Apple Watch是一款功能强大的产品，但一些Watch用户(Watch)遇到了侧边按钮（不是数字表冠）卡住或不起作用的问题。
发生这种情况的原因可能有多种，因此，修复Apple Watch侧边按钮不再起作用的方法也各不相同。尝试这些故障排除提示，立即找出问题所在。
如果您的 Apple Watch 无法开机
如果您的Apple Watch屏幕卡在黑色图像上并且无法打开，您可能会认为侧边按钮有问题。但是，还有其他几个原因导致按下侧边按钮（充当电源按钮）可能不会像往常一样显示Apple标志。
首先，如果电池电量耗尽，(First)手表(Watch)可能需要几个小时才能充满电来初始化屏幕并启动。假设您使用的是已知良好的充电器，请让手表充电一整夜，然后重试。
您的Apple Watch(Apple Watch)电池也可能有问题。如果您仍在标准保修期内或拥有Apple Care Plus，您可以免费更换电池。即使您不是，Apple 的电池更换标准价格也是相当合理的。
检查软件更新
您的侧边按钮无法使用的一个可能原因可能是当前版本的WatchOS中存在错误。在这种情况下，值得检查更新。为此，最好将手表放在充电器上。
在 iOS 上的Watch应用程序中，转到“General > Software Update”，如果有可用更新，请选择“下载(Download)并安装(Install)” 。
强制重启手表
检查侧键故障是否由软件问题引起的快速修复方法是强制重启手表(Watch)。这不会擦除您的数据或任何类似的永久性内容。这是将Apple Watch从黑屏、软件故障或挂起的应用程序中抢救出来的好方法。
您可以通过同时按住数字表冠和侧面按钮来启动硬重启。按住这些按钮 10 秒钟或直到出现Apple标志。
现在，如果您的侧边按钮无法关闭手表电源，(power off the watch)这似乎不是有用的建议。但是，您可能会发现，即使侧面按钮在应用程序或WatchOS中通常不起作用，强制重启也有效。如果您可以通过这种方式成功重启手表，则表明该按钮没有问题！如果这没有启动强制重启，则这是一个很好的线索，表明该按钮存在物理问题。
一滴水
对于许多遇到按钮卡住的Apple Watch用户来说，在侧边按钮的边缘周围滴一滴水似乎很管用。这个想法是，水会溶解水蒸发产生的任何粘性物质或残留物质，从而使按钮可以自由移动。按钮和表体之间的公差很小，所以这是有道理的，尝试一下也没什么坏处。
温暖的自来水
如果一滴水不起作用，您可以尝试在手表按钮上浇温水，同时反复按下以达到相同的效果。水不应该太热，因为高温可能会损坏您的手表，水流也不应该太猛。
尽管Apple Watch Series 2及更新机型的额定浸水深度可达 50 米，但这并不意味着它们能经受住强烈的水柱喷射，所以请放轻松！
这里的想法是，除了一些水之外，一些堵塞按钮的粘性物质可能会随着一点点热量而溶解。
使用软牙刷
我们已经看到一些Apple Watch用户声称使用软毛牙刷或其他合适的牙刷取得了成功。细毛到达按钮和表体之间的空间，清除粘性物质。小心不要使用可能会划伤手表机身的刷子！
使用喷水模式
Apple Watch有一个特殊的功能，可以从扬声器中喷出水，这也会强烈震动整个手表。在某些情况下，这似乎也有助于解决按钮卡住的问题。
从表盘底部向上滑动(Swipe)，然后点击水滴按钮。
按住数码表冠直到喷水模式启动，然后等待它完成并再次尝试使用侧面按钮。
凹陷纽扣
如果您的侧面按钮明显凹入手表中，则用于将其推回中立位置的机制可能已损坏。在这种情况下，您应该将其带到Apple进行评估。对此没有简单的解决方法，因此请准备好更换。
取消与 Apple Watch 的配对
如果硬重置没有帮助，并且其他快速修复似乎都不起作用，那么下一个稍微更激烈的方法是取消配对您的手表。这将擦除手表本身的数据，但只要它最近与您的 iPhone 同步（不支持iPad(iPads)），您的所有信息都是安全的，并且会在您再次配对设备时恢复。
- 将 Watch 置于 iPhone 范围内，打开Apple Watch应用程序。
- 选择我的手表(My Watch)选项卡，然后选择所有手表(Watches)。
- 选择相关手表(Watch)旁边的信息按钮。
- 现在选择取消配对 Apple Watch。
如果您有Apple Watch蜂窝网络型号，您会收到一条消息，询问您是否要从手表中移除蜂窝网络套餐。如果你要换一部新的 iPhone 或另一块手表，你会想要这样做。由于我们要在取消配对后再次配对手表，所以选择保留计划。
取消配对过程完成后，您应该会看到配对提示，就像手表是新的一样。因此，请按照您首次设置手表时的操作进行操作。
我的 Apple Watch(My Apple Watch)液体损坏(Liquid Damage)怎么办？
尽管Apple Watch Series 2及更新型号的手表型号被评为防水，但这并不意味着它们不受水的影响。重要的是要记住，防水 IP 等级并不意味着所有人都可以免费使用。
盐水(Saltwater)、脏水、水射流、液体密封件磨损以及运气不佳都可能导致液体进入。无论发生什么情况，按钮都会停止工作，这通常是液体腐蚀的迹象。
遗憾的是，这也意味着液体很有可能进入了智能手表的内部。因此，当您让技术人员打开它时，结果可能是无能为力。更糟糕的是，大多数类型的液体损坏不在标准保修范围内。
卡住的数码表冠怎么办？
上面的大部分建议修复同样适用于 Apple Watch 的数字表冠(Digital Crown)和侧边按钮。虽然表冠的机械结构更为复杂，但残留物和粘性物质仍可能是故障的原因，甚至可能更甚。
联系Apple 支持(Apple Support)或前往Apple Store
如果您的 Watch 似乎有硬件问题，您无法通过上述任何提示解决，请将其带回Apple进行评估。事实上，如果您的Apple Watch仍在标准或延长保修期内，请将其取回，而不要尝试自行修理。
像侧面按钮损坏这样的问题的手表(Watch)维修似乎并不常见，因此您很有可能只需在保修期内获得更换部件。
Is Your Apple Watch Side Button Stuck or Unresponsive? Try These Fixes
The Apple Watch is a robust product, but some Watch owners have encountered an issue with the side button (not the digital crown) sticking or not working.
There are a few different reasons why this might be happening and, as such, different ways to fix Apple Watch side buttons that don’t play ball anymore. Try these troubleshooting tips to figure out the issue in no time.
If Your Apple Watch Won’t Turn On
If your Apple Watch screen is stuck on a black image and won’t turn on, you may conclude that the side button is the issue. However, there are several other reasons why pressing the side button (which acts as a power button) may not make the Apple logo appear as usual.
First of all, if the battery has been drained too much, it can take a few hours before there’s enough charge in the Watch to initialize the screen and boot up. Assuming that you’re using a known good charger, leave the watch to charge overnight and try again.
You may also have a faulty Apple Watch battery. If you’re still within the standard warranty or have Apple Care Plus, you can get the battery replaced for free. Even if you aren’t, Apple’s standard price for a battery replacement is quite reasonable.
Check for Software Updates
One possible reason your side button may not be working may be the result of a bug in the current version of WatchOS. In this case, it’s worth checking for an update. It’s a good idea to have your watch on its charger for this.
In the Watch app on iOS, go to General > Software Update, and if an update is available, select Download and Install.
Force Restart Your Watch
A quick fix to check whether your side button woes are from a software issue is to do a forced restart of your Watch. This won’t wipe your data or anything permanent like that. It’s a great way to snap an Apple Watch out of a black screen, software glitch, or a hanging app.
You can initiate a hard reboot by pressing and holding the digital crown and side button together. Hold these buttons for 10 seconds or until the Apple logo appears.
Now it may seem like it isn’t helpful advice if your side button isn’t working to power off the watch. However, you may find that a forced restart works even if the side button doesn’t work in apps or WatchOS in general. If you can successfully restart your watch this way, it’s a sign that the button is physically fine! If this doesn’t initiate a forced restart, it’s a good clue that the button has a physical problem.
A Drop of Water
Rubbing a drop of water around the edges of the side button seems to work for many Apple Watch users experiencing a stuck button. The idea is that the water will dissolve any gunk or left-over material from water evaporation, freeing the button to move. The tolerances between the button and the watch body are quite small, so it makes sense, and there’s little harm in trying it.
Warm Running Water
If a single drop of water doesn’t do the trick, you can try running warm water over the watch button while pressing it repeatedly to achieve the same result. The water should not be hot since high temperatures may damage your watch, nor should the stream be strong.
Although Apple Watch Series 2 and later models are rated for immersion up to 50 meters, that doesn’t mean they’ll stand up to a strong jet of water, so take it easy!
The idea here is that some of the gunk jamming up the button might dissolve with a little bit of heat in addition to some water.
Use a Soft Toothbrush
We’ve seen a few Apple Watch users claim success using a soft bristle toothbrush or other suitable brush. The fine bristles reach the space between the button and the watch body, clearing out the gunk. Be careful not to use a brush that might scratch the watch’s body!
Use Water Ejection Mode
The Apple Watch has a special function to eject water from its speakers, which also strongly vibrates the entire watch. In some cases, this seems to help with a stuck button as well.
Swipe up from the bottom of the watch face, and then tap the water droplet button.
Press and hold the digital crown until water ejection mode is activated, then wait for it to finish and try using the side button again.
Sunken Buttons
If your side button is visibly sunken into the watch, the mechanism that’s meant to push it back into its neutral position is likely broken. In this case, you should just take it to Apple to have it assessed. There’s no easy fix for this, so be prepared for a replacement.
Unpair Your Apple Watch
If a hard reset doesn’t help, and none of the other quick fixes seem to work, then the next slightly more drastic method is to unpair your watch. This will erase the data on the watch itself, but as long as it’s recently synced with your iPhone (iPads are not supported), all of your information is safe and will be restored when you pair the device again.
- With your Watch in range of your iPhone, open the Apple Watch app.
- Select the My Watch tab, then All Watches.
- Select the info button next to the Watch in question.
- Now select Unpair Apple Watch.
If you have a cellular model of Apple Watch, you’ll get a message asking if you want to remove the cellular plan from your watch. If you were moving to a new iPhone or a different watch, you’d want to do this. Since we want to pair the watch again after unpairing it, choose to keep the plan.
Once the unpairing process is complete, you should see the pairing prompt as if the watch was new. So proceed as you did when you first set up the watch.
What About Liquid Damage to My Apple Watch?
Although Apple Watch Series 2 and later watch models are rated as water resistant, this doesn’t mean they’re immune to the effects of water. It’s important to remember that a water-resistant IP rating doesn’t mean a free-for-all.
Saltwater, dirty water, water jets, wear on the liquid seals, and just plain bad luck can lead to liquid ingress. A button that stops working no matter what is often a sign of corrosion caused by liquid.
Sadly this also means there’s a decent chance that liquid has made it into the internals of the smartwatch. So when you get a technician to open it up, it may turn out that there’s nothing that can be done. What’s worse, most types of liquid damage aren’t covered by the standard warranty.
What About a Stuck Digital Crown?
Most of the suggested fixes above apply equally to the Apple Watch’s Digital Crown as it does to the side button. While the crown is more mechanically complex, residue and gunk can still be the reason for malfunctions, perhaps even more so.
Contact Apple Support or Go to the Apple Store
If your Watch seems to have a hardware issue you can’t fix with any of the tips above, take it back to Apple for an evaluation. In fact, if your Apple Watch is still under the standard or extended warranty, take it back without trying to fix it yourself.
Watch repairs for issues like a busted side button don’t seem that common, so there’s a good chance you’ll simply get a replacement unit under warranty.
