HP charging light blinking
Why is my HP laptop charging light blinking orange and white and not charging?

Short answer
On HP machines that alternating flash is a deliberate signal, not a random fault. It usually means the laptop has spotted a problem with the power supply or the battery: a charger that cannot deliver enough watts, a battery whose cells have drifted out of balance, or a battery the firmware no longer trusts. A drained or confused power controller shows the same pattern, which is why a hard reset fixes a good share of them. The quickest thing to try first: do a hard reset to clear the power controller — Shut the laptop down, unplug the charger and remove the battery if yours comes out. Hold the power button down for a full thirty seconds with nothing connected. Put the battery back, plug the charger in on its own and start it up. This is HP's own first step and it clears a stuck charging controller more often than people expect. Most people are done in about 20 minutes.

Sounds like this
- •The light by the charging port flashes between orange and white
- •The battery percentage does not move even after an hour
- •It sometimes runs fine from the charger but will not fill the battery

Do a hard reset to clear the power controller
Shut the laptop down, unplug the charger and remove the battery if yours comes out. Hold the power button down for a full thirty seconds with nothing connected. Put the battery back, plug the charger in on its own and start it up. This is HP's own first step and it clears a stuck charging controller more often than people expect.

Check the charger is the right one
Look at the wattage printed on the brick and compare it with the sticker on the underside of the laptop. A 45 watt charger on a machine that wants 65 watts will run it but refuse to charge, and a USB-C phone charger will do the same. Try a known good HP charger of the correct wattage before assuming the battery is dead.

Run HP's own battery test
Restart and tap Escape as it starts, then press F2 for HP PC Hardware Diagnostics. Choose Component Tests, Power, Battery. The result is plain: Passed, Calibrate or Replace. If it says Replace, no software fix will help and you need a new battery. If it says Calibrate, let the tool run its cycle, which takes a couple of hours.

Reinstall the battery driver
Open Device Manager, expand Batteries, right click Microsoft ACPI-Compliant Control Method Battery, choose Uninstall device, then restart. Windows puts it back and the charge reading often corrects itself. Leave the ACPI adapter entry alone.

Update the BIOS and the HP power software
Go to HP Support Assistant or the HP support page for your model and install the latest BIOS and chipset updates. HP has released BIOS fixes specifically for charging faults on several ranges. Keep the charger connected throughout a BIOS update and do not switch it off part way.

Clean the port and check the cable
Shine a torch into the charging socket and remove any lint with a wooden toothpick. Bend the last few centimetres of the cable while watching the light; if the flashing changes, the cable is broken inside and needs replacing.

Read the flash pattern if it is a different rhythm
HP uses a coded pattern on some models. Count the flashes of the caps lock or power light at start up: a repeating group of three or five points at memory or graphics rather than the battery. Write the pattern down before phoning support, because it tells them the fault immediately.
If none of that worked
If the battery test says Replace, buy the battery for your exact model number, and prefer a genuine HP part. Cheap copies often fail the firmware check and produce the same flashing light straight out of the box.
