Hi Copilot , is there a way I can trigger an alarm on my INTEL-based Windows 10 Laptop so that when my Windows 10 Laptop battey is FULLY CHARGED or 100% charged , IT WILL TRIGGER AN ALARM or IT WILL TRIGGER A RINGING TONE so that I can disconnect the Laptop Charger from my Windows 10 Laptop ?? Copilot , is it very difficult to do this or does it require a lot of programming effort to do so ? Copilot , how come the Laptop manufacturer NEVER THOUGHT OF THIS BEAUTIFUL IDEA because the Laptop has been around with us on this Planet for so long and for so many years ? Could you please give some thoughts on this ! This is the same case for 5G smartphones , too , and how come the 5G smartphone manufacturer NEVER THOUGHT OF THIS BEAUTIFUL IDEA because the 5G smartphone has been around with us on this Planet for quite some time , too ? Copilot , could you please shed some light on this matter ? THANKS.
MICROSOFT Copilot Answer
Great question — you’ve touched on a surprisingly overlooked feature in both laptops and smartphones. Let’s break it down:
🔔 Can You Trigger an Alarm at 100% Battery on Windows 10?
- Built-in Windows limitation: Windows 10 does not include a native feature to play a sound when your battery reaches 100%. It only warns you when the battery is low.
- Possible workarounds:
- Third-party utilities: Apps like Battery Alarm, BatteryCare, or Full Battery & Theft Alarm (for phones) can notify you when charging is complete.
- Custom scripts: With a bit of programming (using PowerShell or Python), you can monitor battery percentage and trigger a sound when it hits 100%. This isn’t very difficult — it’s a few lines of code that check battery status every minute and play a sound file.
- Task Scheduler + Script: You can set up Windows Task Scheduler to run a script that checks battery level and plays a tone when full.
So, technically it’s not hard — but it requires either third-party software or a DIY script.
🏭 Why Manufacturers Haven’t Added This Feature
- Design philosophy: Laptop and phone makers assume users will leave devices plugged in. Modern batteries and charging circuits are designed to stop charging at 100% and switch to “trickle” or “maintenance” mode, so they don’t overcharge.
- User experience: Manufacturers prioritize simplicity. Adding alarms might be seen as intrusive or unnecessary for most users.
- Battery management focus: Instead of alarms, companies focus on features like battery health modes (e.g., Lenovo’s “Conservation Mode,” Dell’s “Battery Preservation,” Apple’s “Optimized Battery Charging”) which automatically stop charging at ~80% to extend lifespan.
📱 Smartphones and the Same Issue
- No native alarm: Just like laptops, phones don’t notify you at 100%.
- Third-party apps: On Android, apps like AccuBattery or Battery Alarm can do this. On iOS, Apple restricts background monitoring, so it’s harder to implement.
- Reasoning: Again, manufacturers rely on smart charging circuits and battery health features rather than alarms.
✨ My Thoughts
You’re right — it is a beautiful idea. It’s not technically difficult, but it hasn’t been prioritized because:
- Modern batteries are safe to leave charging.
- Manufacturers prefer automated battery management over manual user intervention.
- They assume most users don’t want extra notifications.
But for power users who care about battery longevity, alarms or charge-limit settings are very useful. That’s why third-party developers have stepped in to fill the gap.
✅ Recommendation: If you want this feature on your Windows 10 laptop, the easiest path is to install a free utility like Battery Alarm or write a simple PowerShell script. On smartphones, apps like AccuBattery (Android) can help.
Would you like me to show you a step-by-step PowerShell script that plays a sound when your laptop battery hits 100%? That way you wouldn’t need extra software.
