Laptop broken screen... plugged in Dell monitor,still doesnt work


You can switch to an external monitor or data projector by two methods. 1. Connect the external monitor to the laptop's video port, power up the external monitor first and the laptop. The video information will automatically switch to the external monitor. 2. If you power up the laptop first then you can switch the video output to the external monitor by pressing the Fn key and one of the Function keys, depending upon your make and model laptop. You can also toggle between the external monitor or both LCD screen plus the external monitor or back to LCD screen only by pressing the Fn key plus one of the function key. Here is a list of key combinations for some of the laptops :- IBM ThinkPad = Fn + F7 HP and Compaq = Fn + F4 Toshiba = Fn + F5 Dell = Fn + F8

Windows won't start at bootup. Instead the fan turns on.


It sounds like your operating system has failed. Your best bet would be to use a working computer to burn a new install disc / backup disc / repair disc and then reinstall your operating system, or if possible repair it.
Have you tried plugging the VGA output into an external monitor and turning it on? Maybe your screen has just failed, if it does output to an external monitor.
You can get it into external mode if you boot it up with an external monitor connected, a USB mouse connected, and a USB keyboard. Boot up the machine (plugged in!) and close the lid right away, and it should automatically kick over. If not, try windows key and P at the same time, once the machine is "running"

Screen goes into standby mode after a few seconds. Screen will not stay on. Started after the computer was on and coming out of standby mode. Computer works fine on external monitor.


Depending on the options you purchased the laptop with, it either has an integrated video circuit into the motherboard or a plug-in video card to the motherboard. If the laptop works fine with external monitor, your motherboard or video card is defective. Your LCD display is probably O.K.

THE SCREEN IS DARK. tHE LOPTOP TURNS ON BUT HAS NO DISPLAY. IT WILL NOT WORK ON EXTERNAL DISPLAY.


Your video card is bad. A bad LCD or backlight lamp would not prevent an external monitor from working. Even without a hard drive or Windows installed you would still get a text display on your screen. Some laptops have replaceable video cards but some are soldered to the motherboard and can't be replaced. This is a job for a repair shop, not a DIY project.

No monitor n620c loptop


To switch between monitor modes (internal/external) you have to press the key combination Fn+F4 (or F8) or the F key with a dual monitor icon printed on it. This happens when you use the laptop with an external monitor or projector, and you forget to return to the internal monitor mode.

ACER cracked screen..external monitor???


Hi there.
The keyboard toggle you are using is the correct one.
Sometimes you have to hit Fn + F5 a couple of times to stay on there is no real set time. Make sure Fn + F6 is on so the laptop screen stays on.

Good luck and thanks for using FixYa!!

Powering


This is usually a sign of bad ram. remove the ram cover underneath, pull aside the pop out clips and remove the ram. hold the ram by its side and try not to touch the 'gold fingers'. Clean it / them with a soft clean paint brush along with their holders and re-insert. If this does not work and you have 2 sticks of ram then try each one on its own in one slot,then the other slot, turning on each time to identify the faulty module.
If this is no joy I would suspect the CPU. It could also be the motherboard video chip which is not repairable without a new motherboard but this is doubtful as it is not a common fault on this laptop.
Hope this helps some.
