PC4200 DDR2 is what this laptop takes. You're wasting money if you buy faster RAM.
I used the Windows BIOS flasher for 1.19 and the touchpad is much improved, it rarely quits responding. Before the 1.19 update there were a couple of times I had to reboot to get the pad to work again.
You must have the AC adapter plugged in to run the Windows BIOS update. It won't do the update if it's not.
Turning off tapping plus the BIOS update made a big difference. I wonder why Acer doesn't show that update on their website?
If you want to use Media Player for DVD's there's a hack for that but then you won't have DVD sound. The free fix for that is www.ac3filter.net
Then you can uninstall Acer Arcade.
Another great whack of room can be had by uninstalling Acer Game Zone. Unfortunately you have to uninstall each game individually, then delete the stuff in the Start menu manually- followed by the Acer Game Zone folders under Program Files.
After that, get the free CrapCleaner from www.ccleaner.com
to clean all the stuff left behind after uninstalling Norton and all that other stuff.
I set mine to all Classic mode so it looks like XP or 2000. MUCH FASTER without the eye candy.
P.S. AVG free.grisoft.com and Spybot Search and Destroy www.spybot.info
together are better than Norton and Windows Defender, they're faster and put far less load on the CPU. After installing Spybot, skip the update and immunize during setup. Then go to its icon in the Start menu, rightclick it then click Run as Administrator. You only need to do that once. Then run Spybot and update and immunize.
To stop Windows Defender, click Start > Run then enter msconfig
With that you can stop Defender, Acrobat, Acer Registration and several other things that slow your PC down and use up lots of RAM.
