Hi, Recently, I flashed libreboot to my X200s (with L9300 CPU). But it seems that there are some EC problems in X200s, which I haven't found in a X200. 1. With a third party battery, when I put the X200s on dock, it'll shut down. 2. With a third party battery, the battery will not charge, but it can charge on a libreboot X200 or another X200s (with a single core Celeron CPU, not tested on the same X200s) with factory firmware. 3. At last I bought a factory battery, the first two problems will not appear. In these two days, I found that when I charge with a 90W adapter, the CPU will get very hot and the laptop will shut down. It seems that it'll not happen with a 65W adapter. Iru -- Please do not send me Microsoft Office/Apple iWork documents. Send OpenDocument instead! http://fsf.org/campaigns/opendocument/
