burning laptop Dell Laptops   Thermal Issues, Laptop Replacements & Unacceptable Customer ServiceWhat do you get when you cross a Dell laptop, overheating issues and Dell customer support…  If you can spare 5 minutes for a quick read I can answer that. In short you get a lemon, a load of stress and a long time with an inoperable machine. For any of you that own a laptop, Dell or otherwise, I write this article to outline my case and publicly tell the tale of what I have gone through. I not only welcome your thoughts as comments but also your stories of issues you have faced with Dell or even another manufacturer.

To set the scene in mid 2009 I purchased a shiny new Dell M4400 Precision Mobile Workstation, at $7500 AUD it really was the top of the range and bleeding edge system which I believe was the first Dell business laptop to contain a quad core CPU (the Intel Q9300). After moving houses I began to notice thermal issues with the laptop (about mid 2010), in my previous house I was always in a very warm room so during the summer months had an air conditioner running right next to the laptop) therefore it was not till I moved to a new house that these issues became apparent.

Any time the laptop was used in a room with an ambient temperature above ~23-24 degrees Celsius the laptop throttled the CPU by 87.5% (rendering it unusable) and while it was in a usable state would output heat that would burn your hand if you left it in front of the vent for more than a couple of seconds. In October 2010 after doing my own diagnosis and deciding there was a genuine hardware issue I logged a call with Dell under my 4 Hour warranty (which I paid a large premium for which entitles me to a technician and parts on site within 4 working hours). After breeching the service level agreement (SLA) due to part availability and having to get parts from interstate the tech replaced the heatsink and fan in the laptop in the hope that this would resolve the thermal issues. Over the coming months this proved to be an ongoing issue and therefore I logged a new call to Dell.

This brings us to the fun part:

  • Dell on site to replace CPU, new part is a dud and tech has to come the following day with a new part as Sydney only had a single unit in stock
  • New CPU does not resolve issues, on site tech admits there is something seriously wrong.
  • On site tech boots the laptop the moment the computer booted up the CPU was idling at 65 degrees Celsius, the rated maximum for the Intel Q9300 is 70 degrees Celsius. The tech from dell on this occasion looked at me and said the guys back in the office have no idea how you have worked for this long on the laptop… he agreed it was obviously a fatal design flaw and the Dell M4400 model was never designed to handle the thermal dissipation required to cool the quad core CPU.
  • Dell takes my M4400 offsite for two days for internal testing. They attempted various CPUs to try to rectify the thermal overheating. Alas they were not able to and in turn were able to conclude that I had a wonderful $7500 Lemon.

After all this I was tossing up between a refund or a replacement system and as Dell informed me that the refund would only be ~30% of the purchase price I opted for the replacement. I was informed this would be about 10 working days (or at least that was my understanding, the account manager said today that she stated 10-14 working days, YAY for he said/she said). Regardless of this fact after the order FINALLY being placed today I was informed that the laptop would in fact be 14 – 21 working days… Now… a little maths for you. I pay through the *nose* to get a 4 hour warranty, I am then told it doesn’t cover a replacement laptop and that requires additional time… something that I never believe it stating it was restricted to. However even if we say take 10 working days at 8 hours a day, a 10 day delay is over 20 times the 4 hour warranty I signed up for.

The puzzle that Dell does not seem to appreciate is that when I purchased this Laptop, I paid a massive premium to, according to my understanding, resolve any issues within 4 working hours. If there has to be a slightly longer duration to cover lemon replacements… OK I can accept that however I fail to see how 28-42 times the duration that I deemed to be appropriate repair and resolution (i.e. 14-21 working days x 2 possible repair windows every 8 hours for a working day) is deemed to be a FAIR time for replacement.

After speaking once again to the account manager today I was told to blatantly and rudely to “deal with it” and if I wanted to I could “take it further”. So I have, called up customer care and requested a call from the complaints manager, and I have logged a call to fair trading. So as I have had to deal with these consistent issues, constant warranty (SLA) breaches, constant unavailability of parts and the fact that Dell really does not seem to be able to get me a replacement system in a fair and reasonable time frame I decided I had to share.

What I ask of you fine reader is… what would you consider to be a fair time for replacement… I told them 5 to 10 days as I realise they need to get the order from Malaysia but even 10 working days I feel is pushing far beyond reasonable when you consider that upon purchasing the system originally I did so with the understanding that any issues would be resolved in a very timely manner. I use the system for work, study and personal affairs and therefore without a working laptop I struggle immensely.

So go nuts… what are your thoughts?

If you have ever experienced thermal issues, other heat issues or general slowness on a Dell Precision Laptop then this little gem might be right up your alley. I can confirm that this works on a Dell M4400 laptop but I suspect it will work on a variety of other Dell laptops or mobile workstations as well. This may be useful if you are suffering suspected CPU Throttling, suspected heat issues, or anything else that may be related to the speed/heat/health of your laptop CPU.

WARNING: This should only be done if you are a savvy with IT and have knowledge surrouding the precice inner workings of the system. In other words if you are not an IT Professional/Expert you should NOT be doing this I guarantee it will not make any sense.

On your laptop keyboard (not an attached keyboard it must be on the laptop itself):

  1. Press and hold Fn (function key) and Shift
  2. While holding the above two keys press the following numerical sequence “15324″
  3. Let go of the Fn and Shift Keys
  4. The lights at the top of the keyboard should now be flashing or at least responding differently than they would normally
  5. Then you can press Fn and the letter R to get a wealth of information relating to the thermal health of the laptop.

I know that Fn + T will also work with some additional information I am not sure what other little gems are hidden under this mode.

PLEASE NOTE: I put this here purely for educational purposes, you go into such engineer modes at your own risk and I can not be held responsible for what you may break if you do.

iStock 000009232138XSmall Edit Intel network interface on Dell notebook dropping outIf you are suffering from an issue that causes your network connection to drop out when your computer idles then you have come to the right place.I have been using Dell notebooks for many years, and one little trick that I picked up quite some time back relates to the drivers for network cards on Dell Laptops.

Most commonly I have found this issue with the Intel 82567LM Gigabit Ethernet adapter however it is entirely possible that it affects other models too.

What Causes It:

This behaviour is actually a “feature” of the driver and is designed to drop it from 1 gigabit to 100 megabit mode which in turn saves power (on the assumption that you do not need 1Gbps of throughput while you aren’t physically at the machine). I have only ever experienced this with the Intel Gigabit cards (Intel 82567LM) but it may happen with others as well.

How to stop it from happening:

You will need to get a new driver directly from the manufacturer. As I mentioned I have only ever experienced it with the Intel ethernet interface so if you pop over to the Intel Download Center you can grab the drivers from there (if you are having problems specifically with the Intel 82567LM click here to get the latest drivers).

When you have installed the new driver go into the Device Manager and select the network card. Open up the properties panel and select the Power Management Tab, then uncheck the “Reduce Speed during System Idle” checkbox and you should be sweet.

Why you have to get a new driver:

Dell in their infinite wisdom decided that with all the network interface drivers they put out they will automatically enable the above setting and REMOVE the ability for you to change it. Therefore in order to gain the functionality to change the setting you have to use the manufacturer driver not the Dell OEM version.

I have been using this little workaround for at LEAST the last five odd years and have yet to have an issue with using teh Manufacturer Driver over the Dell Driver.

Hopefully this will help someone else out when they run into this frustration.
