Hello all,
sorry for my bad English.
I have a Latitude D820 with T7200 2Ghz cpu, 2 Gb ram and Intel 945 gfx.
I have upgraded from winXp to window7/10 and the cpu now works only at 0.96Ghz. I have changed the system bios from A7 to A10 version but same problem .... laptop works in half speed and it's very slooly.
I read to Dell website that this laptop isn't compatible with Windows7/Windows 10. I've tryed to reinstall from scrath Windows XP but the problem persist ... now the cpu works only at 0.98Ghz.
Have you an idea how to solve this? ... no problem for me working with windowsXP or Windows7 the most important thing is working at 2Ghz.
Many thanks in advance.
Ciao Wizzy
