PL2 too high?

[Gat Pelsinger]

So earlier I was posting threads about an HP EliteBook G5 that my sister bought refurbished which was having problems and crashed every time randomly. A solution I came up with was to disable turbo boost and now the system did not crash.

 

But today, I just found out with a lot of troubleshooting that the real problem was the 45 watts PL2. It could never handle it. Using ThrottleStop I lowered it to around 31 watts and now it doesn't crash. I was shocked to see that the PL2 was set to 45 watts. 45 watts isn't a big number but it is a U-series processor. Or maybe I am just hyped because my laptop isn't that premium and it has a PL2 of 30 watts. Is 45 watts correct? Or was it changed, because it is a refurbished laptop? Also, I was also very curious in how it handled the temps. Even on 30 watts or more it didn't go above 90 C (or at least, that quickly), but my laptop's processor immediately thermal throttles after reaching PL2. The noise of the fans is also very minimal, compared to my laptop's fans who sound like a jet taking off (literally). I saw a teardown video, and that laptop's cooling solution doesn't seem much different from mine. Can somebody explain? And oh yes, is 45 watts normal on a U-series premium laptop?

Vendors can configure their PL1/PL2 to whatever they want, really. Lenovo by default caps the 1315U in my laptop to 15 watts which quite frankly makes it absurdly slow albeit very cool, but with ThrottleStop I let it suck down as much as it wants all the time on wall power (usually around 35-40W).

35-40 all the time or just turbo? Also, how were you able to go beyond the spec?

All the time on wall, and 25w max on battery. ThrottleStop lets you adjust the max power limits and after that it's just a guessing game for if your machine will support it.
