My eMachines g620 fails to boot almost every time I turn the power on. It hangs before loading windows Vista, just a black screen hangs... It probably doesn't load up the boot files, 'cause hitting F5 or F8 on boot-up won't do anything. With patience and occasionally several hours of time, I manage to get it powered on by turning the laptop on and off. If I try to restart Windows, it powers off and it all starts again. I've replaced the battery, no use. Though, there's something fishy 'cause if I try to power the device on without power supply cord, the power led only flashes once and laptop turns off... With cord, I'm yet able to unplug it immediately after power-on. Every time I press the power on, the system wakes and I'm able to enter BIOS and the fans are on. After exitting BIOS the system powers off, no reboot. If I manage to get the system started, everything works perfectly. Because of this annoying problem I have to keep my laptop on 24/7, but sometimes I really should reboot at least for updates... Is the cause in Vista, mobo, hard drive or what?? I really appreciate your help!!

If your PC has a recovery partition: Turn it off. Before Windows logo appears (after it turns on) keeps pressing F8. Then you should see Do a system restore? Keep pressing F8. Then follow what your computer will give you.
If you have a DVD/CD drive and a recovery (reinstall too) disk: Insert it in. Turn off your PC. Turn it on again. Then keep pressing F12 or F8 (any works). After that you should see a boot-menu. Select the option which says to boot from the CD/DVD drive. Then follow the instructions.
If there is a boot menu you may have to load the CD drive from there and the restore disk will load. Check the boot screen when the PC is first turned on and look for restore option and which key to press. It is usually F10 or F11. If all else fails press F8 on start before the first boot screen vanishes and select the prompt option. then load the CD from there after you ID the drive letter.
To run the check disk utility you will need a repair disc ora operating system disc. Put the disc in the cd drive and boot fromit. You want to get to the Dos Command Prompt (Black screen with whiteletters) and type the following command: chkdsk /r Check disk will run well over an hour or two and you will notice thepercentages going from high to low, this is normal. Let it run tocompletion. Then reboot machine.
If check disk fails to solve your problem you might have to reinstall windows.Try doing a Repair Install that way you don't loose your data, documents,music, pictures, videos or programs.
In windows xp you get to the dos command prompt by selecting R for repair whenthe options appear.
In Vista and Windows 7 you want to get to the recoveryconsole and look down at the bottom of the window for the Dos Command.
Actually Its a Operating system problem. What you need is to boot from a Windows Vista or Windows 7 disk.
1. Boot up using windows 7 disk and you will be getting windows is loading files
2. Select the keyboard layout
3. Keep on hitting next until you will be getting this screen. Choose Startup Repair. Then keep on hitting next until the computer prompts you to restart. If all things fails repeat steps 1 to 3 choose System restore this time.
4. Choose Recommended Restore point keep on hitting next Until you will be getting this window below
5. When you Click on finish it will revert the settings back to the time that you selected
Have you tried a new power AC/DC convertor ? make sure you have the correct spec...see manual for power adaptor needed. Cost less if you can get a loan of one. other than this i would be looking into checking the power jack. hope this helps
