Heating issue

Created: 13 Nov 2012 • Updated: 23 Nov 2012 | 6 comments
This issue has been solved. See solution.

We are rolling out EV10 SP2 to the organisation.  So far in pilot we have deployed to 10 users, all of whom are laptop users (90% of the org use laptops).  Using Outlook2010 and Exch 2010.  On 5 of the laptops including my own which are around 2-3 years old, when Outlook does a sync to Virtual Vault, the Outlook process goes from 30% to 60% and overheats the laptop (about 105 degrees C) for an extended period of time.  In my case it would shutdown after several minutes of use, i had to remove from the dock and stop the sync.  I had the hardware vendor replace a heat sink and it now works ok, not getting over 30%.  This happened on 5 of the 10 laptops.  The obvious cause looks harware related but it is a bit of a coincidence that the EV VV sync pushed these over the top in the space of 4 weeks.  I'm hesitant to roll out EV to the other 1200 users at the moment until this problem is identified.  I realise the issue is most likely hardware related, but could also be linked to a MS patch, the EV add-in, or just about anything else you can think of.  Just wondering if anyone has seen such behaviour?  We will be logging this with the hardware vendor.

Thanks.

I've not heard of such a thing, but its most likely disk usage that causing it, because not only do you have EV downloading large amounts of PST files, creating XML and INI files, but you may have Antivirus scanning each item and you may also have Outlook Instant Search and Windows Desktop Search all hitting the items at the same time.

Only thing i could suggest is a decent Fan Pad!

Hey JW, I have noticed that when it comes to VV, it only deals with 1-2 emails a second, at least that's what the details tab tells me.  When syncing after an import, the content is already there, so it's just updating header cache.  As you say, other processes may want a piece of the action, but I would have thought it would handle it ok.  It's running on an SSD, but the fans aren't the best, particularly when docked.

Well it could also be that because its using more CPU, more disk, more memory its also pulling more power for each of those as well... I think your best bet may be to run a perfmon and anything that might be able to gauage the CPU temperature and fan RPMs

Also you could be doing a lot of page swaps on the VM as well

this is pretty unusual. sounds like the increased activity on the laptops has exposed a major flaw in the hardware/cooling/or lack of cooling as it may be. i once had to deal with a huge batch of bad capacitors that made it into dell machines and caused them to blue screen or some completely die. needless to say the common applications were blamed at first but obviously there's no direct correlation when you lay everything on the table and really look at it.

Usually, the CPU generates most of the heat, so seems to be perfectly good candidate for the cause. Try to use a CPU Burn-in / stress test tool to keep it at 100% for some minutes, and see what happens..

I agree with MichelZ.. in the end your issue load on to the machine, and it's overheating.  It's not a software problem.

 

Try installing a recent game, and play it for a while ...  that'll have the same effect, I'm sure.
