The bolt was installed in a Lenovo X121e subnotebook. Installation was resolved quickly and easily, noted there was not much (only one cable had to be pushed to the side carefully, as this extends over the memory slot and should not be crushed - but applies only to the X121e). The store was immediately recognized and works in my Win 7 64-bit with wonderful!
Something I was scared about the current memory prices, I think you should strike, 24 euros for a 4GB DDR3 bars and 16 for a 2GB bar is already NEN Pops.
Clearly, buy!
