AA1 Ubuntu Netbook shuts itself down

[robozoid87]

Hi all,
After being recommended installing Ubuntu Netbook Remix for my acer aspire one to replace Linpus, it ran brilliantly and i was able to install most of my software just like it had been before.
After about a month into installing Ubuntu, my laptop turns on, boots, and shortly after connecting to the internet it shuts down.
i've tried reinstalling using live usb, and running via the mains without the battery. it does the same thing with each.
help pleease, thanks in advance

Assuming it ran ok for some time and you didn't intsall anything suspicious, then I have to think you are experiencing some sort of hardware problem.

What is the temp before it shuts down. Is the fan running?

My Acer Aspire One running Ubuntu 10.04 Netbook runs at about 50 to 60 degrees Centigrade Depending on where it is sitting (hard cool table surface or my lap) and what I am doing with it. Sounds like yours is running hot.

If you're running it on the bed, it could be that cloth is blocking the cooling vents, and/or maybe the heatsinks are plugged full of dust..? A dust-plugged heatsink can nuke a CPU in a couple minutes.. During an OS install I had a tower that I found in the junk explode its CPU's plastic top off, showing the printed circuits, from overheating from its heatsink being plugged with dust...

You can't clean nor lubricate dust from fan bearings.. That dust turns into abrasive carbon, and destroys the fan's bearings in a few months.. Is why corporations spend $millions to create and maintain dust-free computer rooms...

Running a computer while sweeping, the fans suck-in airborne dust... Best to dust, sweep, and vac with the PC turned off...

Running a PC near a heater or heat vent, the fans heat what they're supposed to be cooling...

Running a PC near a cold air vent, the fans will suck-in a lot of dust...

Off the top.. Is there tape covering the vent holes..?

Running a PC outdoors is a bad thing, especially in the city where the air is saturated with dust raised by vehicle tires and by wind currents from moving vehicles...

I'll wager that you need to have the fan replaced, and maybe the CPU too...

I think the problem is that the fan is probably proken or not up to full standards because that happens with mine. after its shut down find the grill/vent on the bottem and check if its hot if it is your fans broken and you'll have to replace the fan/motor

Just a shot showing my temps on my AAO. With chromium browser open with multiple tabs running Ubuntu 10.04 Netbook (Gnome Desktop, not the UNR Desktop)

thanks for replying,
i have just installed limewire, which i'm guessing, if there is a dodgy software issue, its limewire thats causing it.
replying to rokytnji, gnome doesn't show the temperature of the computer like it does with yours (on the screenshot you have provided). if you have any suggestions to how to find out the temperature of the computer any other way, that would be extremely helpful.
thanks again

If you have lm-sensors installed (check synaptic) you can do

biker@biker-laptop:~$ sudo sensors-detect
[sudo] password for biker: 
# sensors-detect revision 5818 (2010-01-18 17:22:07 +0100)
# System: Acer AOA150

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): yes
Silicon Integrated Systems SIS5595...                       No
VIA VT82C686 Integrated Sensors...                          No
VIA VT8231 Integrated Sensors...                            No
AMD K8 thermal sensors...                                   No
AMD Family 10h thermal sensors...                           No
AMD Family 11h thermal sensors...                           No
Intel Core family thermal sensor...                         No
Intel Atom thermal sensor...                                Success!
    (driver `coretemp')
Intel AMB FB-DIMM thermal sensor...                         No
VIA C7 thermal sensor...                                    No
VIA Nano thermal sensor...                                  No

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): yes
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'...                   Yes
Found unknown chip with ID 0xfc11
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'...                   No
Trying family `SMSC'...                                     No
Trying family `VIA/Winbond/Nuvoton/Fintek'...               No
Trying family `ITE'...                                      No

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): yes
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): yes
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): no
Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver `coretemp':
  * Chip `Intel Atom thermal sensor' (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO)yes
Successful!

Monitoring programs won't work until the needed modules are
loaded. You may want to run '/etc/init.d/module-init-tools start'
to load them.

biker@biker-laptop:~$ sensors
acerhdf-virtual-0
Adapter: Virtual device
temp1:       +49.0°C  (crit = +63.0°C)                  

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +30.0°C  (crit = +90.0°C)

Hope that Helps.

ubuntu has decided to stop booting. the laptop is freezing, so my best guess is that software has destroyed it.
any suggestions on how to keep the laptop on long enough to take the software off?
thanks

[rokytnji]

Wrap it in Plastic Bag and put in fridge. Cool it down. 30 minutes maybe.

Fill a Ziplock bag with Icecubes. Make sure outside of bag is not wet. Set Laptop on top of bag.

Reinstall Ubuntu with Pendrive. Don't reinstall Limewire. (never liked it anyhows. just my opinion) There are better ways to download music. At least for me. I won't go into how to tell you how though, as that is up to you (google it).

Lastly. To see temp simply in terminal with Ubuntu on AAO

biker@biker-laptop:~$ cat /sys/class/thermal/thermal_zone0/temp
51000

51000 stands for 51 degrees Centigrade. I have had this netbook running all day.

(just a suggestion. Take it or leave it)

I would also suggest Installing Ubuntu Netbook instead of Ubuntu Netbook Remix. You can run the regular Gnome Desktop with sensors in the taskbar with Ubuntu Netbook.

At Login Screen after install. Go to sessions tab after typing in name. Select Gnome from sessions. It will stick. Never liked the UNR interface as it is buggy and limited (my opinion only).

Good luck with it. Rok
