RAM tops out at PC2700. CPU is not easily upgraded, soldered ball socket. Disassembling a 1400 should be avoided if possible, the cable connectors are fragile (particularly), hard drive connector cable motherboard end fragile, frankly not nearly as robust as TC1100 taking apart department.
Best advice is to be EXTREMELY gentle sliding the power switch, it's a bad design that fails by breaking up internally. I would always use taskbar to sleep, hibernate just to off-load cycling that power slider.
Also, like most tablets, but particularly because plug angled, avoid stressing power socket. It's a bear to replace. The power brick is prone to dying, I would order a spare ($25 on eBay - get the neat AC power adapter socket with it).
Because the 1400 has no fan, the CPU will cycle downwards under heat stress (just when you don't want slowdowns). When on AC, I always used a Targus Tornado 12" USB cooler pad ($20 on-line), it fits exactly dimensionally under 1400 and makes HUGE difference running high CPU tasks.
Would you comment on your WD250 drive install, did you use their BIOS updater, partitioned?
