Re: laptop wont turn on

Are there any noises like its attempting to start up? Any beeping, fans running? If there are and the activitity lights are flashing, but just the monitor is off, than I would definatly say there is probably a bad connection between the motherboard, and monitor.

Acer Aspire One D255-2256 will boot and shut down but when shut off screen turns white until I unplug AC Adapter. I can power back up and boots but when shut down as long as AC adapter is plugged in screen...

Graphics chip may have failed. If screen is white there is no information being sent to the screen, but the backlight is working fine. The Graphics chip may not be replaced, but the motherboard replacement is the usual fix for this issue. There may also be a loose cable beneath the case above the keyboard, which connects the screen to the motherboard.

Easynote tj74 wont turn on

Your not getting power? When you plug the laptop in does the Battery charge light come on? Are you getting power to the laptop? Do you have a multimeter to verify voltage from th AC outlet to the AC jack? Or ,the power gets to the laptop and push the on/off button you get no response? Or, you push the on/off button and the laptop starts then shut down? No lights, no leds blink. Remove battery, Try another cord/charger. Has it been dropped or damaged that would jar loose a connection, or pulled by the cord resulting in a damaged AC jack?

I have a problem with my sony vaio!it seems to crush when i move the charger!its not shutting down but the scen is off and then i have to remove the charger so it shuts down and turn it on again!plus it...

It sounds like a loose connection in the charger cord or the AC jack. If the laptop is pulled by the cord it could have loosened/damaged the AC jack. If you remove the battery and only use the AC cord does the problem change? if you only use the battery and no AC cord does that change the problem? When Power is removed, without a proper shut down, the machine sees it as a crash therefore the disk check and black screen with boot options.

The back light is out, how to turn it on?

1.Check your monitor brightness setting. Occasionally, the monitor brightness can get accidentally turned all the way down. This will result in a completely dark laptop screen that appears to lack a backlight. Adjust the monitor brightness via the dedicated brightness keys at the very top of your laptop's keyboard.

2.Toggle the backlight back on via the keyboard. This is accomplished by using the "Function" key, which lies near the bottom left of your laptop keyboard and is marked "Fn." When pressed in conjunction with one of the "Fx" keys on the top row of your keyboard, you can toggle the backlight on and off automatically. There is an "F1" key, an "F2", and so on. The exact key to press simultaneously with your "Fn" key will vary by laptop model, so consult your computer's user manual. You may have accidentally toggled the backlight off and simply need to toggle it back on via this key function.

3.Prepare to operate on your laptop if you cannot toggle the backlight back on. Shut down the laptop. Disconnect the AC adapter cord from the back of the computer, then close the display and turn over the computer.

4.Remove the battery. The battery on most computers is at the top of the laptop's underside, although some computers may feature the battery in a bottom corner. The horizontal outline of the battery will be clearly visible all the same. Beside or just beneath the battery will be a battery-release latch. Slide this to disengage the battery.

5.Turn the laptop back over. Open the display.

6.Observe the bezel, which is the perimeter that runs around the display. There will be a number of rubber caps that exist on the bezel. The exact number will vary by laptop model. Use the tip of a flat-head screwdriver to pry under the caps and pop them off.

7.Remove the screws under the laptop bezel's caps with your Phillips screwdriver.

8.Work around the bezel's perimeter with your fingers and pry the bezel completely off.

9.Look at the bottom of the monitor assembly. A thin inverter board will span horizontally across the screen's bottom. There is a connector on either end of the inverter board. If the right cable is loose from the right connector, lift up on the connector and slide the cable back in. This will restore the laptop's backlight.

10.Replace the bezel and the bezel's screws. Reinsert the battery and power on the laptop.

Just got cq56-115dx laptop this morning. turned it off after setting it up. Turned it back on and only have blank screen. Power shows lit up.


Remove the AC power (charger) and then take the battery out. Plug in just the AC power supply and turn the laptop on, see if it boots up and shows a display on-screen. If it boots let it boot up and then shut it down as normal. Reinsert the battery and try as normal.
If you still get a blank screen can you then tell me if you get any post (splash) information like the Compaq Presario logo before it goes blank.

Good luck.

I have dell c840. Suddenly only the left most light of the three lights gets orange when power is switched on and then there is no activity and screen remains blank. Bty light when plugged in also remain...


shut down computer - unplug power cord from laptop - remove the battery from laptop - plug Ac adapter into computer and Ac outlet (wall)
turn on computer
if computer does not turn on, replace the AC adapter and cord - then place battery back into computer
plug in new Ac adapter and cord - recharge battery - if orange light stays on after 4-6 hours of charging battery, you need new battery as well - replace battery, charge it up and it should be fine

if you have attempted these steps before and no change occurs, then you may have issue with power connection in computer - locate a service centre to replace power connection on computer

I have a toshiba satellite laptop the screen is black

Shutting the computer down could be done by holding the Power Switch down for 10 seconds, rather than unplug/no battery "solution". A blank screen is more often than not caused by the failure of the screen's backlight. Plugging an external monitor in the ext monitor port would verify the computer still works, and I am sure it does.

Screen wont turn on

remove the battery and the power from the laptop.....then press and hold down the power button for 20 seconds ...... attach the AC power only and turn on the laptop this should turn on the system.
This drains the capacitors on the system (safety feature of laptops ... quite common)

If this does not work remove the Ram and reseat it ... something has either come loose or the backlight on the LCD has gone bad.

The lid actuator switch may not be working correctly. It's a small switch above the keyboard and led's on either the right or left side. Try pressing it 2 or 3 times to see if the display starts working correctly again. If so, it will need to be replaced.

If that doesn't work, you can also turn it on with the ac adapter plugged in. After it boots, press the power button and hold it in until it shuts off and then turn it on again and see if the display has returned to normal.

If neither of these options work, your laptop may need to have the backlight replaced.
