Keyboard and Touchpad on my laptop stop responding after wake up from sleep status

Im still confuse about this.... when my aspire 4710 wake up from sleep status, the keyboard and mouse stop responding, this is happen in windows XP, Vista Home Premium, and Vista Bussines. I think this can be happen in another version of windows like Vista ultimate or even Vista Home Basic.

When I close the lid, the laptop will sleep, this is default setting on windows vista, and when the laptop wake up, keyboard and touchpad stop responding, but not the mouse... I still able to use it. I tried to restart the laptop, but it cannot boot up again, nothing appears on the screen, even bios. Just LED on power button still on.



I hold down power button for several seconds, to force laptop shutdown. I press the power button again and hope that the laptop will able to boot up again. No.. it can't boot again, until I remove the battery and insert it again.

I send an email to Acer about this, but Acer customer service haven't reply my email. I think there is a BIOS problem (maybe....) by the way, my BIOS version is 1.02

Do you have same problem with me?

Acer Aspire 4520 AMD Vs Acer Aspire 4710 Intel - 3DMark 2001

Do you think every laptop with AMD processor is better in 3D graphics than the Intel ones? maybe yes... maybe no... :)

I try to compare two laptop using 3Dmark2001 for 3D Benchmark:

Aspire 4520 (left) and Aspire 4710(right)

Two Aspire with 3DMark 2001

Aspire 4520-300508AMD Turion™ 64 X2 Mobile Technology TL-56 (1.8GHz, 1 MB L2 cache)
1GB DDR2 memory (upgraded from 512MB)
Nvidia GeForce 7000M



Aspire 4710-4A0512
Intel® Core™ Duo mobile processor T2450 (2MB L2 cache, 2.0GHz, 533MHz FSB)
512MB DDR2 Memory
Intel® Graphics Media Accelerator (GMA) 950



I set up the NVIDIA 7000M with 256MB Graphics Memory and Intel GMA 950 with 224MB

The test was not running on default resolution (1024x768) but running on 1280x800 (widescreen)and see the result here.. (click on the picture to enlarge):

Aspire 4710

Aspire 4520

Maybe if I have more RAM and setting up the NVIDIA 7000M with max memory (896 MB) Aspire 4520 will be the winner...

sorry for my english, Im still learning ;)
