I have a three year old Thinkpad Edge 11 and with Xubuntu and an SSD it
will manage 3-4 hours, dropping to 2.5 on a 3G data dongle. Lenovo machines
of that generation are quite well known for poor battery life and there are
third party long life battery packs to address the problem. It's worth
doing a little investigation into improving it.
