(1) TravelMate 4740 has NO  m.2 SSD socket. Up to 8GB DDR3 laptop RAM  at 1066MHz  with 64-bit Windows.

(2) Extensa 4630 has NO m.2 SSD socket. Up to 4GB DDR2 laptop RAM at 667MHz

(3) Aspire 5738 has NO m.2 SSD socket. Came in 2 models. Up to 4GB DDR2 laptop RAM at 667MHz.  And up to 8GB DDR3 laptop RAM at 1600MHz.

All models can have 2.5" HDDs which can be replaced with faster 2.5" SSDs. And will accept higher speed RAM but operate at the buss speeds indicated above.
