I just bought an AMILO Xa1526. The shop installed two 1024 Mb memory modules (DANE-ELEC DDR2 533 Mhz) and there is no memory error when I test with memtest86. As soon as the notebook is connected to AC power, I'm unable to launch XP, I see the welcome screen and the beginning of the welcome sound and it hangs ! Sometimes, it hangs on the xp logo screen. If I power up on battery, I enter without any problem in XP but if I reconnect to the AC power, I'm sure to have a BSOD few minutes later... I suspect a power management software problem. Any ideas to help me ?
