T6420 E-Machine won't/Reboot W/O F8 Key

My daughter’s T6420 E-Machine stopped working properly. The PC, during Shut-Down immediately displayed “NO SYNC” on the monitor and sat there with the Power light indicator still on. It would shut down after holding the power button for a few seconds.

During start-up and/or re-start the processor fan comes on at full force, NO-SYNC is displayed on the monitor, the light for the CD/DVD combo flickers indicating recognition, the light flickers indicating HD activity and then it just sits there like a bump on a log.

I have updated all the drivers I can find from e-machine and MS. After that, it will, finally, go into a shut-down/power off during shut down only (not Re-start).

I have found that if I hit the F8 key after a few (‘hold down power button) until it goes off. Then hit the power again to start. Sometimes it works and sometimes not.

    There were a few viruses and tracking files. I updated her AVG to the newer version and ran a full scan, ran McAfee STINGER and a couple different RegCleaners. They cleaned out a bunch; however, the problem persists. It seems as though that the OS can't find the boot file or the shut down cequence. Windows goes into its Shut-down mode, but, then everything shuts off before the power shut off is complete.

No sync means no video signal to the monitor. The rest sounds like a corrupted OS. This could be from a number of reasons, including a virus. If you have NORTON or MacAfee, Your open to a lot of attacks. Get AVG free, and use Mozilla instead of IE.
The reason the fans come on full speed is the MB senses a high temp on the CPU, until the bios fan control takes over after POST. This is normal on most systems.

The game has probably screwed up the configuration. They do sometimes.
Press the power button and just before the machine tries to boot press the F8 key. That should allow you to restore or repair your machine.If there is absolutely no display, get it repaired under warranty.

Hp laptop has blinking red square above touch pad, comp. won't allow for reboot or restoring to factory conditions


If you do an illegal shut down which is power off by holding down the power switch for 8 seconds. The HP computer will then boot with the scandisk program, which will restore your hdd to perfection. Windows XP or later now use 'system restore' to rearrange registry from a previous calender date that the computer used to work perfectly.

How do i log on to the safeboot mobile data security on my pc


Answer: To get into Safe Mode with Networking: 1.Log out and reboot your machine. 2.When the machine starts the reboot sequence, press the F8 key repeatedly. 3.Select Safe Mode with Networking from the resulting menu. 4.Login. If malware has changed your password, try logging in as Administrator. By default, Administrator has no password. 5.The machine will continue booting, but the Windows desktop will look different. 6.When you're finished doing what you need to do, log out and reboot back into normal mode. Hope that helps.

I have an HP DV9000 laptop and did a presentation yesterday. When I arrived at the site I had to attach the display to an LCD projector. I connected the project via a porft connector, I believe that...


I think it's probably FN+F8 that may do this on the HP laptops. The key should have a little icon on it in the same color as the function key (typically blue) that will toggle the screen from the laptop screen to the external. There are usually 3 modes to this toggle
1. Laptop screen only
2. External screen only
3. Mirrored on laptop screen and external screen

So try toggling with the FN+F8 key combination.

Also you can probably start up in safe mode to disable the external VGA toggle.

When you see the HP Splash screen, start tapping the F8 Key to bring up the boot menu. From there choose safe mode and see if you get the video back in safe mode....After that reboot and see if it will bring up the video in normal viewing mode.

Good Luck

Computer shuts down and doesnt allow to use f8. shuts down first. what to do? virus help?


Your use of "and" is confusing. F8 is not used during the shut down process; it is used during the boot up process. Since you mention F8, it is presumed that you want to use F8 to get into "Safe Mode" instead. When you re-boot a running computer, very often you will not be able to use F8, but if you totally shut down, then start from scratch, you should be able to hold the F8 key down and it intercept the boot up process to handle things properly. Don't worry if you hear a lot of beeps during the boot up process with the key pressed; it merely means the keyboard buffer is receiving more key presses than it has room for. Since they all are F8, when the boot up process looks at the characters from the keyboard, it will see the F8 key, then display the menu options to boot into Safe Mode.

Due to c00002la fatal system error problem I am unable to shut down.


Hi,

Shut down your PC by pressing restart button then immediately shutdown button, Next time when you start your PC, press F8 during startup before the window logo comes up, and choose "last configuration that worked". If the last known good configuration does not work you may have to reinstall the operating system. Visit this link to resolve this error.


Thanks..!!

Presentation mode is off appears when you try to FN F8 Dell Latitude E6500


check device manager to be sure your video card is functioning properly. If it looks good in device manager, shut off the pc, connect the external monitor/projector to the pc and start up the pc with the external device powered on. if no video from external device, then the video card/external connector is probably bad. Contact Dell if in warranty.

maybe the fn/f8 keys are not working. Can you get a safe mode boot prompt by repeatedly pressing the f8 key immediately following power up on the laptop? if no, f8 key is likely dead and you need a new keyboard. If f8 is okay, does the fn key work with other functions? if no, fn key is bad - new keyboard.

Hope this helps!
