It may require either or both of these, since I can't see the laptop, I'll give you both, first and easiest, is go into the bios, and look in the system settings, see if the memory/ram is set to auto it may be set to a specific amount or speed, f 10 your way out and save the settings, hopefully that will fix the problem, if not then unplug and remove the battary, open the base and remove the little cmos battery looks like a coin, wait 5 min and replace, that is where your settings are saved when the machine is unplugged. Restart after putting everything together, then you may have to go and enable your custom settings, but the memory should show the new stick you installed, If not it's possible you have a bad stick, it won't be the first time, good luck
There is nothing wrong and your install is OK.
The laptop has used some of the RAM as video RAM for the video card that is part of the motherboard.
You should have noticed that with a single 512Mb RAM you would not have the full 512Mb RAM available to you, the video has grabbed 128Mb of RAM.
there are two parameters that control the cpu speed, one is fsb and the other is the frecuency of ram, make sure your cpu supports what you have and i dont remember where exactly are the options in the bios, but i had the same motherboard and i know they are arroun there just make sure to select 200 mhz for your memory if it is 400 mhz ok? and then make sure cpu supports fsb 400 so your fsb must be 400 in the bios... if you change somethings in the bios and after saving changes and rebooting the motherboard does not respond you just have to take the lithium battery off for 5 minutes and disconnect power cables or move the cmos jumper to reset position and you will be back in zero to keep trying, you cannot damage anything by just trying, but never try to give more tension to ram or any part.
The BIOS recognizes the same speed chip. Say, "PNY 512mb 333mhz 12ns". If you mix and mismatch, the BIOS won't see it even though your motherboard will take the differant type chips.
They should all be the same.
