I’d like to post a problem, concerning my main laptop, a F-S Amilo Pi 2540. Well, after one year of normal use, its battery became dead, (it was my fault, after 2-3 exhaustive discharges). Recently, I replace its original processor (Core Duo T2330) with a faster one, a Core 2 Duo T7100. Also, I obtained a new battery from a third party manufacturer, as long as I didn’t find an original one. While the computer is functioning flawlessly on AC mains, it becomes very slow on battery (processor’s core speed is lowering to some 200, or even 100MHz). As a matter of fact, the laptop becomes so slow, that it is useless. This is happening no matter what power scheme I choose in the Windows Vista control panel. Specifically, even if I set min and max processor energy state to 100%, the problem remains the same, and it persists even on a fresh install of Windows, just like the laptop was new (I tried a fresh install on a spare hard drive). Nonetheless, the operating system (Vista Home Premium) is fully updated, and works fine, when the laptop is connected to AC.
I just made a thought, that something is going on with the battery, an incompatibility or something like that, but I can’t be sure. If somebody has come across such a problem, I would appreciate some clues. Also, please, I’d like some recommendations about what battery should I choose.
(Another, minor problem is that the wired net card has become invisible to the OS, but I don't mind, as the laptop is always connected via its wireless connection. Any way, if somebody has a solution for this, please, let me know).
Thanks for your time guys…
