What could be the problem with my Gateway NV59 not turning on. I have it plugged in in case there is a problem with the battery but still no power

Open the case to see it you and a green light on your motherboard if you do. Look for battery in the computer and pull it out with the power plug unplugged. Plug-in and power on with the battery out power the computer

Hello there

Those sneaky drivers, you can reinstall them when going to control panel, and look in the device manager. if you see and exclamation sigh yellow, you can delete and do a refresh again, or restart the computer if need the CD from windows, now is the time to install the driver. or go to gateway page and select drivers, with your model . that will do the trick.

Have you tried a factory restore?

You may want to try this link as it is still common for Microsoft to circumvent the problem rather than fix it !!!! Hope this helps.

I have two of the Gateway units and both do and did beep if on and power cord inserted---normal.

If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp. Please click on this link and follow myinstructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

If this is the case, i hope there is a problem in the power supply section. Go to the service center, & replace the Power supply of the laptop & try.

Method.

When your Gateway computer is switched off, it still keeps track of various system information such as the date and time, thanks to a small battery that never powers off. The size and thickness of a dime, the CMOS battery can run out and need to be replaced. You can swap out a dead CMOS battery with a new one by removing the Gateway computer's side access panel.

Difficulty: Moderate
Instructions Things You'll Need:

• Phillips-head screwdriver
  

• CMOS battery replacement
  

1. 1
   

   Shut down the computer. Remove the power cable from the back of the computer case. Disconnect the cables for the monitor, mouse, keyboard, and printer.
   

2. 2
   

   Set the computer case over on its side. Use the Phillips-head screwdriver to remove the two case screws at the far left end of the case.
   

3. 3
   

   Slide the side access panel to the left and remove it from the computer case. Find the CMOS battery port, which will be located to the lower left of the processor in most Gateway computer models.
   

4. 4
   

   Lift up the plastic clip holding the CMOS battery in place. Slide a fingernail under one side of the battery and lift it off the motherboard port.
   

5. 5
   

   Check the orientation of the new battery and compare it to the CMOS motherboard port. Push the new battery into place in the same direction that the old battery was facing. Push down the plastic clip.
   

6. 6
   

   Set the side access panel back onto the Gateway computer case and reattach the case screws. Plug in the Gateway computer and power it on.
