Monitor No Signal or Going to Sleep When Connected To Laptop?

My laptop is Asus u45jc-a1


i3 m370 @ 2.4 ghz processor

4gb ram but i recently upgraded it to 8gb ram

250gb ssd samsung


Last year i bought a monitor that is hp la2405x because it has 1920x1200 resolution which i need because i need it to play online poker. I would connect my laptop to the monitor by vga cable. I noticed that the monitor would keep on going to sleep. Example i would be on the computer for few hours or play poker for few hours, then this message would show up. Then my HP monitor screen gets the no signal and then go to sleep and when im playing, i have to wait like 1 minute or so, then hold the power button on my laptop for a few seconds then it turns off. The i press it immediately and then it would show resuming windows. This was the fastest way for me to get back on the tables when not sitting out longer.


However if i dont wait 1 minute or so and then i just press/hold the power button immediately, then i would shut down my laptop which is horrible because if im playing tables, then i have to wait a few minutes due to having to power up the laptop again.


I then wondered if this was my monitor or it could be my laptop as i read it has something to do with video card? Well what happened was later on, i didn't seem to have this issue anymore then after a while it came back again. This is very annoying when playing on pokerstars due to you going to miss out few minutes if you close the computer while playing because you going to be sitting out etc.


I then later on tried my laptop on another monitor a dell one. Note this monitor is very old, like 8 years at least. Similarly it had the same issue. It would go to sleep just like the HP one which when i bought it was brand new. The thing is you never know when its coming, it might happen once a day, twice a day, or 3 times, sometimes none. Im currently using another monitor and i had this issue yet again. This monitors an Acer. However, it doesn't say go to sleep like the HP one. All it does is have the no signal message. All of these monitors i connect to my asus laptop by the vga cable.

 

Does this mean this is 100 percent my laptops fault then? Does anyone know what i can do to fix this issue? Does anyone know why is it that if you wait 40 seconds then press/hold the power button, after few seconds it turns off then you press it again, then it shows RESUMING WINDOWS but if you do this too quickly after the no signal, then press/hold the power button basically turns off the computer, then powering it on again makes you start windows as oppose to resuming windows which takes much more time?


Its very annoying when playing poker and many tables and this happens b/c im going to be sitting out tables due to this.


Another thing i notice is let say im on the computer most of the day but not playing poker, the monitor would go out once a day maybe or not at all. However when im playing poker all day, it will happen at least 1 time a day, sometimes 2 or 3 etc. Rarely does it never have the no signal.


Of course when im on the laptop only and dont connect it to any monitor, i never have this issue.


Does this mean its my laptop and probably the overheating or using too much electricity on the computer? The vga is plugged to my laptop so it isn't loose. Im really confused at this and i basically cannot play poker if this happens as there is going to be at least 2 minutes downtime each time it happens.

 

Drew01, in Windows power settings set Turn monitor off after to Never (0).

 

Yes i did that already.

I did try to update the video driver. But each time i did this and restarted the computer, it would have the black screen and it doesn't do anything. Then i have to system repair and system restore each time then it goes back to where the updated driver didn't install.

 

Could it because of overheating or too much dust inside the fan of the computer? One person suggested this but said i would need to open up laptop which i dont know how to do.


The other person said he had simlar issue with monitor and his computer and said updating driver solved this issue with the no signal in monitor.


However, could it because the driver im installing is not good? Such as install a driver but not the most up to date one? I did read online that geforce 310m seems to have similar issues with other ppl such as black screen after installing driver and then restarting laptop.

 

Could it because of a bios update? Read a thread about someone mentioning their asus laptop had this problem and updating the bios in it fixed it. However few others said that doesnt work.


If so how does one do a bios update for asus laptop?

 

Someone posted this on forum.


Dear all,

I have found a solution to most of your problems.

Simptons: Black screen after installing Nvidia Graphics Drivers

Solution: If your motherboard has an onboard graphics card, disable the onboard and set it to boot from PCI Express slot 1 (if you have it in slot 1, if not so then set it to boot from whatever slot you have put your graphics card in). Once done so, restart and it should go to the graphics card and boot up as normal.

(These problems mainly occur on the GIGABYTE boards with the UEFI BIOS

Problem: Certain motherboards (mainly intel type boards) fail to disable the onboard graphics when PCI graphics is installed.



Does this require you to open up the computer?

 

FYI this is a laptop not a Desktop two totally different hardware...double check that your help is related to laptop and not desktop? So let's stick to the laptop help not inject a Desktop help that can't be done on laptop.
