Lenovo G530 laptop monitor randomly goes black

I have a lenovo g530 laptop since 2009.
At the time of purchase, the specs were:

1 gb ram

160 gb hdd

2..16 Ghz dual core cpu

Windows XP service pack 3

 

In April 2014, after the hard disk crashed, the system was upgraded to windows 7 service pack 1 and hard disk to 500 gb.
Last year, ram was upgraded to 2gb.

Since last week, I have been facing a certain problem.
At random times, the monitor suddenly goes black and everything else keeps working fine( I can hear audio in case I was playing videos etc).
 Playing with the function keys brings it back but the problem keeps on happening every day.
 Any idea why?

Hi Oolee,

 

Welcome to Lenovo Forums.

 

Did you try booting from safe mood? There is also a chances, if your cables are intact and not loose (VGA Cable), or the monitor loses power.

 

Please go through this HMM for hardware assistance.

 

Method 1:

Any external hardware can cause this (like a keyboard or mouse can cause system to sleep to save the power)
1. To change this go to “MANAGE” by right clicking on the “MY COMPUTER “ icon on the desktop .
2. Go to DEVICE MANAGER.
3. Click on the keyboard or mouse or any other USB devices and right click on them and go to PROPERTIES and select POWER MANAGEMENT and untick the appropriate box.

 

Method 2:

Control panel > Power options >Choose when to turn off the display (look for this in the side bar) 
Set “TURN OFF THE DISPLAY” to NEVER
Set “PUT THE COMPUTER TO SLEEP” to NEVER.
And then continue to “Change advanced power settings”
Go to "SLEEP"
Set "SLEEP AFTER" to NEVER.
Set “ALLOW HYBRID SLEEP” to OFF.
Set “HIBERNATE AFTER” to NEVER.
Go to “DISPLAY”
Set “TURN OFF DISPLAY AFTER “to NEVER.
Press APPLY and then OK.

 

Let us know how you get on.

Regards,

Shashi

For keyboard and mouse(both are usb devices of Logitech), I unticked the option "Allow this device to wake up the computer" which was ticked earlier.
Applied Method 2 as well.
Let's see what happens now.
