Thanks for all the info! I bought my battery from some random seller on eBay and it was disappointing initially but seems better after a few cycles. I may check out your recommended ones anyway. I did many of the other recommended upgrades already, including replacing the thermal paste, the WiFi adapter and upgrading to 16gb of Patriot Viper RAM and an SSD. I'm very happy with my current setup thanks to you and others. One question I have is regarding boot time for 4.0. Is it several minutes long for you on coreboot/Qubes 4.0? I also get a Failed to Load Kernel Modules message early on in Qubes boot if that matters. Once it's up and running, things run smoothly. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
