|Sony support is pretty good, so chances are they're right. You can probably use a hard drive larger than the max. originally available for the model, but you may not be able to get one from Sony, and in any case your mboard main chipset probably is incapable of recognizing a drive larger than 137gb manufacturer's size = 128gb in your bios.|
What operating system are you using, and/or want to upgrade to?
Your computer may not meet the minimum requirements for Vista even with everything upgraded to the max.
- the graphics adapter is probably built into the mboard and is not removable, so you cannot upgrade that.
- the cpu may be soldered into the mboard, not in a socket, and in that case it is not removable, or it is in a socket and removable but you may already have the max. cpu the mboard can support installed.
- you MAY be able to increase the total amount of ram installed, but if you have two modules now, you may have to replace both of them in order to get the max amount of ram.
See response 5 in this for some places where you can find out what will work in your mboard for sure:
You can improve the graphics if you don't mind using an external monitor, or add a TV tuner, or add video capture capabilty, or add a USB 2.0 controller card, etc.
See response 1 in this:
or you can add a better wired or wireless network adapter card (PCMCIA in your case), etc.
You cannot make upgrade the capabilities of the the mboard to make it capable of more than the maximum it is already capable of.
- you cannot make it capable of recognizing hard drives larger than 137gb manufacturer's size = 128gb in your bios and in Windows if the main chipset cannot support that, even if you flash the bios to a newer or the latest available version (at best, any hard drive larger than 128gb will be seen as 128gb by the bios), but you can use what's generically called a software "dynamic overlay" that will allow you to get around that (available free on thedrive manufacturer's web site), or you can get PCMCIA drive controller cards that support using larger directly connected external drives, or you can use an external hard drive of any size connected by USB or firewire, if XP has Sp1 or later updates installed.
- you can't upgrade the max UDMA mode for hard or optical drives the mboard main chipset will support. If you get a hard drive controller PCMCIA card, I know from experience a drive connected to a modern drive controller will be recognized regardless of what size it is, but the drive often cannot run any faster than the mboard's main chipset will let it when the mboard has an older main chipset.
- you can't upgrade the USB 1.0 or USB 1.1 the mboard main chipset supports to make it support USB 2.0, but you can get PCMCIA USB 2.0 controller cards.
If you use an external drive, if you want to be able to boot an operating ststem from it, your bios must support booting from it in your boot order settings. E.g. you must be able to select SCSI for a PCMCIA drive controller card, or USB or firewire or removable drive for a USB or firewire connected external drive.
