Your are probably experiencing a short in your ac cable, the next time it happens wiggle the cable, if the ac pops up in the task bar stop using the charger and buy a replacement.
PS check the slot where the adapter plugs in the back of the laptop to see if its loose, if it is take to the repair shop.
compaq are known for tis problem.

I have a HP Compaq Pressario R3000 laptop that will not turn on. I recieved a message that the batter was low even though it was plugged in. I bought a new plug, still didn't turn on. Bought another...


This seems to be a common problem for this model. Some have reported a loose (or dry) solder connection on the mother board where the power socket is attached. Does it seem to work if you push the plug in harder, even for a second? . You should read this thread... http://www.tomshardware.com/forum/50946-2-compaq-presario-r3000-power-cord-issue It may not be your particular issue, but there is a likelyhood that it is. If you are not handy with delicate work, or a solder iron, I suggest a laptop repair shop. Maybe copy or print a part of the thread to clearly indicate what you want. Good luck

My compaq laptop powers up but the monitor stays black i tried to plug it in a monitor and nothing.


Unfortunately..your display may be shot...Is it a Compaq Presario? These laptops have a history of display problems...I have a Compaq Presario R3000 and the display is showing a reddish color in the left bottom corner of the screen and my brother had a similar problem with a Compaq laptop where the monitor stopped working....Unfortunately it would cost more to replace the monitor than to buy an Apple MacBook...
You can buy a cable and attach the laptop to a desktop monitor and it will work although you will lose the mobility of the laptop which is what makes a laptop so appealing.
If your laptop has a NVidia graphics card you can go to display in control panel and set it up to use Plug & Play Monitor but you may need to use safe mode or you wont be able to see anything because your screen doesn't work....You might get lucky and when you plug in the cable (just like you would to attach a PC tower to a monitor), it will work and you will be able to make the monitor the dominant screen.

I have compaq presario computer i want to know how to fix black screen i need help


Please just follow the below steps and fix up your problem

First take out your laptop battery then remove your Ac adapter cord,now hold down power button for 30 seconds.
That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen.
.
After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up.If not then you have to replace your battery.

Thanks.
Have a great day.

I have a compaq presario CQ61 it was working last night. When I turned it on just now I have a black screen but do have lights blinking on the key board by the caps lock and upper right.


Hi,

This is a notebook not a desktop computer.

Try this and let me know if it works.

Remove the AC power cord and the battery. Hold down the power button for 30 seconds to dispel any residual power from the laptop.
Then just plug in the AC power (leave the battery out) and try to boot the laptop up.

If it boots up let it load the operating system and then shut it down. Reinsert the battery and see if it will boot up.



Good luck.

Compaq presario sr1950 nx desktop - won't start


My suggestion would be to open the case and unplug everything and then plug it all back in again.
To test individual components, unplug everything but the CPU, memory, and video card to see if it starts.
Then one by one, plug the other stuff in and try starting again.

My screen stays black when you turn it on. model HSTNN-C17C which is located under the battery. Presario V5000


This isn't a desktop PC by the way. Do any of the lights come on? If not, try to run the laptop from the AC power. If the lights come on but no display, then your backlight or inverter on the LCD panel for your V5000 might be bad.
