If your Xiaomi RedmiBook Pro 15 battery is not charging, you may see symptoms such as:
- “Plugged in, not charging”
- Battery stuck at 0% or 1%
- Battery percentage not increasing
- Laptop shutting down when the charger is removed
- Battery charging only up to a certain percentage
- Laptop not detecting the battery
- Battery draining quickly even while charging
The good news is that a charging problem does not always mean that the entire laptop has a serious hardware failure.
In many cases, the cause may be the charger, charging port, software, or the battery itself.
This guide explains the most common causes of Xiaomi RedmiBook Pro 15 battery charging problems and how to identify when the battery needs replacement.
1. The Battery Has Reached the End of Its Usable Life
Laptop batteries naturally lose capacity over time.
After many charging cycles, the battery may no longer be able to store enough energy. Eventually, you may notice:
- Very short battery runtime
- Battery percentage dropping rapidly
- Laptop shutting down immediately after unplugging
- Battery stuck at a particular percentage
- Battery not charging properly
If your laptop works normally with the charger connected but shuts down immediately when you unplug it, the battery may have significantly degraded.
For compatible Xiaomi RedmiBook Pro 15 models, the replacement battery may be identified by part numbers such as:
R15B02W, R15B0ZW, and 4ICP6/68/73.
If your battery is confirmed to be faulty, you can check the R15B02W Xiaomi RedmiBook Pro 15 replacement battery and verify the specifications before ordering.
2. The Battery Is Stuck at 0% or 1%
A battery that remains at 0% or 1% while the laptop is connected to the charger may indicate a battery or charging problem.
Possible causes include:
- Severely degraded battery cells
- Battery protection circuit activation
- Battery communication issue
- Faulty charger
- Internal battery connection problem
What You Can Try
- Shut down the laptop.
- Disconnect the charger.
- If possible, allow the laptop to remain powered off for a few minutes.
- Reconnect the charger.
- Start the laptop and check the battery status.
If the battery repeatedly remains at 0% or 1%, it may require professional testing or replacement.
3. Windows Shows “Plugged In, Not Charging”
This is one of the most common laptop battery problems.
The message may appear when:
- The battery has reached its maximum charge
- Battery protection software is limiting charging
- The battery is severely degraded
- The charger is not delivering sufficient power
- The battery is not communicating correctly with the laptop
First, check whether the battery percentage increases after leaving the laptop connected to the charger for some time.
If the percentage never increases, the battery and charger should be tested.
4. The Charger or Charging Adapter May Be the Problem
A battery may appear to be faulty when the actual problem is the charger.
Check whether:
- The charger is the correct charger for the laptop
- The charger connector is damaged
- The charging cable is loose
- The adapter becomes unusually hot
- The laptop charger is delivering the correct power
If the charger cannot provide sufficient power, the battery may not charge correctly.
Important
A replacement battery will not solve a charging problem caused by a faulty laptop charger or motherboard charging circuit.
This is why proper diagnosis is important before replacing the battery.
5. The Battery Connector May Be Loose
Inside the laptop, the battery connects to the motherboard using a dedicated connector.
A loose or improperly connected battery cable can cause:
- Battery not detected
- Battery not charging
- Laptop working only with the charger
- Sudden shutdowns
If the laptop has recently been opened for repair, cleaning, SSD upgrade, RAM upgrade, or other service, the battery connection should be checked.
⚠️ Always disconnect the charger before opening the laptop.
6. Battery Driver or Software Problems
Sometimes Windows may not correctly communicate with the battery.
You can try reinstalling the battery-related device drivers.
Basic Windows Troubleshooting
- Open Device Manager.
- Expand Batteries.
- Locate the battery-related entries.
- Uninstall the battery device driver.
- Restart the laptop.
Windows may automatically reinstall the required driver after restarting.
This can help if the issue is caused by a temporary software or device recognition problem.
However, driver troubleshooting will not restore battery capacity if the battery cells themselves are worn out.
7. The Battery May Be Physically Damaged or Swollen
A damaged or swollen lithium-ion battery should not be ignored.
Look for:
- Bulging laptop bottom cover
- Raised touchpad
- Laptop not sitting flat
- Visible battery swelling
- Unusual smell
- Physical damage to the battery
If the battery is swollen:
Stop using the laptop and replace the battery safely.
Do not puncture, crush, bend, or attempt to repair a swollen lithium-ion battery.
How to Know Whether the Battery or Charger Is Faulty
A simple symptom comparison can help identify the likely cause.
| Symptom | Possible Cause |
|---|---|
| Laptop shuts down immediately when unplugged | Battery severely degraded |
| Battery stays at 0% | Battery or charging problem |
| Battery percentage never increases | Battery, charger, or charging circuit |
| Laptop does not detect the battery | Battery connector or battery electronics |
| Charger becomes very hot | Possible charger issue |
| Laptop works normally but battery runtime is very short | Battery degradation |
| Laptop does not charge with multiple compatible chargers | Possible charging circuit or battery issue |
This table is useful as an initial guide, but proper diagnosis may be required for an accurate conclusion.
