Dell 3537 i on my laptop but display doesn't show anything but 4 white lights are turn on what is the problem pls fix it s

Try this...

  1. Turn the laptop off (not sleep or hibernate but off).
  2. Connect an external monitor to the laptop.
  3. Turn on the external monitor.
  4. Turn on the laptop.
NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

You may also want to try hitting CTRL + SHIFT + WIN + B to try and reset your graphics driver as another possible fix.

Pls tell me the solution for that problem sir
If the status lights turn on and then stay on, that is an issue with the motherboard. You can try to reset it by removing the battery and the CMOS battery from the motherboard if there is one, then hold in the power button for about 30 seconds. Plug in wall power only and see if it turns on. If it does, plug the batteries back in and see if it works after that.
