Acer 5733 Keeps Rebooting

[Kart Nottingham]

I have an Acer 5733: I have switched on the laptop and get a Acer logo with Press F2 to enter setup in the bottom left of screen, after about 5-6 seconds goes to a black screen and the laptops switches itself off for approx 2 or 3 seconds and then switches itself back on again and the loop starts all over again.
I have tried all the tips mentioned: Pressing power button down and F12(without battery in) no luck; I tried trying to press F2, F9, F10 and enter and just aout do it before the laptop switches itself off again - no luck, I have taken the battery off and tried all of this with power cable and battery on and off without any success. I've also tried the unlikely things having the at 45degree angles, loosening the bottom cover and all. Can anyone help further.?

Note: If this problem started after an update (or system reinstall), please make sure the laptop is not connected to the internet in any way before you use the following instructions.

Try the following...

1. Power off the laptop.
2. Power on the laptop.
3. As soon as you see the rotating loading circle, press and hold the Power Button until the computer shuts off.
4. Repeat this process a few times until you see the "Preparing Automatic Repair" screen.
5. Now you want to let the laptop boot to the "Automatic Repair" screen.
6. Click "Advanced Options" and then select "Troubleshoot".
7. Here you want to select "Refresh your PC", if you do not wish to erase data, or "Reset your PC" to erase all data and restore your system.
8. From here just follow the screen instructions until the recovery is completed.

NOTE: You will need to get into the "Advanced Options" in order to get the "Refresh Option". This choice will keep your data, but any programs installed will be lost.

Do not do a "Reset" as that will wipe all data you have on the laptop.
