17r3 DC-IN cable temperature

I would like somebody to run a little test for me if anybody could be so kind.

Take the base plate off and If you have a laser temperature probe, point it to were the DC-IN and battery cable heads are and check the temperatures while the laptop is running a game.

Due to recent issues with my PSU adapter in another thread http://forum.notebookreview.com/threads/aw17-r3-240w-psu-problems.792370/
I decided to investigate and found out my DC-IN and battery cable are reaching a temperature of over 110c when the laptop is under load.

Surely this cannot be right?

 

I wish i had something to measure the temperatures with. This makes me worried. I havent came across issues like you desbribed though.

 

Does the underneath of yours get hot to the touch where the bottom panel is after it has been on a while?

If so it could be getting similar temperatures to mine inside.

 

It does get hot under load on the bottom. But isnt that the heat from the components? Because near that location is also the heatsink.

too much to me ... try to put electrical tape on it, and use thermal pads above your ram, this could help to solve the problem. can be that the hybrid BIOS is using too much energy from the battery, flash your BIOS again.

 

What is exactly right... Have these newest AW Echo models Hybrid functionality or not?

 

It shouldnt have it since the psu if more than sufficient. But are the dc in cables too thin and thus become too hot or is it a one off problem of a widespread wrongly manufacturered cable or connector that now works with too much resistance and thus heating up.

 

In other words... Yet another new engineering blunder by Dell's engineers? This should not be possible today.

And No one can guarantee whether Dell's engineers have put in some form of hybrid functionality in latest AW models or not... NONE CAN BE 100% SURE ON THIS!!

 

You posted thi sbefore and I said it is an one off thing there. Because the 15R2 which has the exact same motherboard doesnt have these issues. All laptops by the way have battery draining when the power supply isnt sufficient. BUt did they have a faulty PSU? Faulty motherboard? Faulty DC cable?

These kind of manufacturings errors happen in all products for all brands. But is it a design error? Who know

 

Yeah... No one knows what Dell's engineers prefer / do. No one can with 100% certainty that bios / Ec contain some form of restriction or hybrid functionality. Either through their firmware or hard-coded on the motherboard. Selecting the correct cable thickness and the like should have been child's play for an engineer. Dell's engineers huge mistake on the first echo model is a big warning that something is not as it should... But as you said... Who know.

 

This might just be a fault in my system and not everybody's.
That's why I posted to see if anyone else has similar temperatures then we would know if it was more widespread or not.
I have unplugged the battery cable and tested it again with the same results.

I'm getting the cable replaced next week so I will check the new one under load while the tech guy is here.

 

Thanks for going trough that effort. It might be okay that those cables get that hot. But still. I wish Dell could clarify this.

Mine is literally searing hot on the bottom panel right about where the DC-IN cable is when under load.
In fact, it has got so hot at one point that the plastic panel door has started to bubble outward a little bit in one spot.

 

Well, I have had the tech replace the board and DC/in cable and now it is all working well again.
The cable is not that hot anymore (60c ish) under the same load as the last one after an hour. (Instead of 115c as was before!)

The new board came with 1.2.3 so I will not be upgrading to the latest BIOS in the hopes that it lasts a bit longer than a month this time around.

 

Good to hear it has been fixed. Also good to hear it was an one off issue.
