Windows 10: My Lenovo laptop is misbehaving

It's been 2 months when my charger brokes so i have to find or replace it with another one. When I open my laptop, it seems to be okay. Not until, on the third day when I open it again I observed some problems:


1. It keeps on refreshing. 2. Whenever I inserted a wired mouse my touchpad doesn't work. 3. The F5 key doesn't work properly. 4. Whenever I set my laptop into sleep it awakens without clicking any key. 5. Any browser that I use keeps on refreshing. 6. When I open the ppt it keeps on slideshow without pressing F5 or pressing manually through mouse. 7. Same with ppt my word. F5 key keeps on functioning without manually clicking.



What should I do? I badly need my laptop because my online class is still on going.

I have laptop of Lenovo Z50 with 4 GB RAM

Initially after updating it to window 10 it was working properly but suddenly after some time it started misbehaving

every time I open my Laptop, it shows preparing windows on the screen and takes time to open the laptop

the most important thing is that its start menu is misbehaving

Start menu is not showing all the applications

if I make any change in my laptop then that change will automatically be changed to original one after I start my laptop again like if I change wallpaper of it then that wallpaper will be removed automatically after I start my laptop again

Fingerprint scaner does not work as expected in Lenovo laptop

Hi Robert,

What is the model of the Lenovo laptop wherein the fingerprint scanner does not work?

Since the issue involves working of the fingerprint scanner which came inbuilt with the Lenovo laptop, I would request you to contact the laptop manufacturer.

In the meanwhile you can execute the Hardware and devices troubleshooter and then check if it helps.

Windows 10 has a built-in troubleshooter to check and fix issues with hardware and devices. I would suggest you to run this troubleshooter to check if the issue is with the Bluetooth adapter. Refer these steps:

• 
  Press Windows key + X, select
  Control panel.
  
• 
  Change the view by option on the top right to
  Large icons.
  
• 
  Click on troubleshooting and click on the
  view all option on the left panel.
  
• 
  Run the Hardware and devices troubleshooter.
  
• 
  Restart your computer and check if the issue is resolved.
  

Please revert if you face any issues with the fingerprint scanner.
