Really? I have a 2013 Latitude and I haven't experienced that yet (or never noticed). I still have the no-name adapter here, so I'll have to check (I only just got a proper 130W).
If that is the case, part of me wants to play Devil's advocate and say that Dell have erred on the side of caution: these no-name adapters really are quite terrifying with thermals, which makes me wonder what wattage they're actually rated for. I was frequently in WTF mode because the adapter block was too hot to keep my hand on. I didn't really have a choice either, as my battery was at like 38% capacity. This official 130W is barely warm under load.
Aside: one thing that really eek'd me out about that no-name adapter is that it has a green LED inside it. The only thing is, you can only (just barely) see it through the slits on the sides because the plastic isn't clipped together properly. The manufacturing quality is atrocious.
Try applying load to the CPU and see what cpuinfo_cur_freq reports. If I boot my ThinkPad W530 (workstation laptop with a large power envelope) with no / dead battery, it will say full speed is available, but it will remain at the minimum speed until the battery is partially charged and I reboot.
