Does not turn on


Hello

With any monitor, check the following to determine if the issue is MONITOR related or COMPUTER related.

1. Verify the monitor is receiving power - use a known good power outlet and plug it into the monitor

2. Samsung monitors have a light on the power button - are you getting any color light from this? Orange means it is in "stand by" mode and is waiting for the PC to send it a signal. Green means the monitor is getting a signal from the PC and the monitor is on.

3. With the monitor on, press the buttons on the monitor to bring up the OSD (on screen display) that changes the monitor settings. If you have a green light on the power button and press one of these buttons (AUTO works best), this will display the monitor adjustment options on the screen.

If you see the on screen adjustments, your monitor is working and the issue may be with your PC. Move the monitor to another PC and verify the monitor is working correctly.

IF you don't see anything on the screen and the power light is green, the monitor has failed.

This could be the lights that illuminate the screen have failed (something that happened to my Samsung Syncmaster monitors after about 6 years of use) or the screen has stopped functioning. In either case, replacement parts are hard to find and a monitor swap is likely.

My screen is black


When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.If it seems like the laptop is up and running but the screen is not displaying anything then the issue is with the screen. Take a flashlight and shine it on the screen and look very hard and you might see the icons or something very faintly on the screen. If so, your LCD Inverter needs to be replaced. It is located at the bottom of the screen and covered by the strip that goes around the screen. IIf you don't see anything on the screen then try plugging an external monitor to the laptop. I can be any kind of monitor, even the old big fat crt's as long as it has a vga cable that can go into your laptop's vga port. If you see the image on the external monitor, that means your video card is good and the screen needs to be replaced. Sometimes you might have to hit the FN key plus one of the F1 thru F12 keys to get the image to display. The correct F1 thru F12 key will either say CRT/LCD or it will have the icon of a display on it. Press and Hold the FN key then hit the correct F1 thru F12 key. This will toggle the the image to display either on the computer's screen, the external monitor screen, or on both screens.

Shut down my Acer 2480 wrong by pressing the power button. Now it doesn't reboot or boot up. I tried to pressing F2 to reboot but it doesn't do anything. Any suggestions?


Look at the power indicator:
If it is not lit, no power is being supplied to the computer. If the computer has a battery, it may be low and unable to power the computer. Connect the AC adapter to recharge the battey pack and make sure the AC adapter is properly plugged into the computer and to the AC power outlet.
If the power indicator is lit, check if a non-bootable (non-system) disk or USB thumbdrive is in the computer. If so, remove it and press Ctrl + Alt + Del to restart the system.

Pressing F2 by itself is only used to enter the system's BIOS on startup. If the power indicator is lit but nothing appears on the screen - The computer's power management system automatically blanks the screen to save power. Press any key to turn the display on.
If pressing any key does not turn the display back on, check the following....
1. The brightness level might be too low. Press Fn and the right cursor key to increase brightness level
2. Display device might be set to an external monitor. Press Fn and F5 to toggle to the internal display
3. Backlight might be turned off. Press Fn and F6 to turn on the backlight.
4. If the Sleep indicator is lit, the computer is in Sleep mode. Press & release power button to resume.

My Dell laptop just froze up and died. Won't reboot or start up. Is it a battery problem or something else?


hi,first you can do a power drain where you have to take the battery out and then press and hold the power button for 2 minutes without the battery.put the battery back after 2 minutes and see if it can turn on if the problem still persists then see if you are atleast able to see the power button light and other lights are glowing if yes and still you dont see anything on the screen then it might be either a video card issue or display issue to check connect a external monitor on to the VGA port and press and hold Fn KEY and press F8 once and see if you are able to see anything on the external screen if yes then display issue if no then video card issue.
now to isolate the problem turn of the system and press and hold the Fn KEY AND THEN press power buton both at the same time untill you see anything on the screen it will start a diagnostic on the system and also give a error code with description of the cause

Hi ive got a dell studio laptop the laptop powers up but nothing comes on the screen. The screen is less than 12 months old


HI there.
Try this things first so that you can check if it is really the screen that's causing the problem,
While the computer is off, press D+POWER button and hold it for 5 secs, different colors should come up,
Make sure the computer turns on. You will know that if the power button lights up. Try to lug in an external monitor and see if display will come up,
If the display comes up, and the d+power did not display anything, might want to call technical support so you can get the screen replaced,
Have a good day!

Laptop won't boot (display problems)


If the diagnostics displays on the LCD screen but you get no display when Windows starts to load, it sounds like you have a video software driver problem. Try tapping the F8 key when you power on your laptop and boot in Safe mode. If it works in safe mode then you need to check you driver. You can also try connecting the laptop to an eternal monitor and see what happens.
