How much RAM is installed on these two laptops? Both share RAM between system and video, and shipped with 512MB, while minimum in published system requirements (for both 13.1 and TW) is 1GB.
I can not download the files from https://yadi.sk/d/ahfNZaod3SU7Ly and I do not like all kind of view scripts etc. too much. Anyhow I had a look at dmesg.txt using the viewer and see these warnings:

Not sure what is the CPU warning about but for the ACPI warnings you could try to disable ACPI in the BIOS.
