Not all Asus EEE PC's are created equal. Mine (7" model) also has the memory chips soldered to the motherboard. It may be that other 7" models, or the larger ones which followed are more flexible in their adaptability. A cute little device when I first got it - swept aside by the tablets of today. However some people are still doing interesting things with them. One needs to be be fluent in Linux apparently which rather excludes self.....
Oh yes, the original question from vulcanised ....
Most unusual behaviour. I lean towards implicating a faulty device to start with. If you can advise on the brand name and model, it may allow a comparison with others here who perhaps have the same. (In practise I find that they are all just a little bit different).
My Samsung Galaxy Tab 10 and 7 were both relatively easy to set up, and have been more or less co-operative - given my limitations in coming to understand yet another operating system. (I started with TRSDOS 1.3)
