6224 gone bad

i bought a zepto 6224 in september. T5250 1,5 GHz - 1Gb ram - Gforce 860om gt. i was rly pleased with it for a long time, but then after christmas it started to get slower and slower.
i play wow alot, i went from playing this game with good fps (i know this is relative), on best settings - to max 5 fps at lowest settings, in combat.
a game like civ4 became insane to play, having to wait minutes for opening a window in the game or things like that.

so i thought a format might help - i did this - installed the same driver as when i first got the computer.

but it is still running rly rly slow. i dont know what causes this. and if the hardware has taken damage since it ran ok when i got it.

i havent dropped it or anything like that, havent been fooling with any vital settings either.

would really like to solve this problem without having to send it to zepto since i bought it in denmark and im living in scotland.

thx in advance to whoever may help

regards simon

 

My initial thought is that the cooling system is getting clogged up. The hardware will then throttle itself to keep temperatures within limits.

See this thread. What temperatures are you seeing during operation.

Get hold of a can of compressed air, and clean the fan from the side of the notebook. It should remove most of the dust in the fan. And then it shouldnt throttle, if thats the issue in this case.

 

been checking spu temp with a program named notebook hardware control - so far max is 91 C - its still slowly rising though

is that too much?

 

91C is getting somewhat warm IMO. Is that under full CPU / GPU load?

spu = ?

John

 

If that is your CPU temp then yes it is way too high. Looks like you've got a problem with heat. Probably got rubbish sucked up into the laptop. Do as Chris M said. Then see if there is any difference.

 

spu = cpu

have not been cleaning it with compressed air - dont know where to get one atm - but i will try to find out.

the link u made john - u tell to take of the keyboard and clean it that way - dont i loose my warrenty if i do that ?

90-91 is afk'ing in wow - but then again this is with lowest settings - maybe i should get some cpu stress program - instead of this wow talk...

 

Yes, you do loose your warranty if you take of the keyboard. That is why we advise people to blow air through the fan outlet on the left side of the notebook.

 

Here's a can of air. However, IMO blowing the muck back off the heatsink into the fan can only be considered to be a temporary fix. The fan will quickly blow the muck back onto the heatsink unless the muck is removed from the notebook.

As for keyboard removal and warranty, we've argued about that previously. I think the conclusion was that if you damage the keyboard then you've lost the warranty on the keyboard but the warranty on the rest of the computer is unaffected. Zepto really need to rethink their policy towards keyboard removal: It would be less expensive to give users detailed instructions on how to do the keyboard removal and cleaning of the thermal system than to have computers being shipped back to base every few months for cleaning of the thermal system.

And that UPS 3 day shipping is a genuine 3 working days. My 6024W was collected last Friday and reached Zepto today (Zepto's system now sends out an email acknowledging receipt).

got a program named Heavyload - ran it for some time - temp didnt go beyond 88 C - that i s however the same temp as if im idling in win :/

u got some other program to recommend?

 

"I think the conclusion"

hmm would very appriciate, if the conclusion was certain or not, kinda sucks to loose warrenty

 

Idle temperature of 88C You should be down in the 50's.

Does NHC Load tell you the CPU utilisation and voltage? This should be around 5% and 1V respectively. Otherwise load RMClock and use the monitoring page to see how the CPU utilisation, speed, voltage and temperature behave. If your CPU is running at full speed then either you have Windows power problem set on maximum performance or you've got some errant application or process fully loading the CPU. I always use the performance on demand power profile which lets the CPU adjust its speed to suite the workload.

first off i tried suck dust out with a vacumer - this has helped alot - its doing much better now - not sure if its as when i bought it - dont think so.

but it seems that the overall temp is lowered by 10-15 C
the RMclock is measuring about 5C less than NHC.

as i can see the cpu voltage is between 9.0 and 1.175 - or 6.0 and 0.950

i get constant warnings CPU core overheat detected - current cpu throttle level 120%??

 

Aaagh, Please do not use a vaccuum any where near your laptop. Vaccuum cleaners creat bucket loads of static electricity, which COULD fry your laptop. A can of compressed air is all that is needed. Go to maplins or PC World and get some.

 

The temperature differences between RMClock and NHC are probably caused by reading different sensors. The CPU speed / voltage data show that it is behaving properly. If you are inclined, you could using RMClock to drop the voltage (and thereby the heat). The CPU is, in my experience, likely to be stable at 9x 1.1V.

As for those constant warnings, they confirm what we have already concluded. If you are still getting those warnings after cleaning the heatsink then it's likely that the there's good enough thermal connection between CPU and heatsink (see other thread about how little thermal compound should be applied).

I've never heard that one before. It's possibly a risk in an arid climate but not in damp and humid Britain. For years I have periodically gone over my notebooks with a household vacuum cleaner with a pipe and nozzle to suck off all the muck.

John

 

As I said "COULD fry your laptop" not definately will, but I will explain my concern.....
As the air passes over the plastic pipes/nozzles it creates a charge due to the nylon content in the plastic and the friction of whatever dust/dirt you are sucking up. This creates the static charge. There is no way of preventing the static build up as the attachments for vaccuum cleaners are all plastic and most vaccuum cleaners are not earthed (double insulated).

 

The problem with the keyboard removal, is that the customer gain full acces to the motherboard, with risks of frying / destroying something.

But as John said, if the keyboard removal has been done properly, without damaging screws or the keyboard, we would not be able to see that you had removed the keyboard, and you wouldnt loose warranty.

But i would not recommend doing so. A fresh can of pressurized air through the fan outlet can push the dust out, if you do it right.

 

How does that work exactly? I've tried it on my 6214W without any noticeable results. Wouldn't the dust get blown further into the machine?

 

A minor part of it would. But most of it would go into the fan, and be thrown out by the fan, as it will spin when you blow into it.

 

But any bigger particles such as fluff won't get through the heatsink so we are quickly back to square one. This Samsung thread has an excellent photo of a clogged heatsink.

John

 

The trick is to clean it often, so fluff wont be caught in the heatsink. I have seen machines with carpet thick fluff stucked in the heatsink, and its not a pretty look.
