i have a problem with my XPS15 since receiving it. All is well, but sometimes the charging status LED is blinking with the following pattern:
3 orange, 5 white, 3 orange, 3 white
Does anyone knows what it means? I already had a technician who visited and replaced the motherboard and battery, but the problem is still here.
On top of that, my idle temp is not dropping under 45 celsius, and CPU under load goes over 90 celsius. I'm pretty sure that is not normal, and i believe the technician who replaced the motherboard did a poor job repasting the CPU and GPU with thermal compound.
Can you please share what are your temperatures for this model (9560 i7 7700HQ) ?
I am so glad to finally find someone else with the same issue! I have the same thing. Every couple of times I power on, I get 3 amber, 5 white then after a short pause, 3 amber, 3 white. Then the system won't boot. I haven't found anything like this sequence in the troubleshooting guide. I did the full pre-boot test and everything passed. When the laptop does boot, everything else seems normal.
My temps at idle are around 45-50. I think that's normal. My fans don't speed up at that temp.
I hope someone can figure this led blinking power issue. DELL-Chris M, I know you mean well, but that image isn't related to this problem.
I'm going to monitor this thread in the hope that someone can finally figure this out.
Exactly the same behaviour for my unit.
Nobody i have spoken with at Dell could give me an answer as to why this is still happening after having the MB replaced.
As for the temps they wanted to replace the heatsink and do another application of thermal paste on the CPU and GPU, but i don't think the heatsink has anything to do with it, and i have confirmation from aomeone at Dell that temp of 93 Celsius under load are not normal, or safe for the laptop in the long term.
Yesterday, at their request, i have sent it at the repair center to be inspected and hopefully they will find out what is wrong.
"I know you mean well, but that image isn't related to this problem."
"sometimes the charging status LED is blinking"
To which LED are referring? There are only three on this model =
- power button
- battery charge
- battery gauge
Are you saying that the "3 amber, 5 white then after a short pause, 3 amber, 3 white" are not on one of those LEDs pictured?
I think he meant that the problem here is the battery charge LED, but the behaviour is common to a system error.
Under the picture you attached is just the common behaviour of the LED when everything is working as it should.
Yes, what Marius_V said is correct. It's the battery LED, but it blinks after hitting the power button and before loading the BIOS. When it happens, the boot sequence doesn't happen and you have to hit the power button again.
I think the wording in that chart must be incorrect because the light flashes happen on the battery LED, which seems to be called the power LED sometimes.
The situation is that it does 3 amber, 5 white followed by 3 amber, 3 white. The chart says that the sequence will be repeated, but in this case it's two different sequences. Also, the chart says the blinks can go up to 9, but the chart doesn't have entries for higher than 3/4.
So our/my questions are:
* What does the 3/5 sequence mean?
* Why does the sequence not repeat, but instead shows two different sequences?
Unknown. we cannot replicate the issue on the two XPS 15 9560 in the lab (BIOS 1.3.3, 16GB ram, i7-7700HQ). To validate if this is a trend or if these are two uncommon issues, other XPS15 9560 owners will need to post the same issue, their specific hardware, BIOS revision, etc.
OK, I might have stumbled onto some more info. It seems to happen when powering on from battery only (no AC adapter). It might also need the battery to be really low or empty. I'm still looking into this, but these things seem to lead to the issue.
