Adding pcie_aspm = force to my grub file made my battery to fail soon
after
3-4 weeks i made change in it and from today morning i am getting theit
problem of overheating in my HP Pavilion Dm4 model laptop. What could be
the reason for this. When i boot into windows and check battery status
says ("Consider Changing your battery") and overheating continues in
Windows too... This is really a serious problem now with modern kernels.
Any solutions? or suggestions?
Instead of using pcie_aspm=force you can upgrade to latest kernel (git) as
patches to solve this pcie power management solution is added there. You

" There's just too many hardware devices that don't properly support the
ASPM power-saving modes." and i think mine is one of them. So added this
line caused my hardware to struck with overheating.
