The memory came well packaged, seems okay to be (has been in operation for only a few days), and the 2GB provide many places for a felt smoother execution (original equipment is 1GB, which eg significantly in some open Firefox Tabs brakes). Sometimes waking works from sleep mode no longer reliable, though some programs are open: the graphic representation is completely distorted, and the computer only responds to long power pressure (to turn); other keys or mouse seem function. After the reboot, but everything is okay again. I can not say whether this behavior has to do with the new store. No matter if you know it, (open documents before hibernation eg store) you can set it, and the performance gain is to me still worth. But the service instructions is restricted to a small piece of paper copied, on which the position of the cover flap to recognize, plus the note to change after the memory changes to the BIOS to "login" the memory. Better instructions can be found in abundance on the internet, and without any plan you should hopefully not anyway make a memory change. So any old matching RAM module does just as well for this conversion, and may be cheaper.
