Rosie, just some preliminaries
More info - what if any, is the complete error message?
How old is the machine?
Exact model number?
Has new software or a driver been recently installed?
Is the laptop used by you or others where you might not know what they do?
Malware vs incompatible software vs hardware failure.
The error message that your battery has experienced permanent failure might
not be a message about the laptop battery, it might be a small battery inside
your laptop called a CMOS battery. The request to select F2 to enter setup
is sometimes known to be CMOS battery failure.
Flip the laptop upside down take out the dead laptop battery that your
recharge cable is supposed to charge. You will be looking at a rectangular flap
with a spring loaded slider button, maybe two of them, to simply slide and the
battery will pop out. Remove the charging cord and then press down on the startup
button as if you were starting and keep it held down for 30 seconds.
Of course it will not start but you will be resetting some things.
Insert bad battery and plug it into the wall again.
See if it will start in safe mode:
Before you touch the start button, start pressing the F8 button up and down consistently
at about 2 clicks per second, as you keep doing this turn on the machine. If you have been
consistent with 2 clicks per second and started this clicking *before* you tried to fire up
the laptop you might enter a black screen with various "Safe Modes" that you must choose with
the keyboard's up and down arrows. Try Safe mode with networking, select it with your arrow keys
and press enter. If you get in, check your time and date and set it. Restart the laptop and see
if the date and time is still correct, if not the CMOS battery is very likely failing.
Malware - Incompatible software.
If you can get into safe mode and understand system restore, restore it back to a previous
time where you know it worked. To access System Restore open the Start Menu and the cursor will
be automatically blinking waiting for you to type. Type: restore
then you will see: 'Restore system files and settings from a restore point'
Either choose: Recommended restore (or) Choose a different restore point
I would choose a different restore point and you can select any point depending on date.
You can select: Show more restore points.
Hope this helps
