I have around 6 Lenovo T500's. A few of them have been flashed with Libre boot and a few have GNU boot. This Laptop is a librebooted laptop with the latest stable version
They're all quad core, the batteries are good, they all have 8gb ddr3 and a 256 SSD.
Some are better quality then others. Brand new cmos batteries, New CPU fan
These laptops come with Trisquel O/S, charger and the CPU/GPU paste has been replaced with new.
This laptop has an issue and for what ever reason the primary battery will not charge up, but i have put a new secondary one in. It lasts about one hour. Under stress test with the CPU at 100percent usage, it lasts 40 minutes.
It comes with a USB 3 see pic
