Presario 2100US with D-LinkG650 CarBus Fine on AC, Freezes on Battery
Posted on 2005-03-19
I have a used Presario 2100US with 1.6ghz AMD Athlon processor running Windows XP Home SP2 with all updates, 512 MB RAM and a D-Link DWL-G650 wireless card. The card works fine on AC power, but the laptop freezes-- no response to any key including ctrl-alt-del-- when the card is sending/receiving data on battery power. I've done everything that D-Link and HP have suggested including recalibrating the battery, updating all drivers, updating the BIOS, setting different power levels on the adapter, reinstalling ACPI, starting without any services or other starup applications running, using the D-Link utility, using Windows Zero Configuration, using Atheros drivers and utility, etc.. I've even tried two fresh operating system installs-- one with XP Pro instead of Home. All of this has been fruitless.
Is this repairable hardware failure, a glitch with the card (i.e., Linksys or another competitor would have a high chance of working), or a irreparable design failure (i.e., AMD processors in Preario 2100s weren't made for wireless G)? How can (can I?) get this working without an expensive trip to the repair folk? I have the option of returning by mail to the company I purchased it from if I act soon, and they said they would test/repair it, but they are not exactly top-quality professionals and I don't want to risk my investment if I don't have to.
