halp Sager NP4791: EXTREMLY HOT

Hi!
does anyone know whats wrong with my NP4791?
it turns off without any kind of notification. (not even a bleep)
i guess its because it can go REALLY HOT according to SpeedFan
about 73C (163F) which is really hot for my taste

i bought it back in 2005 and it worked like a charm.
but the "INSTA-SHUTDOWNS" started off like one year ago,
and it recently became a standard (mis)behavior.

i was foolish enuff to have the notebook out of AC Power while turned off
which sucked the battery to death (i guess).

now without AC power the book is working for like 2-10 minutes before
reaching 10% battery

beeing a wiseguy i bought a second battery back in 2005 if the first one die.

trying the second battery a good hint?

thanks in advance for any help

 

Have you tried cleaning the notebook? (Intake and exhaust) It could likely be dust and other debris is preventing the notebook from being adequately cooled.

If you have not, Gophn has a good "How To" clean your notebook out.

 

thanks for such a fast reply!
i will look for that HowTo as the vents are stuffed with dust
which could be the reason for the overheating

 

what is a NP4791? I couldnt find it at sagernotebook.com?

 

If you are overheating... usually any temp over 90C degrees is bad.

when was the last time that you cleaned out the fans and vents thoroughly...?

if never, then thats why.

1) remove battery
2) remove/unscrew the panels on the bottom of the notebook to get to fans and vents
3) use flashlight to look through vents for the dust (if you cant see the light on the other end, then the vents are clogged up)
4) go outside, get some compressed air (cans or compressor @ 50 PSI) and give the vents a good airing out all directions (concentrating on the vents)
.... you might want to brace the fan blade(s) when airing it out (with anything to prevent it from spinning out too much)
.... or use short bursts (1-2 secs) of air instead of bracing the fans.
5) go get some Q-tips and swab the fan blades and the area around it
6) then go do a second airing with compressed air (all directions again focusing on the fans and vents) to push out the dust that was dislodged from the Q-tips

7*) Now go use the flashlight again and look through the vents (shine the flashlight from the fan, you look through the other end) for anymore dust clogs.

8) Then start up the notebook... and let the fans cycle up (use the Fan Toggle at max speed if your system has it) to push out any other dust that might have been stuck.

If all goes well you should be able to close up the notebook and...

you're done.

*repeat this step until its cleaned out.

Thats pretty much it.

Just make sure to do this every two-three months... it should take about 15-20min per cleaning if you want to be thorough.

Gaming notebooks are a new thing, you must realize that you have to take some extra care of them over typical use notebooks:

1) Battery: to maintain the longevity of any rechargeable battery
- you must NEVER overcharge it [especially for long durations of time] by keeping it plugged into AC
- when it reaches 100% you should unplug it and let it discharge to 5-15%, then plug it back to power
- OR you can just charge it to 50%+ and remove the battery and store in cool place.. not the fridge [remember to use it occasionally 3-4 time a year to charge and discharge it].

2.) Heat: to prevent a healthy notebook from overheating
- ALWAYS use the notebook on a clean, hard & flat surface
- RECOMMENDED to be used on a notebook cooler... namely the Zalman ZM-NC1000 or ZM-NC2000
- check your fans underneath occasionally (at least once a month or two) for any dust clogs [clean them out with Q-tips and air cans/compressors]
- ALWAYS monitor the temps (CPU, GPU, HDD, etc..) to watch for fluctuations, which would indicate overheating by dust usually
(for Clevo notebooks) use the Fan Toggle to switch all fans to Max Speed when gaming and such.

By doing these simple things, your entire system will easily last for more than 3 years.

 

Gophn i just read ur sig? U seriously think people should unplug thier battery from thier system when they are using it on AC power? seems a little excessive to me tbh.

 

it's what I do. I practically never take my laptop out for a stroll, so there's no need to keep the battery in there wasting away its life.

that said, the 15" portability of this thing will come in handy though

 

I only give a warning for mainly those that leave their systems charging all the time (24/7)... that would diminish the battery's lifespan.

I recommend for those that always leave their systems plugged in, to just remove the battery.

I have my D900K for over two years, never needed to remove the battery. I just make sure that its not overcharged, by unplugging it overnight and unplugging it when it is full.

then plug it back in when its low.

I've been doing this for over a year and a half now... my battery is still as healthy as it was when I got it... and I got used to watching for the battery charge.

Even a number of notebook utilities have given the same warnings.

I.E. Levono's.

 

Yea but if its always plugged in, the battery isnt always charging..... Its just always 100%

 

depends on the notebook's low level programming to cut off charging when it reaches 100%

some switch off the AC to discharge the battery a few % then charges it up to 100% again.

most, however, do not have either ability.

 

whoa!
lotsa replies which spawned a discussion about cleaning
policy on highend notebooks

thanks guys im gonna clean this dusty one of a mess up
and get myself the Zalman cooling sys, which seems to come VERY handy
when facing a really hot notebook.
