Hi Lucie,
I hope the new motherboard will fix your issue.
And yes, it is a batch 8 machine. It could be an issue with the batch but with only two occurences it may be just coincidence.
I had a USB hub die while being used with this laptop and I’m pretty sure THAT is coincidence and nothing more.
Two other hubs I tried work just fine but I don’t keep any permanently connected and so far I never charged through any of them just to keep things simple for testing.
Then there is the BIOS: it appears there are problems with 3.05 and a new beta version will be released.
We also don’t know what is considered normal for these laptops in terms of load and temperature.
It would be nice to have an official test that would load the CPUs in a deterministic way and provide a temperature curve for that case.
I’m tempted to use Prime95 and do a stress test.
And here’s more weirdness. The official power adapter is 60W.
I used three brand new Anker rated 65W, 67W and 70W chargers with different cables and both of them get too hot to touch in the scenario below. Two of them are GaN so they are more efficient than the others.
The cable end entering the laptop is cool but the end connected to the charger and the charger itself gets really hot.
Looking at voltages and currents they all seeem to see very similar numbers but they do fluctuate for any given combination of cable+charger.
What power rating does your charger have and how hot does it get while charging a laptop already warm from normal use?
Do you have any numbers for the high temperatures you see?
Thanks
