Acer 4320 Screen turn blank when it load Windows.

How to fix or troubleshoot blank or black screen not powering up issues...

Hi Jim,

this seems like a no boot / no video kind off issue and mostly is coz of corruptions in softwares or drivers, try booting the computer in safe mode. if it does, then take a data backup. i would not recommend experimenting in this issue as it can crash the computer.
hence call 1-877-805-1027 for expert help.

The problem is most likely the DC jack in the laptop, causes are no power to intermittent operation, but if the screen blacks out it means the LCD display has issues especially if the rest of the laptop is working, could be a loose video cord from the screen to the motherboard has come loose.

ACER Aspire 4730z laptop wont load into Windows

Hello Karthik,
This must surely be a problem with your monitor, because you say that you see the white screen while boot up. If this is a graphic driver issue, you may have the problem after booting up in windows. Since its been only a month old laptop, the product must be in warranty for sure. Take away any CDs in the drive, any USB drives and see if this white screen appears. Let us know.

Thank you!

Hi,

first try booting the laptop and pressing the Fn key with the numerical ( numbered key ) that has a picture of 2 screens on it. This is for booting to an external monitor. you could also try adding an external ( pc monitor ) this will eliminate any motherboard Faults.

Secondly, the graphics chip driver may be corrupt or not installed correctly. if you have a restore cd, you could try booting the laptop, with the cd in the drive.

you can then try, to see if the settings in the bios are all correct, by booting/starting the laptop and pressing esc or F2 or delete immediately as the laptop starts. ** Be-Careful** what you adjust.
My suggestion is to look for. ** default settings tab** or load setup defaults.

these are the obvious things to try, before assuming that you have a faulty graphics chip or motherboard fault.

There should be a display toggle key on your keyboard. This will toggle the display from the external display to the laptop lcd. Try pressing the Fn + F5 key to toggle the display.

Before bying parts hold down the "Fn" key and hold down the up arrow - this usually increases screen brightness
