I have a laptop, Dell Latitude 120l. Anyone know if the Sims 3 will work, or will i need to replace the video card?

I have a Dell Latitude D610 laptop and the charger that i use doesnt work. It worked about a week ago, but now everytime I plug it in, it doesnt charge, the green light that is on the power unit doesnt light up, and it makes this tiny beeping noise. Anyone know why its not working and how to get it to work?

I just bought an IBM Thinkpad T20 Laptop off the internet but then, when I was reading info on the web about it, someone said that it doesn’t work with pen drives or MP3 players.
Is that the same with all IBM Thinkpad T20 Laptops?
HELP!!!

I have a Dell Latitude and the ram memory says pc133. I tried to buy another piece but it was too expensive. I placed an order online but its different pc2100. Does anyone know if this PC2100 is going to work on my Dell Latitude?

Will the ATI Raedon HD 4650 1GB work on my Sony Vaio desktop (PCV-RS226) which has 512mb ram. I am also plotting to upgrade the ram to 2 GB if the videocard works with my PC.
