M6N suddenly shuts down

Twice today while I was working on my one month old M6N it shut itself off while I was connected to AC power. I had word processing open, was doing internet browsing and printing. The other time I had word open, internet, and I was listening to a CD. Both times the computer suddenly lost power, no beeps, no screen, just turned itself off. I checked power supply and it's okay. The only thing different is that I bought a cheap wireless mouse yesterday. Could it be causing some interference? I don't have the battery in right now, I can put it back in so the power supply doesn't get interrupted, but I still want to know why my new notebook is misbehaving. I'd appreciate any thoughts on this matter.

M6NBNE with 1.6 GHz, 80 gig Samsung hd, 512 RAM (Kingbee?), XP Home

check your fan to see if its spinning, check your temps using asus probe, check and see if it dies without the mouse

Well, I suggest you have your battery in, as that shutdown could be caused by slight interruptions or surges in power, which can happen often or not depending on where you live.
And why do you keep your battery not connected? It's not gonna make the battery last that much longer, they have a limited shelf life when not being used...

I don't think the computer is running hot, the fan is working fine. I don't know how to check temp using asus probe. Is this something that's already on my computer or do I have to download it? I took the battery out because the shop that sold me the computer told me to. I've read conflicting things about whether or not it is better to keep the battery in while working on household current. Sometimes I keep it in, sometimes I take it out. I don't know about power surges as this has never happened before. I can stop using the mouse, my wrist won't like it, but I don't know what else can be causing a shutdown, faulty RAM? I dunno.

Make sure the temp is not too high to cause a shutdown.

In the window setting, I believe in Control Panel -> System -> one of the tab, you could disable system reboot on kernel error. That will allow you to see if it is a kernal causing system to crash.

Memory usually cause system reboot, not shutdown.

The only thin i could think of usually causing shutdown is temp. Most other things causes reboot.

Take the battery out, operate completely on AC, and see if that does anything.

The M6N battery release latches are very easy to bump. If the battery is in a state of half inserted / half removed, and the battery contacts are constantly being connected and disconnected from small vibrations, that may cause the symptoms you are seeing.

Heat problems will not cause a PC to "shut down". Freeze, yes. Suddenly turn off with absolutely no warning, beeps, or freezing, no.

While I generally would agree, my desktop has a setting in its bios to shutdown if it gets too hot. So this *could* be the case. (not that I think it is.)

However, you check this with a program like Motherboard Monitor, which reads out the temp sensors to windows. Then you'll be able to see if it's a consitant temp that your computer dies at.

Anyhow, I concur that it's probably a power problem.

Leave the battery in, and make sure it's seated correctly. I bet you'll have less shutdowns. (as kronos suggested)

You could have "unclean" power at your house (spikes, dips, etc). Old home wiring is usually the cause do this. I've got ancient wires in my house, so all my computer equipment is plugged through a UPS. Quite a big help with the random spiking and brownouts which would normally cause reboots.

And, as I seem to be putting in every thread, battery memory is largely a myth. Here's a link: http://www.repairfaq.org/ELE/F_NiCd_Memory.html

I have my battery in, correctly seated and just now the notebook shut itself off again. Twice. Yesterday I had no shut downs. If I take this notebook in to be looked at I know we won't be able to recreate the problem. Notebook doesn't feel hot, fan is working. I'll try to get a temp reading, but I doubt that is the problem. I've only been on for an hour doing internet stuff and word processing. This is really irritating.

Have you been through the bios? Look for anything that would tell it to shutdown...

(Now we're into guesswork)

I installed Asus Probe and it seems that my notebook's temp is at 84C/188F when I'm doing internet and nothing more. In the manual under Thermal Power Control it states that The system will shut down for critical cooling when temperature exceeds the maximum safe upper limit. When my system shut down on previous occasions I had several applications open. Yesterday it shut down 3 times today none so far. This just started early this week. The notebook is only 1 month old so it can't be clogged with dust (I have no pets). I checked BIOS, I have version 0205, but nothing else stood out (although I have to admit I'm not sure what I'm looking for). So does this sound like a heat issue? Is it back to the store now to have them look at it?

I was also told to take the battery out when using on AC, the charging circuitry gets overly hot when the system is powered up while charging. I have the extra bay battery, and if i charge both batteries at once while running the thing gets so hot that the fans kicks up to a steady, loud ,4000rpm, until i take the battery out, the fan seems to stay on. But with one battery i have no problems. I would think about sending it in for warranty service if it doesn't stop acting up. Contact the shop you bought it from and see if they can't help you. Just an idea....

By the way those are high temps, i get 55-60C when surfing and such, which is a bit high in my opinion. 84C is fairly hot, you can check and see what bios you have (F2 at startup) and try upgrading seqentially to 0205(i'm using) to 0206 to 0207, people say that 0207 has some issues with too much fan activity so you might want to stay away from that one. just a thought.

I returned my notebook to the store and they replaced it. It still runs around 65-75C when I'm surfing and the fan never seems to come on. Previously it was running over 90C most of the time and the fan was always kicking in. I noticed that my bios is now 0206, it was previously 0205. At least now the computer doesn't shut down, and it doesn't seem to go over 75C.
