Acer :: Aspire S7 392 Unexpected Shutdown On Battery Power

Nov 12, 2014

I bought an ACER ultrathin S7 392 about 7 months ago and for the last month it has been shutting down unexpectedly when on battery but not when plugged into the mains. There is no shutdown routine, crash or error message it just loses all power. A second issue which may or may not be related is that sometimes when i attempt to shutdown the unit it restarts instead. I have sent it back to ACER support to fix but I think they just reinstalled windows and when they sent it back they had not fixed the problem. I have since contacted them again and they said it was fine when it left the workshop.

Acer Aspire V3-572PG :: Random Shutdown While On Battery Power

Mar 9, 2015

I have an Acer Aspire V3-572PG (about 4 months old), and the machine shuts down randomly when on battery power. It's happened when moving it from one place to another, or with subtle shifts on my lap, and sometimes just typing triggers a shutdown. However, it doesn't happen when plugged in. Battery has been fully charged; it's not overheating; it's not the fan; it's not dust; and I've run comprehensive anti-virus scans.
 
In the past, it's taken anywhere from an hour or two before it shuts down. Last night it happened simply when I unplugged the thing from the wall ... so, no moving/no touching of the computer, but shutdown when removing plug from wall!!???

Acer Aspire 7720-6569 :: Sudden Shutdown - Power Icon Shows Full Charge And Plugged In

Oct 6, 2014

 My battery has not held more than about a 45-second charge since 2009; however, the AC adaptor seems to work fine, and the Power Management icon always tells me that I have a full (i.e., about 45-second) charge and that the AC adaptor is plugged in.  Today, just after I disabled the Acer Tour Reminder, CyberLink PlayMovie, and Microsoft Office OneNote (because I never use them and I wanted a faster startup), I moved some program icons that I didn't need or that were already on my Quick Launch tool bar into the Recycle Bin.  Suddenly, the notebook make sort of an electronic squeaking sound and immediately shut down--black screen; no lights.  
 
I unplugged it, checked to ensure the battery was properly seated, felt to make sure it did not feel hot anywhere, plugged it in, saw that the lights were showing on the adaptor and on the front left edge of the notebook, turned it on, and selected normal start; it started up again.  It ran for at least three minutes (which, because of the battery, it would not unless the AC adaptor was functioning) and then, after I moved a few more icons to the Recycle Bin, it suddenly shut down again in the same manner.  
 
I started it again and it has now been running long enough for me to look up my Acer Forum registration information and update it after resetting my password.  I am writing this on another notebook.  The Acer is still running, but I want to ensure it doesn't shut down on me when I am in the middle of a project.

i have this shutdown problem. it started since i installing windows 7 into my laptop. my computer turns of itself after 10-30 seconds after an OS boot. except on safe mode option. the computer works fine on safe mode. at first, i thought that this due to software problems. then i think i should wipe out my OS and install new OS.but unfortunately, my laptop turns of itself while installing the OS!. this sound weird isnt it?

ive tried to use multiple OS to be installed. win7, vista, and even unbuntu OS also. but the turn off problem still occurs..

ive read from other post about the thermal issues, doing some patches at BIOS download from acer websites. now, im running on v1.14 for my BIOS. still. the turn off issues still occurs.

so, ive tried to look for the hardware malfunctions since trying to look at software problems cant find a clue.

after doin some reasearch and testing, ive notice that by disabling my duo processor in device manager, the computer works fine. by using single core processor now makes my laptop works fine. but surely, im running on low state now.

should i change my processor?

Acer :: Aspire 5520 Shutdown

Sep 2, 2009

I have a Aspire 5520-5912 laptop I am trouble shooting for a relative that randomly shuts down just before, or shortly after it boots to windows.

I have tested the hard drive in my Desktop and scanned it for viruses, swapped out the memory, re applied thermal paste on the cpu heat sink and made sure it was not clogged with dust.

I think I have it narrowed down to a bad MB or CPU but was wandering if anyone else has had any issues like this and what the problem was.

Acer :: Aspire 5315 Hotspot (+ Hard Shutdown)

Jan 30, 2008

a while ago (month?) i buyed my new Aspire 5315. I installed additional RAM (Kingmax SODIMM 1024MB, DDRII533, CL4, PC4300), and after that - laptop after some time (may vary between 1 - 3hs, by room temperature and running processes, and if charger is attached or not) goes hot (at the place where ram is) and shutdowns by itself.

Here will be more detailed specs. (ask if there's something missing)

Could be the voltage wrong? As i said - it's totally new laptop, i think this wouldn't be a dust problem.

at BIOS - there is no voltage settings, and it doesn't show any temp, etc. I installed SpeedFan, it shows 35 for HDD and 50 for Temp1.

Acer Aspire 4752G :: Do Restart Instead Of Shutdown Since Windows 8.1 Update

Oct 4, 2014

I cannot turn off my acer laptop since windows 8.1 update.. whenever i do shutdown, it simply just restart after shutting down.. i dont know how to turn off my laptop.. also sleep and hibernate seems not functioning, in a couple of seconds it awakes again..
 
I tried the every thing about the power management to untick something about fast startup.. still no luck
 
And i forced to shutdown my laptop during startup but it cause me a problem.. It wont power on.. and it seems dead but when i plug the power adapter the battery is charging but no signs of powering up(no power led, just battery led) whenever i press the power button.. i tried dispersing the static electricty but no luck.. the only option that solve my problem on not powering up is to disassemble my laptop and remove cmos battery. then i assembled it back.. it shows 1 blink of power led whenever i plug in the ac adapter without the laptop battery plugin.. and then it powers up again after i press the power button.. what a relief.. but it doesnt fix my shutdown problem..
 
the only thing i havent tried is BIOS update.. but im having problem right now..
 
i tried last year to update my BIOS after that it went wrong the black "screen of death" they call.. so i sent my laptop to service center.. and it fixed!..
 
I tried lately to update my BIOS but it says that i have already an updated BIOS version 2.19.. i guess this is the bios version installed by service center.. how can i apply the BIOS posted on ACER website with the latest version 2.15?
 
If i want to turn off my laptop, i simply close the lcd monitor to remain it in sleep mode..

Acer :: 1410-2285 Unexpected Error And Restart

Nov 29, 2009

I have a Acer 1410-2285 with the dual core U2300 processor running Windows 7 (64 Bit). I am having a what seems to be an excessive number of blue screen error shutdowns/restarts (2-3 per day). This seems to happen the most often when the notebook is asleep and I wake the machine up to the "Windows did not shutdown properly message" but occasionally I do see the BSOD when I am using the machine.

The only modification I have made to to the notebook was to install 4GB of PC6400 ram. I updated the drivers with what Acer has posted on their website, but i have not tried to install the non-Acer drivers.

Acer :: Unexpected Error From The Acer Arcade And It Won't Run

Jan 10, 2009

Was using the Acer Arcade and was informed about the latest patch by the Live Update.

I ran the install patch and during install the McAfee informed me that two of the files were trojams and had to be removed. The files were CL26934.RRA and CLDO7416.RRA, so now when I stick my blu-ray into the drive I get an unexpected error from the Acer Arcade and it won't run.

So where did the files go, and why would ACER put out a patch that conflicts with the pre-installed anti-virus?

Acer Aspire E15 :: Start Running 8.1 Won't Turn Off Wireless Adapter On Shutdown Preventing Net Access

Jan 8, 2015

I have also tried disconnecting from network and turning off wifi from the signal strength icon as well prior to shutdown.  When the adapter stays open when I return to the laptop and connect again it shows that i have been connected via the adapter for days at a time. This eventually leads to the connection being clogged up and causing timeouts preventing me from connecting to the net. I stopped ittwice  but dont know what I did.

Acer :: Low Battery Shutdown. Why Is It Classed "Disruptive"

Jul 9, 2009

Vista HP

Have my critical battery level set at 5% and "shutdown" as the action to take. I reached this point yesterday and the laptop powered down OK, but I notice that the reliability monitor classes this as a disruptive shutdown.

Why ? It's just doing what it's supposed to do.

Is there any possibility of file corruption or anything. It seemed to shut down very smoothly.

Dell XPS L702X :: Shutdown And Won't Power Up?

Dec 12, 2014

I have a Dell XPS L702X that I bought June of 2011.  It has been working fine up to this point.  I ended up replacing the battery but other that that it has been a dependable champ.

Today I upgraded the video drivers.  I fired up World of Warcraft and was checking out the new settings when the laptop just shut down.  I tried the power button but nothing worked. 

I unplugged it from the wall, removed the battery and pressed the power button for ten seconds. I put the battery back in, plugged it back into the wall, still no power up. 

The wall socket is good, the power supply is good (i get the glowing LED at the end of the power cord) and (as stated) the batter is practically brand new (got it a few months ago)

I'm guessing power supply or motherboard failure.  If this is true how much am I looking at to get it fixed? or am I better off buying a new laptop?

Acer Aspire 6930 :: Will Not Power Up Even After Power Reset

Oct 13, 2014

I have an Aspire 6930 that suddenly died and will not power on.  The LED power button was dark and unresponsive.  I performed a power reset and the blue light on the power button came back on until I pressed the button to try to restart the laptop.  When I did that, the blue LED immediately went dark and stayed that way until I did another power reset.  It never gets to the point of anything powering on.  Is it a problem with the battery or it the laptop toast?
 
This is a real bummer since I just replaced the hard drive a few weeks ago and replaced Windows Vista with Linux Mint (which btw is blazing fast compared to Vista).

Dell :: New M1530 Random Shutdown Only On Battery

Feb 6, 2009

New British poster here, please be gentle ;] !

I'm glad I found some fellow XPS users, maybe you could give me some advice.

I got my new(ish) M1530 yesterday (refurb from Dell Outlet, saved me 200).
Initially I was very pleased, its a lovely machine, but I then found a problem - its the curse of the random shutdown!

I first noticed it when running 3dMark this morning to demo the XPS.

It happens fairly consistently after a few minutes; the machine doesnt feel hot.
I phoned Dell support (took 1.5 hours) and they/we found it shuts down in the diagnostics tests too.

Conclusion: Replace motherboard, engineer booked.

However I have discovered it only happens when its on battery power - everything is fine on AC power.
