Today my nettop started going into sleep mode (or maybe suspend/hibernate, I'm not sure on correct definition).
I'll start nettop, everything seems fine, boots into ubuntu 10.04.1, then it will go into sleep mode. power light is flashing. I click on power button to bring out of sleep mode, ubuntu greets me with login screen, but then it will go back into sleep mode within couple seconds, seems random. Sometimes I can make it back into normal ubuntu desktop (maybe 2 seconds at most), then sleep. Or when at login screen, it goes back to sleep.
I updated firmware, no effect. I've tried different plug outlets thinking a power failure/problem with my power bar or plug outlet. Doesn't help (although when I first switch plug outlets in wall it seemed to work, but since then same problem even in same plug outlet).
Not sure what problem is. I've read
some posts and people have similar problem, but their problem is they can not even get nettop to BIOS screen. I can go into BIOS and have it sit there with no power off problems.
I tried liveusb of 10.04.1, and same problem so shouldn't be a SSD problem. So now I'm hoping a 10.04.1 problem, even though it has been working fine for a week (I had to abandon 10.10 alphas due to instability in OS). I'm downloading todays ubuntu 10.10 dailylive image. If I have same sleep problem on liveusb, then I guess I should try different linux OS, and after that I'm going to assume definite hardware problem.
Sadly, not worth RMAing, although if a RAM problem I could fix that. Guess I should run ramtest to see if it shows any errors. (running now, so far no errors)
I've already got the 160gb HDD that came with it in external 2.5" case for portable storage. I think it has 1x1gb ram (according to ramtest), which if not faulty could be used in lots of other older laptops. So if motherboard/power failure, at least I should be able to salvage some parts from it. Future Shop had 4gb acer revo on for $370 couple days ago, and I have newegg 4gb nettop build in basket for $400, so can get a replacement nettop that will be 3 times faster than what I got. Was hoping this nettop would last 2 years at least. I've been looking into nettop for myself, but wanting to wait until fall for better prices, and cooler weather so it doesn't heat up any.
Nettop at newegg I'm interested in:
http://www.newegg.ca...N82E168561070722x2gb ram I would get (debatable depends on cheapest 2x2gb ram at time of purchase).
http://www.newegg.ca...N82E16820104026I would put my 60gb ssd into it from current nettop. I'm pretty sure the dual core nettops have SATAII, and thus my SSD would get full 250mb/s speed.
Sadly that nettop model is new, and only at newegg, so price is a bit high, but using newer intel atom processor. Can't find reviews for the product either (other than newegg).
If BIOS and ramtest from 10.04.1 liveusb works with no power failure/sleep, then hopefully just 10.04.1 problem with my hardware. Or some bug/crash that happened and is putting it in a sleep loop. In BIOS it has options for sleep mode. S3, something else and auto. I have on auto I think, and I never changed it before so doubt that is problem, but maybe avert it or prevent from going to sleep?
EDIT:
Also sad is that newegg had barebones atom330+ion +2gb ram nettop for $180 several days ago. Argh, of course mine has to break down after a good sale available.
Attached 4 second video of text that appears when it goes into sleep mode. This was in 10.10 daily. ramtest had no problems.
One problem I've noticed with the nettop in past couple weeks (problems with 10.10 install) was that sometimes the sound would mute and internet disconnect. So possibly a bad wire somewhere cutting power to something on motherboard? Then this causes it to go to sleep? Although the sleep problem was not present in 10.10 install. And 10.04.1 was working fine as far as I know for past several days.
Another symptom is that when it is happening lots, I notice the screen go black for less than an second, but back to normal, then about 4 seconds later I get the text error and it goes to sleep. So I would assume power failure if screen goes almost black, as if it is very quickly dimming (not monitor dimming, but screen output). I don't think it is normal ubuntu dimming when shutting down etc, it is too fast for that.
EDIT:
Still no solution, so I've hooked up my slow but trustworthy 8 year old pentium 4. I attached power meter to monitor watts. Just the tower+mouse+keyboard+wirelessusb (just power cord from tower plugged into it), it used 100 watts at peak, and 60 watts idle. 3 watts when not turned on.
So if nettop has unfixable hardware issue, looks like I'll be using the pentium 4 until a sale on another nettop. Sadly this week two sales went by on nettops, so it could be a week or two for another good sale.
EDIT:
Good news! I installed 10.04.1 onto pentium 4, everything was fine, left on for 1 hour. I installed new kernel, restarted, and upon restarting it went into sleep mode!
So I'm guessing this is some sort of kernel problem/error.
Time to use different distro!
EDIT:
changed keyboard/mouse, and now working ok. So slowy going to add new devices one each day and see which device causes computer to go into sleep mode. I'm guessing it was the 8 year old keyboard.
