I buy second hand old laptop machines to load as Linux experimental units and most were abandoned due to heat shut down problems in Windows due to dust clogging exchangers /fans etc. Cleaning makes them useable. However old laptops due RAM limits do not like many services at once and especially graphics cards and the linux swop system seems to place more loads (read /write) that the windows page system.
2. Use a 'light' windows manager such as LPDE or XFCE or Enlightenment.
3. Use OpenSUSE with XFCE windows manager.
