One Sunday morning, my laptop powered on—but the battery icon didn’t. Here’s what happened next.
As I usually do when I wake up in the morning—first coffee—I power on my trusty, workhorse of a PC: the Samsung Galaxy Book4 Edge. But this past Sunday, I noticed something was off. The battery icon was missing from the taskbar. So I had to troubleshoot—fast.
I started by checking Microsoft’s support site and searched “battery missing from taskbar.” The instructions were simple enough: go to Settings > Personalization > Taskbar > System Icons, and make sure “Power” is toggled on.
I double-checked the steps, but I quickly realized that without a battery icon, the “Power” option wouldn’t even appear in Settings.
That’s when I checked Device Manager. Under the “Batteries” section, I only saw one item: Microsoft AC Adapter—which represents the power brick. The internal battery driver, typically labeled Microsoft ACPI-Compliant Control Method Battery, was nowhere to be found.
So I turned to a trusted partner in my tech troubleshooting toolkit—ChatGPT.
I asked why the ACPI battery driver was missing. The answer: if Windows doesn’t detect the internal battery, the driver won’t appear. That would also explain the missing battery icon and missing “Power” toggle. I learned that possible causes might include faulty firmware or a communication issue between the embedded controller and Windows.
Following the suggestion, I restarted the PC and tapped F2 to enter the BIOS. Under Advanced, I found and ran Smart Battery Calibration. Then I stepped away and waited—for about five hours—while the system slowly drained to 0%.
When the system finally shut off, I plugged in the power adapter and rebooted, fingers crossed. I launched Device Manager and checked the Batteries section.
Still no ACPI-Compliant Battery.
After all that troubleshooting, I knew I had to escalate. I submitted a repair request through Samsung’s website, printed the UPS shipping label, and brought my beloved Galaxy Book4 Edge to my local shop for shipment.
Now I wait—eagerly—for its return. And hopefully, when I power it on again, I’ll be greeted with that familiar battery icon right back where it belongs.
