Maybe I am not lucky. I have two Lenovo laptops failed in hardware in the
the past two years. The first one is N100 and it was about 3-4 years old.
About half of the keys were not responding. It is hard to find a replacement
. The second one is SL500 and failed just after one year warranty. This one
is quite complete and nothing happened after pushing the power button. Seems
a power supply circuit or mother board problem. It is a 500$ machine but
Lenovo asked for 575 to repair. I will think again about Lenovo if I were
you.
