I have an HP Pavillion dv2120us with a stated RAM limit of 2GB, however when I use the Windows help utility to check the installed hardware it says that I have 1GB installed (which is correct) and that the max RAM is 4GB. I've also read before that some dv2120us's while published to have a 2GB limit actually have a 4GB limit. Can I trust the windows help utility and buy 4GBs of ram to upgrade my laptop?

As far as I know, the machine supports 4GB of ram, so you purchase the ram modules from a pc parts dealer and install them inside the machine, removing the existing ram, there are 2 slots, so you need 2, 2GB cards.
You do not require any drivers or bios update.
Windows will need to be upgraded to 64Bit version if you wish to use the full capacity. as normal windows is limited to 3-3.75GB

You are basically limited to what was optional on the model. So you can only upgrade to one of the following cpus:
Intel Pentium M 745 (1.8-GHz) with 400-MHz front side bus (FSB) Intel Pentium M 735 (1.7-GHz) with 400-MHz FSB Intel Pentium M 725 (1.6-GHz) with 400-MHz FSB Intel Pentium M 710 TJ85 (1.4-GHz) with 400-MHz FSB; operates at a lower temperature than other processors Intel Celeron M 340 (1.5-GHz) with 400-MHz FSB Intel Celeron M 330 (1.4-GHz) with 400-MHz FSB
And you are limted to 2gb of ram max on this model.
I think you have a suspect hard drive on your laptop. It is slowly failing. Hopefully you have got the Recovery CD/DVD for it. Not sure what OS you are running. I suppose it will be Vista. You can download disk test utility Seatools from Seagate website and it will give you an indication of the state of your drive. I think this model of HP laptop used a very cheap generic brand disk drive. Best to replace with Seagate or WD of same capacity as your present one. It will be hard to get data back if you do not have backups. Hope this helps.
Well If its windows xp 32bit OS then it only reads 2.5. I run xp x32 bit with 4 gb ram and i only list 2.7gb ram. Its nothing to worry about. Your system is actually using all of you ram even though windows isn't posting all of it.
