My laptop when I turn on the power it appear a hp screen and then it turn black and it appear a dash blinking fast and after that the keyboard cant function when I press any button.

Try this on an external computer monitor. If it works ok there, the inverter on the screen of the laptop is failing and needs replacing, or the screen backlight may also be going ( new screen needed)
If it does not work on an extyernal monitor, its the usual HP problem of a graphics chip unsoldering itself. You will need a new motherboard or a reball carried out.

You can also check that you can hear the fan working, if it is not, and the laptop is getting hot, or if the fan is always on, you have an overheating problem, a dead cpu fan or connector. This will necessitate opening up the laptop and inspecting the fan / cleaning the heatsink.

Is my laptop overheating? It will work for a bit then get a black screen w/ lines through it.

Hello Kenny,

You laptop likely is not overheating per se, but it appears that the cable located between the video card part of the motherboard and the monitor may not be secured as it should. Vibration, and perhaps temperature, can cause this cable to shift ever so slightly causing symptoms that you describe.

If taken to a repair shop, the charge should be nominal for them to disassemble the laptop to the point where they can access and secure the cable. At worst, the cable may need to be replaced due to wear.

The easiest way to confirm that it is a cable or not is to try and plug in a monitor to the back of your laptop. If the problem appears on the panel, and not the external monitor, then you are almost certainly looking at a cable issue. If the problem appears on both monitors, then it is a different issue, perhaps overheating like you suggested.

My laptop is not working. When I press power button, only blank screen appears. But the processors' fan is functioning

Hi. I would suggest to power drain or power cycling your laptop, by removing the battery and unpluging the ac adapter and press and hold the power button for 20 sec while the battery and ac is out then plug it all back then turn on your computer. If this dosnt work try reseating the RAMS or memory of your laptop. If does Troubleshooting step doesnt fix your issue then maybe this one is already a LCD hardware issue. Also try calling there tech support hotline at 800-426-7378 if your laptop still under warranty and they would replace the LCD without any charge. Hope this Helps.

For that first open cpu cabinet then reattach the RAM memory.
Pull cmos cell from motherboard for 10 minutes.

My computer will power up, I can hear the fan working etc, all things are a go and there is even sound when I hit butons etc. it appears to be working but my screen is black

Plug in an external monitor to your laptop, if you see an image on the external monitor then your laptop screen is bad. It could be the screen itself or a video inverter.

If you can't see an image on the external monitor, then your video card on the laptop may be damaged.

Good luck

I turn on the actuall computer but it does not work i try the keyboard notheing it try the mouse notheing and the montitor does not turn on eithrer

Do any / all of the fans work??

If power supply fan doesn't work then most likely faulty power supply. (Try borrowing one to test)

If it still doesnt work then may be faulty mobo, CPU, ram stick.

If you have to purchase another power supply ensure its a higher wattage than the one fitted. Makes your PC a little faster!!

My emachine T1742 desktop will not turn on. When plugged in the power supply's fan turns on, cpu fan doesnt start, both hdd/power led's flicker and pressing power button doesnt power on/off system.

Disconnect all the devices from the computer(tower) including keyboard, mouse, monitor(everything)..even the power cable

Now keep on holding down the power button on the computer tower for 15-30 seconds..

Now release the power button, plug in the power cable, monitor, keyboard, mouse and turn on the computer...

If it works, great!!!

Otherwise, take it for repair..

Booting Failure

Try removing the HD, then boot. If this doesnt work, then try the RAM, wireless card, and any other device. If this doesnt work, then it is something to do with the motherboard or LCD monitor.

Hook the lapto up to a VGA monitor. If it shows video then your LCD screen is toast, or one of the connections. If no video comes out at all, then your mobo is probably gone and you need to replace it.
