Did you check the power supply? They go bad and if you get no power, nothing else will work. You can check the power supply by plugging the unit into an outlet and then using a volt-ohm meter measuring the voltage at the cylinder which normally plugs into the computer. If there is no voltage (DC) present, then the supply is bad. You can get a replacement online or at the place you purchased the unit.

Compaq presario V5000 laptop blank screen


Does the hard drive light blink like there is activity? It sounds like your laptop is not posting. Unfortunately on a laptop if it fails to post it is likely the motherboard..

I would verify first that you Cannot get the external monitor to work by using the function + Keys on your keyboard to enable the secondary display (Usually something like FN+F4) FN being the key on the lower left of your keyboard between ctrl and alt typically..

If you cannot get it to display, Try an ESD Discharge.. Basically unplug the power brick from the laptop, Remove the battery and try turning it on.. While trying to turn it on contact your fingers on the metal prongs that protrude from the where the battery was on the laptop. This will discharge any built up static electricity from the laptop. Try hooking it all back up and booting.. Good luck

- try to plug an external monitor on your laptop
- if you can see a screen on the external monitor, then you have a faulty LCD
- if you don't see anything on the external monitor, then you have a faulty motherboard

No screen activity


If you used an external monitor and got nothing on it, then the problem is the video card.

Baterry went off. i have charged it but the screen wont come on though i hear the fan. i have to remove the battrey to put it off. have tried an external monitor and it says computer on sleep mode. press...


Perhaps a result of the auto display off. press any key to activate the screen again.

If using the LCD screen, make sure the priority is not set on an external monitor. To do this, press the Fn function key combination to set the display priority.

if you use an external monitor:
1. Check whether the monitor is switched on

2. Check if the power cable is properly connected

3. Check if the cable menguhungkan external monitor and the notebook is connected correctly.

4. Try to set the constrast and brightness on the external monitor

Laptop screen blank at start up


If it still doesn't work when you hook it up to an external monitor, assuming you did that properly, then it is your motherboard/video card.

If you have a seperate video card, I would replace that first. If you don't have a seperate video card, then you need a new motherboard.

FIRST - I would try hooking it back up to an external monitor, and making sure you switch it over to use the external as the default. otherwise you wont get picture.

Sorry... good luck.

Monitor screen stays black even though it's on


Remove the memory from your unit - power it up it should beep if full communication is still happening across your m/board. No beeps you board has died. if it beeps and your using two diffent memory modules just fitt one leave the battery out and power it up = if no display pull power swap out the memory and try again. if display occurrs you have a defective memory module - throw that failed unit away

MX 6124 Gateway notebook screen stays black when powering up


Repaired! This sounde like a fuelty screen or screen inverter. To check this, connect to an external monitor, if the external works properly, then it's the screen or inverter. If the external doesn't work, let me know and we'll run the problem down to a more indepth (internal) trouble shoot.
