I have the same issue, I think it has to do with the computer overheating. The only way I have found to avoid this is to lower the power setting to normal usage, and to leave space between the back bottom vents and the surface the computer is placed on.

This is kind of like sticking a band-aid on a gaping wound though.

My acer travemate 7720 keeps powering off without any warning

To me that sounds like it is getting hot somehow, like the heat sink is blocked with lint. The fan might be burnt out...Next time listen for the fan to come on...and find the vents where hot air should be comming out..and see if that is happening...If the fan is comming on and it is blocked up(from the inside) it still will overheat, meaning you would have to disasble the laptop to remove the lint from the heatsink.

Does my acer nplify tm 802.11 b/g/n has blue tooth capabilities

If you are talking about the Nplify software, it only concerns the WiFi features of your laptop computer, and has no incidence on Bluetooth.

If you are talking about the Laptop itself, it all depends on the model. You should find the model on a sticker under the Laptop.Most laptops come with integrated Bluetooth so you may probably have an enabled Bluetooth Laptop. To be on the safe side, search for the model of your Laptop on the manufacturer's website and take look at it's features. Be cautious though, as some models may have multiple declinations, generally a letter (or number series) more or less (eg. The Acer Aspire 7720 and the Acer Aspire 7720z have noticeable differences).

My acer aspire turns itself of after about 30min of using

Usually,, something like this is caused by a heat problem.
Things that usually heat up in the laptop are:
- the CPU (check the fan, may have to take apart to really clean)
- the Video Card (this may have a fan but usually a heat-sink, also may be dirty and full of dust)
- the RAM (usually nothing much to do here)
- the Hard Drive (this may be the problem but check other things first)

I would check the following forum as they describe how to take it apart for cleaning and also refer to a "build up" of dust in this laptop model.

Another thing would be to check the BIOS version and also check at what levels the alerts and actions are set.

Also, when using a laptop - do not cover the fan vents which may be underneath.

Good luck

Hi, when iturnon my laptop (acer aspire 7720 17')

Its better to send the laptop to the manufacturer for a repair as we find it as a genuine issue with either the board or with the monitor. There could be no issue with the OS and looks like its a genuine hardware problem. Good Luck.

Acer Asipre 5315 laptop Battery A/C supply plugged in, hit power switch and the power light blinks 2 (maybe 1 time)times but the unit does not power on.

remove the battery and power cord then remove the battery on the mother board, hold down the power button for 60 seconds to drain the capacitors, if that doesn't work it's the motherboard that should be replaced.

Acer 7720 will turn on and work for about 5 mins and shut down

In most cases I have found that this problem stems from a bad charger not delivering the proper amount of voltage. Therefore the battery doesn't ever really get a full charge even though the power indicator may say it does. I would get a multi-meter and check the voltage at the charger tip and see if the power is fluctuating. Be careful regardless, a bad power unit may spike and terminate your motherboard.
