Question about IBM ThinkPad R52 Notebook
I am trying to install some ram into my thinkpad. I already have the 512 that came with the system, and it supposed handle up 2028 megs (or somewhere in that area).
The ram i bought is 1 GB 200pin DDR2 sodimm - which according to specs should be more than compatible with my system.
When I install the ram and turn on the computer, i hear a series of beeps (like 1-2-3 (pause) 1-2-3), then the screen stay blank and nothing happens from there, I remove the new ram and everything starts up fine. I have tried this multiple times, defragging before installing, disk cleanup, running virus/spyware scan etc... but to no avail.
Oh, I'm running windows XP home edition.
You have the wrong memory chip. The beep code you hear indicates that there is no memory or incompatible memory. The memory you need is PC4200, Which is a 533mhz chip. Memory has a frequency rating that is matched to the processor and motherboard. Not just any DDR 200 pin memory that fits will work, the frequency has to match or it won't work. The new chip should be labeled, make sure it reads PC4200 or 533mhz, if it reads anything else it's the wrong chip. If it is the right frequency chip, then you may have a bad memory slot, the chip is bad, or mislabeled. Here's a link to a memory configurator that gives the memory specs for your machine.

It is OK to mix chip (SODIMM) capacities in the 2 slots in your notebook.
The best system performance will be when you have 2 x 512MB but for now if you install 1 x 512MB, you could even leave the old chip in the other slot, it'll be fine.
