[Kernel-packages] [Bug 1726159] Re: PCIe BUS Error causing really slow laptop performance

I fixed the slow booting problem by editing "/etc/hdparm.conf" and changing "apm_battery" value to "255". Now my laptop boots normally on battery mode (same speed as plugged in AC). Now, for the AER problem, just ignore it. Add pci=noaer as kernel boot parameter. I hope I helped. -- You

I face the same issue on my HP ProBook 440 G4. And my laptop has the same crappy RTL8723BE WiFi chip. But the PCIe Bus Error and Wifi problems you might be facing are separate issues. The PCI bus errors can be cured by adding pci=noaer to the kernel args as mentioned by many users in the thread

Very Important Info: I inserted my Samsung 850 EVO 250GB SSD on my laptop's HDD slot and on battery power, with TLP off, it runs on normal speed 550MB/S Read/Write! My primary M.2 SSD "Micron 1100 250GB" is still running on 32MB/S Read/Write. That means Micron SSD is checking for battery/ac mode.
