I have a Tecra A4 PTA42U-0200012l with a Pentium M processor at 1.73GHz, 2GB RAM, running 32-bit Windows 7 Home Premium SP1 on an SSD. It works very well, loads fast, proccesses decently, but the display is weak. Can the graphics card (Intel 915GM/GMS,910GML Express Chipset Family[Toshiba] be replaced with a better one?
