|You can find out how large a hard drive you can install by searching the web using your make and model.|
E.g.search the web using:
thinkpad iseries 1400 type 2611 replacement hard drive
thinkpad iseries 1400 replacement hard drive
You can't install a larger ram amount than the main chipset can recognize properly.
See response 5 in this for some info about ram compatibilty, and some places where you can find out what will work in your mboard for sure:
Correction to that:
Once you know which module ID strings (part numbers) work in your mboard, you can get them from anywhere you like that has ram with those ID strings.
If you have brand name ram, it is usually easy to look up whether it's ID string (part number) is in a list of compatible modules found by using your mboard or brand name system model number.
If the ram is generic, that may be difficult or impossible.
To find info about your model....
Look at the label on your laptop.
It has a Type and a Model on it
Type: e.g. 2611
Model: xxx, e.g 1RR

That yields you the home support page for your specific Type and Model
- sometimes the original info has incorrect info about the max ram sizes / total ram you can install (less than it actually is capable of).
- there used to be a limit regarding the max hard drive size you could install because drives that had more than a certain capacity required more power, but that does not apply to new hard drives or fairly recent hard drives.
- if your model is really old (was made before about 2001) then you may not be able to use a hard drive larger than 137gb (128gb binary in the bios and in the Windows operating system in Disk Management) and have the mboard's bios recognize it as it's full size - it will be seen as a 128gb (max) drive in the bios.
