There are two ways to discover the problem. The problem is either a software problem or a hardware problem. Since it's easier to discover a hardware problem, start there.

Did your laptop come with any kind of diagnostic software? I would run that first. The other thing you can do is to boot the system up and enter the system BIOS. Set the defaults, reboot the computer and see if the problem persists. If it does, you can reboot the system, press F8 several times, which will prevent Windows from starting and will give you a Start Up Menu. Press the down arrow key and choose Command Prompt. Leave the system running in this state and see if the problem occurs. If it does, it proves the problem is a hardware problem.

Running Diagnostics is the easiest and quickest route for discovering hardware issues.

Your laptop is getting HOT because the cooling fan may not be cooling the processor. All it takes is about 15 seconds to overheat the processor. Need to get it serviced.

Acer pc and lg monitor blank screen says power save mode on start up, anyone know how to fix this?


Actually during start-up there is a slight delay before the HDD & OS is detected by the CPU. Normally all monitors slip into power saving mode within 10 secs of inactivity of either mouse or keystroke. This inactivity is read by the monitor which promptly switches to power saving mode. However the moment the HDD LED starts blinking, the monitor wakes up & starts displaying. This power saving mode in most of the flat screens is only associated with movement of mouse or keypad. This does not register till the CPU starts up & thats why the monitor switches over to power saving mode till it starts receiving signal from the CPU.
It is a normal behaveour, so don't get worked up over it, plus you can always hit the Auto set feature on the monitor after booting the PC completely. ( I think the time out for the monitor to enter power saving mode is only 10 secs). Hope this helps.

My monitor goes blank while watching a movie on netflex about every 8 min very annoying . I jiggle the mouse and the picture comes back . sound ok . Help


Your computer is just going to sleep from what it sounds like.

Just get into the monitor/power saving/screen saver settings and make it so the monitor has a longer relay to shut down when there is no mouse/keyboard movement.

Hi,

Thanks for using FixYa!

You can isolate the issue by connecting your laptop to a monitor. If you don't see any picture from the monitor that you used, that means that your computer is not POSTing (Power on, Self Testing) You may need to bring it to the technician because they will need to diagnose the computer internals. I hope this helps.

Have a nice day.

When i shut my laptop the tv i use as my monitor goes blank.


Right click the power icon in the system tray (should look like a little plug with a lightning bolt on it.)  Click on "adjust power properties."  Click on the "advanced" tab, then where it says, "When I close the lid of my portable computer," select "Do Nothing."

Compaq 2100 Laptop Monitor KBD & Mousepad (Not working)


The monitor is defective and should be repalced. Keyboard and mouse pad problem could be a driver problem. Try to reinstall their drivers.
