Re: the power light is on, but the monitor is off

Its the motherboard. If you laptop powers on for a few seconds then dies, it is the motherboard/systemboard.

HP 2000-410US when turned on the power light button blinks 1 time every 5 seconds, nothing elas

1. Disconnect anything that is connected to your laptop. Usb Flash discs, External HDDs, Wireless Devices using dongles etc.
2. Make sure that your device does not receive any power i.e. Disconnect your ac cable, and remove battery from your laptop.
3. Hold down the power button for 5 seconds. This would drain remaining power from your laptop. But as the power cable and the battery are disconnected, you should not expect anything to happen.
4. Identify where your RAM is located under your laptop. Unscrew the cover off, then remove the RAM from your laptop. Replace the cover temporarily.
5. Flip over your laptop. Connect your power cable to the laptop, NOT THE BATTERY NEH! Then press the power button. Sometimes your laptop will make long beeps to let you know the RAM is not inserted in your laptop. But nothing will happen on your monitor because it needs RAM to show you something.
6. After those beeps, remove the power cable. Press the Power Button to drain remaining power on your laptop. Flip the Laptop and replace the RAM you have removed earlier.
7. Insert your power cable and try restarting your laptop and see what happens. I am sure by now you should have some response on your laptop monitor.

NB: While performing the above mentioned, remember PC or Laptop parts are delicate. Even static electricity can damage them. Thus before handling your laptop components, make sure you touch the wall or any large metal subject from time to time to discharge the static. Wear 100% cotton cloths as you are working on it. Bare feet even better to discharge the static

My toshiba satellite m305 s4819 had a colored lines on the screen so I thought it was simple to fix so I open the screen and tried to open the inverter jack but it was small and hard to I used flat screw...

1) The FIRST thing you do when working on a computer, Desktop or Laptop, is to Remove Power.

2) The SECOND thing is to observe Anti-Static Precautions.

You need to disconnect the Video Cable, and the Inverter, FROM the motherboard.

This will ensure that the LCD screen, Backlight, and Inverter are taken out of the system.

You may have shorted across enough with the screwdriver, to just damage the electronic components on the Inverter.

With it connected in the system the computer will not turn on.

But I also want to take the Display Assembly, out of the 'equation' temporarily.

Of course the damage may be more extensive. Diagnose one step at a time.

Laptop off, monitor off; connect a VGA monitor to the VGA connector on the laptop.
Turn the monitor on, allow it to 'warm' up.

Turn the laptop on. If graphics do not automatically show up on the external monitor, press the Fn key, and hold it down, then tap the F5 key.

The F5 key is the toggle-over display key.
You can have;

1) Just the internal monitor of the laptop,
2) The internal monitor AND the external monitor,
3) Just the external monitor.

This is why you may have to tap three separate times.

No monitor/screen, but turned on. Light signifying the laptop is on - on green.

Try this:

1. Turn off the laptop by holding the power button in for 15 seconds or until the power light goes off.
2. Pull the battery out of the laptop and disconnect the power from it.
3. Hold the power button in for 20 seconds.
4. Plug the laptop back in, and put the batter back in it.
5. Now try to turn the laptop back on.

If this does not work, let me know.

Hello i have hp compaq nx9020 and when i press the power button the power led turn on for 2 or 3 seconds and then died again

With an extensive use of the notebook,
some times notebook would store some static charges which
indeed will stop the notebook from powering up or charging
the battery. The procedure to remove this static charges from
the notebook is known as power drain. Performing a power
drain procedure will not effect any personal data or delete
any pictures from the hard drive on your notebook.
I recommend you use Power Drain procedure by following these

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter.
5. Turn on the Notebook power.

When I turn on My HP Laptop the system start booting and all of the lights on the laptop turned on but the screen doesn't display a thing it is always dark could anybody help me... Thanks in advance...

This could be due to presence of static charges or hardware malfunction of video card or defective LCD display screen of your notebook. To isolate this issue, perform the following:


To perform a hard reset, please follow the steps listed below:

1. Unplug the AC adapter from the notebook PC and remove from any port replicator or docking station.
2. Remove the battery from the notebook battery compartment.
3. Press and hold down the power button for about 20 seconds.
4. Insert the battery and plug the AC adapter back into the notebook PC.
5. Press the power button to turn the notebook PC back on.

This will discharge the static charges from the notebook. Now check for the issue. If the issue persists then connect an external monitor to the notebook and check if it works fine. You can follow the steps listed below to connect an external monitor to the notebook.

1. Turn off the notebook.
2. Connect the monitor cable from the external monitor to the monitor port on the rear/side of the computer.
3. Connect the monitor to a power source and turn it on.
4. Press the Power button to turn on the computer.

At this time, please follow the instructions mentioned below for switching the display to the external monitor:

The notebook's video card supports three modes. Built-in screen only; external video only; and both on simultaneously (mirrored). If you're not seeing the image on the desired device(s), the notebook's video card is probably in another mode. Press FN + F4 to cycle through the display options: Notebook display, External monitor, both.

If you press FN + F4 once, the external monitor will display & there will be no Notebook LCD display.
If you press FN + F4 twice, the external monitor will display & there will be some shading on the Notebook LCD.
If you press FN + F4 thrice, both Notebook LCD & external monitor will display.

If the issue persists on the external monitor, then this could be due to defective video card on the notebook. However, if the display on the external monitor is fine, then the issue is with the LCD display panel of the notebook. In either cases, the notebook requires a detailed onsite diagnosis by a service technician.

Does not power on, but lights flash


Thank you for your query

The clicking noise you are hearing is one of 2 things

1) The CPU fan trying to turn but it cannot, therefore your PC comes on for a short period of time, overheats and switches off

2) The Hard drive is faulty and is causing a short, making the LAptop switch off

Either one will need further inspection by a qualified engineer

Please book laptop into a reputable PC shop for further diagnosis

If this has been useful please leave postive feedback/vote/testimonial - Thank You Again

Everex Stepnote NC1500 wont boot

Are there any other lights on or any other activity, or does it just die? If it only pops up with the hard drive light briefly then dies, your laptop might just be dying because the battery isn't holding a charge.

Eee pc won't turn on (I think have already posted this,not sure)

Sounds like a classic case of hardware failure!!!!!!! possibly your motherboard, start by removing the battery, hard drive and optical drive.
disconnect the laptop monitor and connect the laptop to an external monitor.
remove the memory modules clean the brass contacts with a eraser and place back in the machine 1 at a time to check to see if they work, remember to plug in the AC power suppy, if you see the post screen then its a memory issue and you can then reconnect your laptop monitor to see if it lights up, if everything works but the monitor then its the inverter or backlight that has blown and is easily repairable saving you money on a brand new screen
