compaq presario cq57 wont turn on

[Help-needed]

A few months ago I purchased a compaq presario cq57. About a week ago it started showing a screen during start up saying for compatible battery preformance please replace current critically low battery. I left it on the charger about 14 hours a day to ensure it wont overheat and while charging it was off. Now the computer wont turn on at all also it will not charge.

Sometimes electrical components needs to have all power sources removed and reintroduced to work properly.  Try performing a hard reset first, if it doesn't work then we'll move to the next step.

To Perform A Hard Reset

• Shut down the computer by going to the Start menu and selecting shut down. (If you have no display, hold the power button down for  5 seconds); (if the computer doesn't power on, move to the next step)
• Disconnect the AC Adapter from the notebook.
• Remove the battery from the bottom of the notebook.  There will be a switch/button to eject the battery.
• Wait at least 1 minute with all power sources disconnected.
• Re-insert the battery and reconnect the AC Adapter and then attempt to power on the notebook.
