From: Blue Streak on 14 Jan 2008 11:07 Hi, folks! The other day I picked up a new laptop. I have no programs that are compatible with Vista so I downgraded it to XP. I'm still hunting for all the drivers ... but that's not my question! I have noticed with utilities like CPU-Z that the CPU clock is not throttled down when it is running on batteries. The CPU is still blazing along at full speed sucking the life out of the battery. I was lucky to get 90 minutes out of it! My question is why isn't it automatically throttling down like my old laptop? What can I do to get it to throttle down while running on batteries? TIA... Hardware specs: - Turion 64 x2 TL-50 (1.6 GHz, "Taylor" core) - 120 GB hard drive (SATA) - 2 GB of memory - Atheros WiFi card, LAN, modem, etc.

If there is not you will need the acer power management app, which lets you set custom power profiles. It should be on Acer's website, I recommend you download and archive everything you can get from their site, though this app "might" also be on one of the CDs they sent to you. Check out their FTP offerings too, ftp://ftp.support.acer-euro.com/notebook/aspire_5100/ (note if yours is model # 51nn like 5110 instead of 5100 you might need to go up one directroy to see other files). I believe this might be what you want: ftp://ftp.support.acer-euro.com/notebook/aspire_5100/utilities/Acer ePowerManagement 2.0.2016a.zip though the spaces in the file name broke it so here's a TinyURL link to it: http://tinyurl.com/yweg9r Once installed there will be a battery or some other little icon in the Taskbar tray you open to configure the power settings.
From: AdenOne on 14 Jan 2008 16:48 Go to power management on the screen saver page, and choose mobile \ battery from the list of profiles. This should enable full speedstep \ cool n quiet technology and backstep the core speed. Interesting, you say you had NO Vista capable programs? Vista will extend battery life by 15-25% over XP usually. If all else fails, try to get a utility from the laptop manufacturer.

Further one does not want to continually have to switch this back and forth. > >Interesting, you say you had NO Vista capable programs? Vista will >extend battery life by 15-25% over XP usually. Umm, no Vista does not usually save battery power it usually uses more unless you use manual or automated methods to reduce the GUI effects, at which point it only uses a little more instead of a lot more.

I get an extra 45 minutes when using Vista Ultimate instead of XP Professional, with the Vista power management options having a lot more scope than the simple XP ones. Backlighting and unused features are usually controlled via a third- party or manufacturer application, not directly via Windows. Unfortunately when you wipe a laptop and install older operating systems, you lose all of the manufacturer specific apps, most of which are useless, granted, but some are necessary for power management. |
