Thanks - didn't know that. Really interesting. I was surprised to read that they do not put MIMO wireless cards into many of their expensive laptops which just seems cheap and results in potentially slower connectivity. Well, Lenovo are on the not buying list now. All laptop makes have their negatives but Lenovo's negatives are piling up.
If you want to replace certain components in a Lenovo laptops - typically Wifi cards, batteries etc - it has to be on approved list of components from a prescribed manufacturer or it won't work. Some components they specifically block (it's written into the BIOS) even though it would otherwise be compatible.
Thanks - I also almost suggested the Acer 3 dela as the better buy also. What do you mean by hardware whitelists?
Lenovo used to have something called Lenovo Energy Manager on their laptops which allowed you to set different power profiles including the base clock etc. Although there was no direct fan control, a base clock of 0.98GHz wouldn't usually cause the fan to ramp on most normal laptops. Not sure whether it would work on this but it's a thought. That's one reason I wouldn't buy any Lenovo again having owned a Y series gaming laptop and seen some of their other stuff. Quality has seriously gone downhill since the IBM days and there's alot of corner cutting, bugs (numerous BIOS revisions to sort them out, if at all), silly hardware whitelists etc. The Acer Swift 3 for £450 in the other thread is a much better laptop than this.
Does the 720 model have the same fan issue?
