I ordered this power supply for my IBM and was for the good reviews also quite confident, even if it is obviously very low. After the power supply has arrived with me, it had directly convert a loose connection and I had it again. The exchange was also very fast and without problems. However, after just over a week began the thing at one time to smell so funny and then went nothing more. Apparently a short (although I'll have my specially certified by an expert, that the device is also suitable for my laptop respect. Amperage, etc.). The power supply also feels quite cheap at, it is much lighter than the original, which you probably can not be expected at this price. For me, a bad buy. Shall have to look around for a new power supply.
