It may have over heated. It should work after it cools down.

7720 runs fine off battery ,but will not run off ac adapter ac adapter has been checked and has the right amount of voltage and amps


Adapter: see if you can get a duplicate adapter from someone and try theirs. Your PS has a fault which could lead to damage to the Video portion and down the road, burn out the CPU.

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.

Sai.

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.

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.
procedure:
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
and.......
viola........
it worked, but it happened again in six months....
I live in a dusty environment....

Aspire 7720-6569 laptop automatically shutoff and won't turn on.


hi,
Please try following DIY
1.Please remove the battery and then press the power button for a minute without connecting the adaptor then refix the battery and check whether it is working.
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.
