I just did a clean install of Windows 7 professional 32 BIT!!! OEM and the installation went well. Now that I have it installed my battery life lowered from probably 3 hours power saver - 1 hour powersaver (no aero)??? My Laptop Specs: XPS M 1330 Intel(R) Core(TM)2 Duo CPU T9500 @ 2.60GHz, 2601 Mhz, 2 Core(s), 2 Logical Processor(s) Windows 7 OEM Professional 32 bit 4.00 GB Ram NVIDIA GeForce 8400M GS Need help
Why do you have 32 bit if you have 4 gigs of ram?

Weird, I got about 30min extra switching from vista to 7. Make sure that you have all the proper drivers installed(even if everything seems to work, check device manager) and reset the power settings to default. EDIT: Also, get 64bit.
Disable background tasks such as Search Indexer, Autodefrag and Superfetch. Doing this increased my lifetime drastically, because Windows now doesn't do shit when I'm not working on the Laptop (such as making the HDD work all the time - because of upper services). Also, make sure your CPU is clocking down when in idle. Use CPU-Z for this. Core Speed should be below the speed you see, when you press WIN-PAUSE. If it's the exact same, you need to enable powersaving for your laptop (which actually should be enabled by default).

No. It can only [b]see[/b] 4GB of RAM. It can't utilise it. [quote]The 4GB limit is hardware-based - the x86 architecture can really only address memory addresses at 2^32, or 4,294,967,296 (4,294,967,296/1024x1024=4096, or 4GB). So, no executable code can be at any address higher than the 4GB "boundary".[/quote]
I got 2 extra hours of battery life on mine.
You haven't installed the [url=http://support.euro.dell.com/support/downloads/download.aspx?c=uk&l=en&s=gen&releaseid=R153997&SystemID=XPS_M1330&servicetag=&os=WLH&osl=en&deviceid=1134&devlib=0&typecnt=0&vercnt=1&catid=-1&impid=-1&formatcnt=1&libid=27&typeid=-1&dateid=-1&formatid=-1&fileid=205326]power management driver[/url] for your processor so its running at full speed constantly, draining your battery. [editline]04:58PM[/editline] That download only extracts the driver to C:\DELL\DRIVERS\R153997. You have to go into the folder and run setup.exe to actually install the driver.

[QUOTE=Diaklu;18061386]No. It can only [b]see[/b] 4GB of RAM. It can't utilise it.[/QUOTE] The 4GB on 32bit limit is a Windows thing. OS which are able to use PAE (Physical Address Extension) can see more than 4 GB on 32 bit. Since this does not count for Windows (for whatever reasen - Most probably marketing = pushing people to 64bit which is totally ok), you need to use a 64 bit OS.
Windows Server supports PAE. It's no substitute for a 64-bit OS though.
try fooling around with advanced power options
