I’ve used thousands of laptops over the years, between testing and trade shows, so it isn’t often that an issue pops up that I haven’t encountered before. But that’s exactly what happened recently while working with Acer’s Swift Go 16 AI (review coming soon). This unassuming mid-range portable packs AMD’s Gorgon Point silicon, alongside a large IPS screen and a roomy 7-inch touchpad – nothing groundbreaking, but a solid, svelte system with a metal shell and an affordable price (at least when it’s on sale).But pretty quickly, when I started setting it up and photographing it, I noticed that the screen would often go black, briefly, when I tried typing, and I would then get kicked out to the Windows lock screen. Since I was using a local account with no password to type in, this was only a minor annoyance at first. But it kept happening – not every time I tried to use the laptop, but often enough that I pretty quickly decided that the review unit must be faulty. Eventually, I reached out to Acer to explain and show them the problem.Company engineers thought it might be a software conflict, and suggested I reset the system, which I did, to no avail. The screen was still flashing black and kicking me out to the lock screen. In fact, after some experimenting, I could sometimes make the issue occur when I was barely even touching the touchpad. I discussed it with colleagues, sent them the same video I had sent to Acer, and became convinced it was some kind of strange electrical fault with the touchpad. I eventually got a second review unit of the laptop, but by that time I was onto other priorities, so it sat for a week or so, until I decided to at least bring the original “faulty” laptop back to the office so I could box it up and return it to Acer.Before I boxed it up to send back to Acer for their evaluation, though, I decided to show another colleague, Tom’s Guide’s lab tester Arif Bacchus, in our New York office. He watched me demonstrate the problem for about ten seconds before casually suggesting, “I think it might be your watch.”This hadn’t even occurred to me, but as soon as he said it, everything started to fall into place in my mind. I had been wearing my Galaxy Watch 7 this and every time I had the issue, because I wear my watch pretty much whenever it isn’t charging. And my watch band (which Amazon tells me I’ve had since May of last year) has a magnetic clasp on the bottom, which sits a few inches behind my right wrist when I’m wearing it. And as I moved my wrist across the lower-right edge of the laptop, the screen went black for a second, and I was once again kicked back to the Windows lock screen.The touchpad was never the issue, and the laptop isn’t faulty – although it does have a lid sensor that is triggered by a magnet embedded in the upper-right bezel, which can also be triggered by most other magnets if they get close to the bottom-right of the deck. I was able to duplicate the issue with a fridge magnet, a magnetic Qi 2 accessory, and a borrowed Apple Watch, which also had a band with a magnetic clasp.
