Acer Aspire 7720Z notebook
shuts off for no apparent reason !
keyboard is warm near the mouse pad !

I solved this problem
I found it to be a OVERHEATING CPU
and a reoccurring event with this particular laptop
it is the bus and cpu over heating
( a long shiny metal bar looking thingy hooked to the motherboard leading from the CPU)
dust and debris collect in a small vent duct that is feeding air from the cpu fan into the bus heat sink and out.
I removed the plastic bottom from my laptop, a middle piece that covers the cpu fan.
(' I'm not a tech with a fancy shop so i did it the home user way')
I used my household vacuum and a horse hair paintbrush to clean off the fan and remove collected dust particles.
I put my vac hose close to the cpu fan and a blast of dust poofed out and then sucked up the hose...
I then held the brush against the fan and removed much more dust as it spun from the vacuum.. then I held the hose tightly against the fan opening and sucked the dust out of the duct over the bus...
i cleaned my keyboard too put it all together
it worked, but it happened again in six months....
I live in a dusty environment....

Sounds like the power drained from the battery. Were you running it on battery power when it happened? Try leaving it off with the charger on for awhile and let it recharge.
If that doesn't help, try removing the battery and charger, press the power button and hold for about 20 seconds. Then reinsert battery and connect to charger. start up. If no joy, try removing battery and connect charger only..
If you're getting sounds or signs that it's attempting to boot but isn't fully starting, write back with the details...

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

    I'm sorry to hear that. Please see Acer support documents here and here. Other FAQ's here.

    Please insert the battery and connect the charger, then let the battery charge overnight with the laptop powered off. In other words, try to charge the battery with the computer off. You may have a problem with either the ac adaptor or the battey.

    Battery pack
    The computer uses a battery pack that gives you long use between
    Battery pack characteristics
    The battery pack has the following characteristics:
    • Employs current battery technology standards.
    • Delivers a battery-low warning.
    The battery is recharged whenever you connect the computer to the
    AC adapter. Your computer supports charge-in-use, enabling you to
    recharge the battery while you continue to operate the computer.
    However, recharging with the computer turned off results in a
    significantly faster charge time.
    The battery will come in handy when you travel or during a power
    failure. It is advisable to have an extra fully charged battery pack
    available as backup. Contact your dealer for details on ordering a spare
    battery pack.
    Maximizing the battery's life
    Like all other batteries, your computer's battery will degrade over
    time. This means that the battery's performance will diminish with
    time and use. To maximize your battery's life, you are advised to
    adhere to the recommendations set out below.
    Conditioning a new battery pack
    Before you use a battery pack for the first time, there is a
    "conditioning" process that you should follow:
    1 Insert the new battery without turning the computer on.
    2 Connect the AC adapter and fully charge the battery.
    3 Disconnect the AC adapter.
    4 Turn on the computer and operate using battery power.
    5 Fully deplete the battery until the battery-low warning appears.
    6 Reconnect the AC adapter and fully charge the battery again.
    Follow these steps again until the battery has been charged and
    discharged three times.
    Use this conditioning process for all new batteries, or if a battery hasn't
    been used for a long time. If the computer is to be stored for more
    than two weeks, you are advised to remove the battery pack from the
    Warning: Do not expose battery packs to temperatures below 0°C
    (32°F) or above 45°C (113°F). Extreme temperatures may adversely
    affect the battery pack.
    By following the battery conditioning process you condition your
    battery to accept the maximum possible charge. Failure to follow this
    procedure will prevent you from obtaining the maximum battery
    charge, and will also shorten the effective lifespan of the battery.
    In addition, the useful lifespan of the battery is adversely affected by
    the following usage patterns:
    • Using the computer on constant AC power with the battery
    inserted. If you want to use constant AC power, you are advised to
    remove the battery pack after it is fully charged.
    • Not discharging and recharging the battery to its extremes, as
    described above.
    • Frequent use; the more you use the battery, the faster it will reach
    the end of its effective life. A standard computer battery has a life
    span of about 300 charges.
    Installing and removing the battery pack
    Important! Before removing the battery from the unit, connect
    the AC adapter if you want to continue using your computer.
    Otherwise, turn off the computer first.
    To install a battery pack:
    1 Align the battery with the open battery bay; make sure that the
    end with the contacts will enter first, and that the top surface of
    the battery is facing up.
    2 Slide the battery into the battery bay and gently push until the
    battery locks in place.
    To remove a battery pack:
    1 Slide the battery release latch to release the battery.
    2 Pull the battery from the battery bay.
    Charging the battery
    To charge the battery, first make sure that it is correctly installed in the
    battery bay. Plug the AC adapter into the computer, and connect to a
    mains power outlet. You can continue to operate your computer on AC
    power while your battery is charging. However, charging the battery
    with the computer turned off results in a significantly faster charge
    Note: You are advised to charge the battery before retiring for
    the day. Charging the battery overnight before traveling enables
    you to start the next day with a fully charged battery.
    Checking the battery level
    The Windows power meter indicates the current battery level. Rest the
    cursor over the battery/power icon on the taskbar to see the battery's
    present charge level.
    Optimising battery life
    Optimizing battery life helps you get the most out of battery
    operation, prolonging the charge/recharge cycle and improving
    recharging efficiency. You are advised to follow the suggestions set
    out below:
    • Purchase an extra battery pack.
    • Use AC power whenever possible, reserving battery for on-the-go
    • Eject a PC Card if it is not being used, as it will continue to draw
    power (for selected model).
    • Store the battery pack in a cool, dry place. The recommended
    temperature is 10°C (50°F) to 30°C (86°F). Higher temperatures
    cause the battery to self-discharge faster.
    • Excessive recharging decreases the battery life.
    • Look after your AC adapter and battery.
    Battery-low warning
    When using battery power pay attention to the Windows power
    Warning: Connect the AC adapter as soon as possible after the
    battery-low warning appears. Data will be lost if the battery to
    become fully depleted and the computer shuts down.
    When the battery-low warning appears, the recommended course of
    action depends on your situation:
    Situation Recommended Action
    The AC adapter
    and a power
    outlet are
    1. Plug the AC adapter into the computer, and then
    connect to the mains power supply.
    2. Save all necessary files.
    3. Resume work.
    Turn off the computer if you want to recharge the
    battery rapidly.
    An extra fully
    charged battery
    pack is available.
    1. Save all necessary files.
    2. Close all applications.
    3. Shut down the operating system to turn off the
    4. Replace the battery pack.
    5. Turn on the computer and resume work.
    The AC adapter or
    a power outlet is
    unavailable. You
    have no spare

My acer aspire 7720 wont come on. i tried it without the battery just the charger but nothing. i plug the charger with the battery and it charges the battery but wont turn on.

It sounds as though you have a problem with the power button itself, this is on a small cicuit board beneath the top panel where the button is situated, these boards are not too expensive and eay to change providing you are competant with a screwdriver. If not I would recommend that you get a technician to take a look.

Acer Aspire 7720 shut down, no power light, battery and supply check good. Tried the power reset still no power light with AC supply. unit completely dead. Do I stick a fork in this one?

The laptop's AC power jack is probably damaged. All you have to do is put the fork aside :D, unsolder the old power jack and solder the new one in. If you are not good at soldering you can get it done by a qualified professional. Its a 5 minute Job and a pretty inexpensive repair.

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.

2.Check after removing the battery with adaptor only.
3.If then also it is not working check whether the num lock is responding if yes then this is a RAM refixing or changing issue otherwise a motherboard issue if the adaptor is working fine.
