and of those 30 pins, only two are necessary for the signal to travel from the power button to the logic board. There are probably quite a few ways you could damage this connection if you’re creative enough, but we typically find that either corrosion from a liquid spill damaged the logic board’s keyboard connector, or the keyboard flex cable was damaged from repeatedly attempting to insert the cable. Diagnosing Apple hardware issues is a simple process of elimination, and bypassing the keyboard allows you to at least rule out one component.
How do I use the power pads?
Tools Needed
- The proper screwdriver to remove bottom case screws for your particular model.
- A paperclip with electrical tape on the area you will hold (to act as an insulator) or a flat head screwdriver.
Steps
- Remove the bottom case.
- Don’t forget to protect your computer from ESD discharge by grounding yourself ahead of time.
- Disconnect the power adapter and battery. Connecting/disconnecting other cables while power is connected can cause damage.
- Disconnect the keyboard cable from your logic board. This step is very important! If you leave the keyboard plugged into the logic board, the power pads won’t work.
- Now that the keyboard cable is disconnected, plug the battery in again.
- Locate the power-on pads using the reference pictures below.
- Use the paper clip or flat head screwdriver to bridge the connection with the 2 power-on pads. Maintain the bridge for a maximum of three seconds.
- If the fan doesn’t start spinning after 10 seconds, then reattempt the bridge between the power-on pads.

High Sierra and Testing RAM
With macOS 10.13, otherwise known as High Sierra, Apple introduced an ambitious EFI update. Several of the changes include: the introduction of the Apple File System, support for NVMe drives, and the usual batch of security updates. However, these EFI updates can cause some unwanted behavior when you test your Apple computer’s memory. At Beetstech, we use a long-time industry standard, MemTest86 to perform a comprehensive test of each computer’s RAM.
But never the type to blindly accept test results, strange testing outcomes led us to discover a bug in MemTest86 affecting computers running the new EFI firmware. In short, the newly updated EFI causes MemTest86 to incorrectly fail certain tests. But there is good news: while normal operation of MemTest86 is limited under these new EFI updates, we also discovered some simple workarounds for testing your Apple’s memory in MemTest86.
So let’s dive into how we discovered the MemTest bug, devised a reliable work-around, and get into some nitty gritty details of MemTest86 operation.

OEM MagSafe Chargers vs Cheap Imposters: Teardown for Truth
Anywhere premium products are produced, there are unsavory folks trying to make a quick buck selling cheap knockoffs. It happens in every industry, from clothes to food to tech. But in recent years, counterfeit electronics have surpassed nearly all other categories of counterfeit goods by dollar value, and Apple, being the de facto high-end electronics manufacturer, makes for a prime target.
But you’d never be caught buying counterfeit electronics, because you can tell the difference, can’t you?
The Ultimate Guide to Apple’s Proprietary SSDs
Remember the good ol’ days of carrying a spare battery, upgrading your own RAM, maybe even adding a second hard drive? If you’re an Apple user, those luxuries may be behind us, but upgrading your own solid state drive is still a privilege the Apple overlords allow us to have, for now that is.
Despite retaining the ability to upgrade your own SSD, ever since Apple introduced their proprietary “blade” SSDs in 2010, the task hasn’t been as simple as it once was. Apple talks up read and write speeds, but they rarely dive into the nitty gritty details of the technology behind the SSDs they use — drives specially designed only for Apple computers.
After countless questions, both from customers and our own staff, we decided to start our own investigation into the hardware involved. You have to be a bit of a private eye to uncover the secrets behind these drives, and the deeper we looked, the more surprises we found.
Your Hard Drive Cable Is A Ticking Time Bomb
Owners of a Unibody MacBook Pro laptop are probably already aware that failure of the hard drive flex cable is a common issue. While it affects just about the entire Unibody lineup, the Mid 2012 MacBook Pro 13″ (Model A1278) is especially prone to this type of failure.
What is it that makes the Mid 2012 release special in this regard? A design flaw in the flex cable that seems to be compounded by the properties of the aluminum housing.
Our repair services department noticed this issue when they’d replace a bad cable, only to have the customer return a few months later with another bad cable. And possibly again with yet another bad cable. It didn’t matter if we used a used cable or a new cable in the replacement. Customers kept returning with the same persistent issue. We had to figure out what was causing the issue and find a solution.
Great quality pictures. Really useful info.
Your pictures helped me figure out my keyboard was all that was the wrong. I cleaned my motherboard with alcohol just to be sure. But I just bought a new top case with keyboard (from you guys) instead of paying the Apple store to repair the whole thing. You rock!
Hey everyone. pls help with the repair. macbook Air early 2015 does not turn on from the battery, only from the adapter. tried to change the battery – the same result. maybe someone has a diagram or someone will tell you what to check
Doesn’t work
MacBook Air 2017 model won’t turn on,,, help
worked for me 😊 thank
Thank you for your page. I was working on a macBook Air A1466 Early 2015 without keyboard. So with your suggestion I was able to switch on and test the motherboard. I didn’t find this kind of solution anywhere else!
I am looking everywhere for the Macbook air a1466 2015 power pods. I took it apart trying to find them. Still dont know where they are. Perhaps a little more guidance to locate them, near a usb port or fan etc. For older models i have no problem finding them. Thank you!
