Can confirm. Have the Precision 5510. With the 4.4 kernel, it more or less works fine. Last I checked, I was getting ~5hrs on battery. Which is pretty shit-hot

Can confirm. Have the Precision 5510. With the 4.4 kernel, it more or less works fine. Last I checked, I was getting ~5hrs on battery. Which is pretty shit-hot for a linux laptop. One gripe so far: Since I updated the BIOS, the entire thing performs like a Netbook-Hype-era Atom CPU when there's no AC power.
