Restart your computer and then press and hold F8 keys until you get Advanced Options menu screen.Use the arrow key to highlight Safe Mode, and then press Enter, your computer will boot automatically to safe mode.
If you able to start in the safe mode then Scan your computer for viruses. Some viruses can cause a black Screen , especially ones that infect the master boot record (MBR) or boot sector.
Update drivers for your hardware. black Screens are hardware or driver related so updated drivers could fix the cause of the STOP error.
Return BIOS settings to their default levels. An overclocked or misconfigured BIOS can cause all sorts of random issues, including black screen.
If it doesn't helps you then simply get the system utility program like PC Fresher that will fix windows errors that cause of black screen screen

Display flickering


It could be a loose connection from the LCD screen to the motherboard. However, this can be risky to fix unless you are experienced with laptop repair.

It could also be faulty graphics card.

Graphics drivers may need updating.

The screen itself could be faulty and failing.

The system power supply may be faulty and not providing enough power.

Basically, it needs service - probably by a certified Dell technician.

Hi,

Welcome to FixYa!


It seems that you are having problem with the LCD or the display on the laptop, you just said that its tyrning on but there is no display appearing on the screen. This may cause by an electrical charge in the motherboard itself,Im not really sure how it affects the display of the computer.There's also a possibility that the problem is with the LCD cable or the LCD itself. Please follow this method since it usually fix such problem like that,

1.Removed the battery then unplugged the AC adapter

2.Press and hold the power button or the ON/OFF button for at least 30 seconds

3.Connect the power supply back to your computer then turn it back on.

4. Check if you will see any difference.

5. If nothing happens, try to press and hold Fn and F2 on the keyboard.

If nothing happens, there is a possibility that the problem is with the LCD or monitor itself, maybe it will need a replacement...

Hope this information will help. Thank you for using FixYa!

My lenovo 3000 G410 when ia tr to start it nothing happens???? help


Hi,

Is there power when you turn the system On?

In your case it is very difficult to find out which is causing the system not to power, this can be multiple devices on your ssytem.

trying to eliminate one device after another try following the steps below:

>remove the Battery from the system, unhook the adaptor as well then Press and Hold down the power button for 7-10 seconds to drain any power on your motherboard.

>after power draining the system connect the adaptor to your laptop, do not insert the battery yet, Power the system without the battery, if the system turns on leave it turned on for about a minute then shut it down normally.

>insert the battery to the laptop turn the system on if this turns on without any error then your concern is probably ok and fixed.

>but if the system still does not power up having the battery connected to the machine a device on your system can or maybe damaged either the Battery or the Motherboard having an issue with the battery conencted to the machine...

if your system is in warranty call Lenovo and have it sent to teh service center for proper checking and repairs.

Cannot tune to local stations


- The 0.2MHz odd steps are standard for US radios. Try resetting the radio (recessed button under the front panel) If this a US radio then this may not help. If you have lost the manual then go here:- http://books.jvcservice.com/booklist.asp?Model=KD-G400 Come back and say if this helped or not, I could dig a bit deeper.. -
