Laptop Not Charging After Windows Update: 7 Fixes

Your laptop charged fine yesterday, then a Windows update installed and the battery percentage will not move. Work through the fixes in order, starting with the charger.

Start with the 2-minute checks

An update gets the blame for many faults it did not cause, and a loose charger cable is the most common.

Unplug the charger from the laptop and the wall, then plug it back in firmly at both ends. Check the port and the tip for bent pins, dust, or a loose fit, and try a different outlet. If the charger has a light, check that it comes on.

Next, open Settings > System > Power & battery and read the status line: the exact words point at a different fix.

Symptom	Likely cause	Fix
Plugged in, not charging	Broken battery driver	Reinstall the ACPI driver
Stuck at 50% or 80%	Charge limit on	Turn the limit off
No plug symbol	Charger or port fault	Test another charger
Battery not detected	Driver missing, or dead battery	Reinstall driver, check health
Black screen after the update	Stuck graphics driver	Win + Ctrl + Shift + B
Charges only when off	Charger wattage too low	Match the original wattage

Now check the charge limit. Many laptops cap the charge to protect the battery, and an update can switch it on. On a Surface, Smart charging stops at 80% and Battery Limit at 50%. Other makers use their own apps: Dell Power Manager, Lenovo Vantage, MyASUS, and HP Support Assistant. Turn the limit off to test: if the percentage climbs, the laptop was never broken.

Check the wattage too: it is printed on the charger brick, and the laptop needs at least that much power to run and charge at once. A phone charger may keep the laptop running but never add charge. Borrow a matching charger to test before you buy.

If the charger is dead, match the wattage and the connector on the original charger exactly.

If the quick checks change nothing, the fault is in software. For the same fault with no update involved, read our guide to fixing a laptop battery that is not charging.

Reinstall the battery driver

Windows reads the battery through the Microsoft ACPI-Compliant Control Method Battery driver. The update can leave it broken, so Windows cannot see the battery charge at all. Microsoft’s fix for a Surface that will not charge is to remove this driver and let Windows reinstall it.

After the restart, open Settings > System > Power & battery and watch the status line. The fix worked if it reads “Charging” and the percentage climbs. If the entry is missing, select View > Show hidden devices first. Do not uninstall the Microsoft AC Adapter entry too.

Roll back the update in Settings

If the driver reinstall did not help, remove the update itself. Microsoft says to uninstall an update only when it is causing errors, and this case fits. Uninstalling an update does not touch your files, but it removes that update’s security fixes.

Some updates cannot be uninstalled, and Microsoft says so on the same page. If the update has no Uninstall button, skip to the Safe Mode section. If the fault followed a new Windows version, look in Settings > System > Recovery for Go back, which returns the laptop to the previous version, keeps your files, and is usually available for 10 days.

If the laptop is slow too, our guide to a laptop that is slow after a Windows update covers the matching checks.

Reset the graphics driver and restart cleanly

This step matters when the screen stays black after the update: a black screen can look like a charging fault, while the laptop charges fine.

Press Win + Ctrl + Shift + B together. Microsoft documents this shortcut as a way to reset the graphics driver: you should hear a beep or see the screen flicker if it works. If the picture comes back, save your work and restart, then check the battery status.

A full restart is worth doing on its own: updates leave drivers half-finished, and a restart finishes them. Use Start > Power > Restart and check the battery status first.

Roll back the driver in Safe Mode

Safe Mode starts Windows with only the drivers it needs, which makes it the right place to undo a bad driver update. Use it when the laptop will not charge in normal mode.

The roll back button is greyed out when Windows has no older driver saved. In that case select Update driver instead, or get the driver from the laptop maker’s support site.

Uninstall the update in Windows RE

Windows RE, the Windows Recovery Environment, is the last software step. Use it when you cannot reach Settings, or when the update will not uninstall from inside Windows. To reach it, open Settings > System > Recovery and select Restart now next to Advanced startup, or hold Shift while you select Power > Restart.

If your drive is encrypted with BitLocker, have your recovery key ready: Microsoft warns that some Windows RE tools ask for it. If charging returns, let Windows install the next update when it arrives. Our guide to repairing Windows without reinstalling covers the other tools on the same screen.

When to repair or replace

Software fixes have a limit. Stop here and book a repair if the battery is swollen, the base bulges, or the trackpad has lifted. Do not open the laptop and do not try to charge it: a swollen battery is a fire risk. Stop too if the laptop turns off when you unplug it, if the port is loose or damaged, or if the battery is not detected.

Before you pay for a repair, check the battery health so you can describe the fault to the shop. Our guide to how to check laptop battery health shows how to read the battery report Windows builds for you. If the report shows a worn-out battery, replace it. If it shows a healthy battery that will not charge, tell the shop the steps you tried, in order.

A laptop that shows a battery that is not detected at all needs different checks, since a missing battery points at the battery or the board. Follow that guide first if the battery icon shows a red X.

Mistakes to avoid

1. Buying a new charger before testing the old one. A charger that looks dead may only be loose at the wall, and a new charger will not fix a driver fault. Test another outlet first.

2. Uninstalling every battery entry at once. Removing the AC Adapter entry too muddies the test. Uninstall the ACPI battery entry only, then scan for hardware changes.

3. Rolling back the update before the two-minute checks. A rollback removes security fixes, and it wastes time if the fault is a charge limit or a loose cable. Work in order: charger, charge limit, driver, then the update.

4. Turning off Windows Update so the update never comes back. That leaves the laptop without security fixes. Let the next update install, and check the battery after it.

5. Opening the laptop to test the battery yourself. A swollen battery can catch fire, and opening the base can void the warranty. Take a swollen laptop to a repair shop.

6. Ignoring a charge limit and replacing the battery. A battery that stops at 50% or 80% is usually following a limit in the maker app, not failing. Check the limit before buying a battery.
