Laptop Suddenly Shuts down after turning and videos flicker white sometimes

2020-09-21, 3:46 AM

So my laptop when I turn it off and turn it back on the battery says a decent percentage, but then would suddenly shut down and after I put the charger and start it again it showed that it was drained at 1 %  . In addition, especially when I play videos the screen would flicker white sometimes.

Hi there SereenYoga920,

 

Welcome to the Community Forums

 

Here are some troubleshooting steps you can perform to try and home in on the problem:

 

Step 1. Generate a Battery Report:

- Follow the steps below in order to generate a Battery Report in Windows 10:

- Right-click the Windows Icon in the bottom left corner and select "Search"

- Type "cmd" into the search bar, right click the program showing up and select "Run as Administrator"

-----

- Copy and paste "powercfg /batteryreport /output "C:\battery_report.html" into the command prompt window. Without the quotations.

- Using Explorer navigate to C:\ aka the root directory. You should see a file labeled battery_report.html.  

Check here on how to read it. If you are unable to perform this task, then just continue below:

 

Please also run a diagnostic scan of the battery on the support site for your device.

Click Custom Scan and tick the box next to the battery.  

 

 

Step 2. What does the Power LED indicate ?

Lenovo laptops with a blinking battery light that is orange may indicate that the laptop is charging or that a battery error has occurred, depending on the speed of the blinking – or, in a different Lenovo model, a flashing battery light with a change of color merely signals that the battery is almost fully charged. 3 Blinks may indicate insufficient charge on the battery. If the battery light LED (which looks like a lightning bolt ) flashes, the battery has insufficient charge to start the computer.

In many cases, issues with AC adapters will be the result of temporary faults or shorts in power. In these cases, unplugging the AC adapter from your laptop and the electrical outlet, then either making sure all of its cables are securely attached or plugging it back in immediately can solve the issue and resume normal charging. Issues with batteries can often be solved by powering down the laptop, removing, then plugging the battery back in, or by performing a battery reset by letting the battery drain, removing it and then holding your laptop's power button for 30-60 seconds before charging it again. In the worst-case scenario where a battery or adapter has failed entirely, replacing your laptop's problem component will solve the issue.

 

 

Step 3. Static Discharge

**Note : If problems charging the device at all, try the other steps first, then static discharge if unsuccessful)

- Remove all cables attached to the device (power, hdmi, external mouse/keyboard, etc)

- Ensure device is switched OFF

- Hold down power button for 60 seconds

- Re-attach all cables

- Connect the AC Adapter, then let the device charge for about 2 minutes (if it does) then start up as usual.

- If the battery now charges and/or there might be a sensor issue, continue below:

- Charge the battery to full, then perform a discharge of the battery again.  

- Do this 2-3 times to see if the sensor normalizes.

 

**NOTE

Step 4 and 5 are only necessary if you charge from USB/USB-C and have problems charging.  

Do note that you might be experiencing a sensor fault on the device, which Step 3 can help sort out.

 

Step 4. Checking The Advanced Power Options.  

- In the Search function type : Control Panel

- From the View By: select Large/Small Icons. Then Select "Power Options".

- Click "Edit Power Plan" for the plan of your device.

- Select "Change advanced power settings"

- Find and expand "USB Settings"

- Make sure the "USB selective suspend setting" is set to "disabled"

 

Step 5. Reinstall Battery drivers + Check USB Root Hubs and Generic USB hubs.

- Press Windows Key + X, select Device Manager

- Now click Batteries in the Device Manager window.

- Next, you should right-click Microsoft ACPI-Compliant Control Method Battery and select Uninstall from the context menu.

- Click Uninstall to confirm.

- While still in Device Manager, expand Universal Serial Bus Controllers.

- Right click and click properties on all USB Root Hubs and Generic USB hubs.

- Check Power Management, and make sure the computer is not allowed to turn these devices off to save power.

- Restart the device and have Windows install the generic driver type for this device.

 

Step 6. Updating the System Board drivers.

Make sure you have the newest BIOS, Chipset, Serial I.O, Management Engine Interface drivers and Power Management drivers for your device:  

You can find and install the newest drivers from the Lenovo Support Page

Just plot in the serial number for your device and hit enter, might have to hit it twice. Then head to Drivers & Software then the BIOS, Chipset and Power Management section.

**Note: Make sure the AC adapter is connected and that you have at least 30% battery charge when performing this update.

 

Regards
