|Does the computer show lights that it is coming on or do none of the power lights come on at all? Have you accidentally dropped the computer?|
1) You my have not put the battery in properly:
carefully disconnect the battery and look to make sure that it is not damaged on the area which it uses to connect to your computer and also check the laptop and make sure that the connector is not bent or damaged.
Then reinstall it, go ahead and snap it into place, making sure that everything is sealed and in alignment.
after that, make sure that your battery light is lighting up on the laptop and showing that it is connected/charging.
(Some battery lights will show an amber or orange light, meaning that it is fully depleted. If it blinks blue/amber then the battery is too hot to charge and most be disconnected from the wall and put into a cool place.)
Now see if the computer turns on.
*If it is still not powering on*
2) The battery may not be proper temperature, some batteries wont turn on if it is below 0 degrees Celsius(32 degrees Fahrenheit)
3)Test the electrical outlet that you are using.
4)Check the AC adapter connection, and if there is a light for it make sure that it is on.
5)Stop using a power strip or extension cable and just connect it directly to the wall.
6)something may be interfering with it, so make sure it is not next to other electrical devices.
- As a last resort, if nothing else works you may need to do other things but let me know how that works first.
