XPS user here, I really love this laptop (L502x) but I will "never" buy Dell laptops again.

Because, this laptop is 4 or 5 years old (work like charm) but the problem with all Dell laptop models are, their adapter has worst quality ever. Simply, Dell adapters are not built to last long.

When Dell adapter is broken (a.k.a the chip inside doesn't send signal that it's genuine one) Dell laptop stops charging the battery, shows annoying adapter not recognized message.

And most annoyingly it drops CPU speed, I have Sandybridge 2630QM cpu i7 with 2.5 Ghz but failing adapter makes it speed 900 Mhz and it doesn't get any faster. IF you plug out the adapter then it turns back to normal but putting back on "not recognized" adapter causes the same issue.

So simply, Dell kills your laptop completely if the adapter is broken. So now I either have to buy a new laptop or find a used adapter to replace my current 4 year one.

The XPS 13 with USB-C (current and previous generations) at least can charge via USB-C, so you can ignore the Dell adapter if you wanted.
