    Hi  VivekSingh1999,

    You can do a power drain test and load bios defaults on your computer.   Most of the times power drain test and bios defaults will fix the issue.

    These are the basic steps that you need to follow.

    Power Drain test for laptop.

    If your computer is not having the inbuilt battery follow these steps.

    1.  Turn off the laptop.  Unplug all the cables and devices including power cable.

    2.  Remove the battery if it is not inbuilt.

    3.  Hold the power button for 50 seconds.

    4.  Connect all the cables back

    5.  Turn on the computer.

    Steps to remove the battery.

    1.  Turn off the computer.   Remove all the cables and devices including power cable

    2.  Turn the laptop upside down.  Flip the laptop.  On the back of laptop there will be a unlock switch.  You need to move the switch to the left or right and then you need to pull the battery door out.  

    If your computer is having an inbuilt battery follow these steps.

    Power Drain test.

    1.  Turn off the laptop.  Unplug all the cables and devices including power cable.

    Flip the laptop.  On the back of the laptop there will be a tiny hole.  It is called a battery reset hole.  There will be a battery symbol right next to the hole.

    2. You need to insert a paper clip or small pin gently inside the hole and hold it for    30 seconds. 

    3. Plug all the cables back and turn on the computer.

    Step 2

    Bios Defaults.

    1. Turn on the computer and keep on tapping f2.  It will go to bios setup utility

    2. Press f9 once on the bios setup screen.   It will show you bios defaults.  Please press yes.

    3. Press f10 on the bios setup screen.  It will show you "yes" to save the changes.  Please press yes.

    Computer will automatically restart and it will load windows..

    hello,
    i have been googling but please could someone explain to me - as if you were explaining to a five year old - what i need to do in this situation:
    my laptop froze up and died. when i turn it back on there’s just a large lock icon. pressing f2 gives nothing. It is asking to
    insert recovery media and hit any key
    then select boot manager..’
    pressing okay then takes me around in a circle as there are no options..
    what do i do? what is recovery media?
    how can i solve the problem?

    [My device: Aspire E 15]

    I barely need the laptop. Please help me
