For me three years is about the time I consider doing two major
service
things to laptops.
1. Replace the CMOS battery. One thing you might consider doing right now
is to reset all the CMOS variables to their default values. If a battery
is low the values can change on their own and create strange problems that
go away when the default values are reloaded – until – the machine is
turned off again (and perhaps left for a time) so the battery voltage goes
low and the bits slip again. Anymore I consider replacing the battery
every other year.
AFAIK CMOS battery on my laptop Thinkpad T420i is on the motherboard. It is
too much effort to replace the CMOS battery. I can certainly look into it.
Thinkpads have really great battery life. After using this system for 3 years
battery life is still quite good. I may want to save battery replacement money
in future laptop though.
2. Clean and/or replace the cpu/gpu fan and heat-sink assembly. The
accumulation of gunk in these assemblies (often combined in a laptop) is
dependent upon how much use the machine gets and where it is used. Blowing
air through the assemblies may or may not be good enough. Local changes in
air temperature, humidity, and altitude can make quite a difference in how
fast heat is removed from the active components. As well sometimes the
heat sink compounds degrade and/or mechanical issues change the heat-sink
to cpu/gpu fit.
fwiw
Advice taken.
I think Baloo the new KDE file indexer might be at fault here. Whenever I
leave my system and come back I see two major processes baloo_file and
baloo_file_extractor are always on top. And system temperature is around 90C.
Once system temperature is that high it takes a while to get it down. Not to
mention Linux tends to be very bad for multimedia stuff. Anytime you watch a
youtube video there is a good chance that system might shutdown due to high
temperature.
