Happy new year dear notebook users
Once I wrote about sound issues with the Acer Aspire 7520.
This problem was that touch I brought this notebook to the helpdesk and even there they could do nothing with the problem. Every driver, every setting, every tweak and every maintainance won't work eighter.
How I fix it?
Installing XP on the notebook results in a lock-up of Windows XP during boot up at the thirt boot. Thirt boot? Yes, then Windows XP starts in prefetching mode when it is installed from the ground as I did.
Thus, disabling prefetcher at the very first session and the laptop won't lock up. Strange, but usefull to know.
When I listening music now I hear not any click or plops in the music, not one. Perfect!
But! the first harddisk is in PIO mode only and the noisy harddisk stays at UDMA 5.
resetdma.vbs won't work in any way and I gave it a try to install XP on the second harddisk with DMA enabled and setup processes succesfull, but every driver refuse to install on that second harddisk. Also strange (but now I know now that disc is bad)
So I dissambled that second harddisk and ran resetdma.vbs again. But this time it works and this is 4 days ago and it works still good. The harddisk which is left runs smooth.
Sound issues are gone, but when booting in Vista the sound clicks again, so I've killed Vista hardly.
The sound problems in Vista is not due to the harddisk!, but the application errors where the problem exist is the reason.
And the sound, yes, stick with it until I decide to install XP again without prefetching and at this time prefetcher works fine because the harddisk stays at DMA.
If a disc goes back to PIO mode, prefecter locks up.
Finally, after a very long fought I can enjoy my music again and without any issue. Even during defragging the sounds contunues and in Vista it was unthinkable to defrag and listen at the same time.
In summer 2003 I bought Windows XP home edition full edition and it is his money worth it.
Why Windows Vista fails at that point?!! Until desperation!
In XP the sky is clear and lucky is I am Windows XP is even a lot faster as Vista and especially in games, shutdown and boottime.
All drivers for the 7520 are available.
Misterious sound issues repaired, Aspire 7520
