Hello,

I have a very strange effect here with my Samsung R70 Laptop. I never had this with 10.3 oder 12.1.

After booting the laptop when KDE gets ready, suddenly the power supply of the laptop switches off.

Are you booting with lid open or closed (external monitor, dock station or anything)?

Lid open. No external monitor or docking station or anything else which wasn't there with 10.3 or 12.1 already.

Still ... logind has logic to check whether lid is closed after power on and suspend if it is. The idea is that if notebook is accidentally switched on in a backpack it avoids overheating it. Makes sense to verify that lid close sensor works.

The power supply only seems to have a 2 wire connection to the laptop and it would be new to me that it has some builtin intelligence or possibility to be switched off by the laptop.

...

...

Today it even switched off after repluging it in (beep in KDE and off it goes).

What strange effect is that? Power supply is just the original one, a SADP-90FH B AD-9019S.

Thx in advanve ME

if the laptop is old, this may show that the processor is overheating (security stop)

do you hear the cooler fan?

On one laptop I had the cooler fan that started at POST, but never more after that and the computer switched off

the fan logic was faulty. I just soldered the fan to the usb alim and the computer may still work (I sold it after that)

jdd

Fan is quiet. gkrellm reports just normal temperatures after I login. I know that fan ist working at higher temperatures, it is not broken. I checked the power management settings: nowhere a single word to "switch off power supply". ;-) I'd rather expect the laptop to switch off if there is a problem and not the external power supply only.

Yes. Exactly.

never seen that? do you notice an overheating of the power supply?

It just started so it cannot be overheated. Also: otherwise I guess it would switch off right after plugging it in and not after laptop starting KDE. Also I plug the power supply off and back in, KDE beeps and the power supply goes off again. But I did not find any log messages in /var/log/messages for that.

Never seen that :-(

Boot from a LiveCD and see if it does the same thing, maybe an older liveCD, like knoppix or something you have hanging around. As far as I know there is no command to tell the power supply to shut down, at least I have never seen that on any of the laptops I've seen over the years. I don't believe your typical external power supply even has the capability to be shut down. I've never even see a power switch on any of them. I suppose its possible your battery is detective and it is cutting off the charge circuit via the battery's internal thermal protection circuit. Try booting the laptop with the battery removed and the charger connected. Try booting the laptop with ONLY the battery connected. Click the Battery Monitor widget in the tray and check that enable power management is checked. -- After all is said and done, more is said than done. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I am not sure if this will help. In GRUB it does not do that. I was running the laptop in GRUB just on the dual boot selection: no switch off of power supply. Only after booting to KDE the adapter switches off sometimes.

It may be because there is no load enough. You'd have to boot to text mode, and then run something heavy, like building the kernel. Maybe compressing some files is enough.

Are there some logfiles where power management quirks are shown?

That's what a repair shop would do, it is the easiest and fastest test. It needs having spares, which a shop does. The typical person can't.

Yes. Exactly.

And it is a two write unit. I would think that it is the power supply itself which thinks that it is overloaded and switches itself off. It may be really overloaded because the laptop (maybe the battery) demands too much electricity, or it may be that the power supply is damaged.

Also I plug the power supply off and back in, KDE beeps and the power supply goes off again.

It probably beeps but it detects the power supply activity, but not because it commands it off. It is not impossible for the laptop hardware to communicate somehow with the power supply on two wires⁽¹⁾, and although I sometimes suspected this, I have never seen proof of it. A gadget might tell the charger that the battery is fully charged, but it is simply easier to block the current at the inside. But if the battery is not fully charged, there would be no reason for this. (1) superimposing a small ac signal for communication.

But I did not find any log messages in /var/log/messages for that.

If an application could do that, it would be in the original software installation of the machine. I'm guessing that would be Windows? -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

You may be seeing the beginning of the end of your power supply's life.

It was working since 2007 so that might be the case. :-(

Something is likely wrong internally that is forcing it to shut off. The best thing is to do is to replace it with another for your laptop, or better yet, one that has a much higher power capacity. If your power supply outputs 60 watts, get one that is at least 90 watts. A power supply that provides more than the minumum power required will usually work for a much longer time before it fails.

This type of power supply will typically fail within a few years time. That is only how it's designed. You were expected to get rid of that laptop within 2 years and not have to worry about the power supply. (^_^)

This laptop is running since 2007. Without any faults. Probably I should get a new power supply. Just in case. ME -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

For the record, I've never had a power supply fail on any laptop.

Me neither.

Batteries, yet, power supplies that I've had to replace have all been due to cord damage or being lost or forgotten somewhere.

I also never had a cord damage (no dogs ;-) ).

...

How old is the battery?

Same as laptop, running plugged in most of the time since 2007.

I've had batteries that spent their entire life on line

Same for me in this case.

other than brief power outages slowly lose capacity to the point where I had less than 10 minutes run time after a full charge.

Just plugged out the power supply. It says 100% and then after some while 98% and not a time how long this will go. I somehow remember that SuSE 12.1 showed the estimated time how long the battery will last with current power consumption. Also changing brightness from 85% back to 100% changes nothing. I guess the brightness control which worked on 12.1 does not work on 13.1 anymore. :-(

I've alsp seen my current battery indicator flash RED every once in a while being plugged in. On this computer flashing red means the battery state is getting critically low. Of course its plugged in, fully charged and working correctly.

(This is new with 13.2 by the way, which lends credence to your experience of this as a new "feature").

I also have the impression that power management changed since 12.1 . Not for good as far as I can say. Previously the brightness buttons worked with 12.1 out of the box. With 13.1 the display shows the % but nothing changes. Also I remember that the loudness buttons were working in 10.X but nowadays I only can change loudness from the taskbar. [...]

But in my case, the charging resumes normally.

Charging goes normally after plugging in the power supply. But charging bar says 96% and "capacity" says 92%. Does this mean that some charging electronic only uses 96% of maximum charging and the battery has only 92% if I plug out again?

I noticed something. You initially wrote:

]> After booting the laptop when KDE gets ready, suddenly the power supply of the laptop switches off.

However, the battery is still good, you say so above. If the AC power supply is bad and fails, the battery is there, so the laptop should not switch of in any case. I see no reason! It is similar to the AC going out, it is normal and no cause for poweroff, while there is battery.

And while running on battery alone, I take it that the computer doesn't turn off when you start kde.

This is starting to look a different issue. I would look at the power management logs, perhaps there is a clue in there.

I've forgotten all the posted details on this thread, so I don't know if it has ever been stated that the laptop goes down, or simply reports that the power has failed, but carries on running on battery. It could be that some time later power management will reconnect the battery. These things aren't always instantaneous. I'm currently fighting a problem on openbsd, where battery power will decline slowly as expected when running on battery, till about 85%, and then it will fall instantly to 8% which puts the machine into power critical state, and it goes to shutdown. Rebooting the laptop (without plugging it in) shows power at about 80%. So probably some software bug in openbsd pm-utils. - -- After all is said and done, more is said than done. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlSV7SwACgkQv7M3G5+2DLLoAQCfRoMX5gJGK5TKpMA/hvULdYJG LnEAnih93SVAYrmjg0EgF4b8V0lHZHK+ =DnSN -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

What goes off, the power supply only, or the laptop? ie, the laptop switches off, or does it remain running on battery? If it keeps running on battery, just replace the AC power supply unit. On 2014-12-21 13:36, Markus Egg wrote:
