My father bought a new notebook two days ago (Fujitsu/Siemens Amilo M1450G) and he has huge problems with it every second time after he was surfing the net.
The Notebook is running on WinXP and he is using an Acer ISDN 128 Surf Mini USB modem to get online. Every second or third time when he was online and when he is disconnecting, the computer screen turns either blue and a message like "Severe Error" (in German: "Schwerer Ausnahmefehler") appears or the usual Win desktop shows up but you can't do anything anymore, i.e. the mouse doesn't work anymore and you can't switch the notebook off anymore (to switch it off you have to disconnect the battery). When you start Windows again after this, a small pop-up appears which says something like: "Capi Error", so I guess it has something to do with the ISDN connection.
As I already wrote, the error doesn't occur every time when he is disconnecting from the internet but every second or third time. The modem itself doesn't give an error message.
Does anyone know what is going on? I never saw that before on any computer.
Thanks in advance for any help or tips!
