[Acer Aspire 1410/1810t/1810tz] Timeline Tweaks (2)

This is because of SuperLFM mode in the CPU. It effectively halves the FSB while idling, in order to reduce power consumption. So the actual performance might be comparable to 800mhz instead, but as soon as you start to use the computer, it switches into the 1.2ghz or 1.4ghz mode.

The core speed says ~ 1600MHz though. What's up with that? It shouldn't exceed 1400MHz?

It's CPU-Z' fault. It's 8x/2=800MHz

Installed Win7 RC x64, and upon completion I found that boot and resume were taking 30secs or more each time. Research indicated that the delay could be a problem with W7 x64 and AHCI settings, so I set the BIOS to use IDE instead. Of course, W7 complained that the disk had some kind of error, so I did a little digging.

At first I set things back to AHCI and installed the latest Intel drivers I could find (Chipset drives, Matrix drives, SATA drivers, etc.)...still had the 30 second delay, and still got errors when I tried to boot with the BIOS set to IDE.

The answer was in the discussions I found about how to enable AHCI *after* installation (originally on XP, but the issue remains on Vista AND W7). Reading these, it dawned on my that the IDE drivers probably hadn't been loaded by W7 once it detected AHCI. And in fact, I learned that you can enable BOTH IDE and AHCI by setting the appropriate registry flags - W7 will load both, and use which-ever matches the way you've set your BIOS.

So...to enable BIOS selection of AHCI or IDE in W7:

1. Exit all Windows-based programs.
2. Click Start, type regedit in the Start Search box, and then press ENTER.
3. If you receive the User Account Control dialog box, click Continue.
4. Locate and then click the following registry subkey:
5. HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Msahci
6. In the right pane, right-click Start in the Name column, and then click Modify.
7. In the Value data box, type 0, and then click OK.
8. HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/PSIIde
9. In the right pane, right-click Start in the Name column, and then click Modify.
10. In the Value data box, type 0, and then click OK.
11. On the File menu, click Exit to close Registry Editor.
12. Reboot, F2 to Setup, and select your preferred drive interface...

I don't know if I've sacrificed anything important by using IDE instead of AHCI. The system still feels as fast as ever (I'm using 4GB of matched PC800 dual-channel DIMMs), and I haven't seen any other errors. In any event, I won't switch back to ACHI until a) they fix the 30-second delay problem and b) there's compelling value over using IDE.

That said, I have an Intel 160GB X25M (gen 2) on the way for this puppy...I may try both ways once I get that thing installed.

FWIW - the referenced Atheros drivers are the same ones you'll get automatically when you install Windows 7 x64.

Or at least, when I told W7 x64 to look for an updated Atheros driver, it installed these exact same drivers.

Has anyone else had issues with their laptops waking up from sleep by themselves? (Quickly and consistently.)

Started happening to me lately - although I don't remember changing anything. Maybe running windows update.

In my case, using windows 7 - x64. Running 'powercfg lastwake' claims that it was woken by the power button. Anyone else? Ideas?

That's interesting. I first installed on my first SSD with IDE mode. But then with my 2nd SSD I converted to AHCI mode by editing the registry. It does seem slower now that you mention it. I'm running Win7 X64. I'll flip the BIOS back to IDE to see if there's a difference in performance.

If Acer uses the same numbering scheme as Intel, then it looks like Acer has a newer wireless driver. 12.5.0.57 added on 2009/09/10.

I tried to install that driver from the Acer site and it killed my wireless. I had to download a driver from intel to get it back up and working again.

While it didn't kill my wireless, when I tried to install it, it just never updated my driver. I still had the old Acer one. I downloaded the latest from Intel, and it worked fine.

Does anybody here know if any Touch Screen mods are available for this?
