Windows begs utterly for an upgrade on my Dell Inspiron 2330 and I thought that everybody should get a second chance. A short look at the Dell support page stated the full compatibility with Windows 10 – so I should be happy with an upgrade. Again, after hours the machine restarted, I saw the desktop and finally the INTERNAL_POWER_ERROR was gone. But I wasn’t happy. The Inspiron has two internal graphic options – either it could run on Intels HD or it could use as second option an ATI Radeon graphic card. Windows 8.1 was able to (automatically) switch between, the new Windows 10 was not. Maybe I forgot to install Dells driver package? No! Maybe I should use the original ATI drivers? Didn’t work too. The MS fallback driver? Again, same result.
