IBM or Lenovo R60 laptop Here are things I found that might be useful for other laptop users (The IBM access to BIOS options is better then others)
On control panel - click SYSTEM if your running XP you'll see data - the last two lines have the rated CPU speed (T2500 @ 2.00Ghz) and the last line shows speed CPU is running at plus memory If last line doesn't show max CPU speed then the CPU is throttling down T2500 BIOS, I only see the option to modify BIOS on boot up in single screen mode (unhook the 2nd screen) These were items I thought would be of interest: DMA HD - enabled Bluetooth - hidden Serial port - disabled Modem - hidden Parallel port - disabled POWER SCREEN: SPEED STEP TECHNOLOGY -->> MUST BE ENABLED if you do not enable this it defaults to SLOW set the four other speed step technology modes to MAXIMUM PERFORMANCE CPU Power management -->> DISABLED PCI Power management -->> DISABLED Core Multi-Processing -> ENABLED Execution Prevention -> IF PowerSDR won't run - set to Disabled and try again 73 Robert W5AJ ----- Original Message ----- From: "Mark Lunday" <[email protected]> To: "'Mack'" <[email protected]>; "'Ruben Navarro Huedo'" <[email protected]>; "'Tim Ellison'" <[email protected]> Cc: <[email protected]> Sent: Sunday, August 16, 2009 11:02 AM Subject: Re: [Flexradio] Toshiba Satellite U400 (now which laptop) I gave up on my Lenovo T60 and went with a desktop Mark Lunday WD4ELG Hillsborough, NC - FM06kb [email protected] http://wd4elg.net http://wd4elg.blogspot.com -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Mack Sent: Sunday, August 16, 2009 9:44 AM To: Ruben Navarro Huedo; Tim Ellison Cc: [email protected] Subject: Re: [Flexradio] Toshiba Satellite U400 (now which laptop) The only laptop that I've had flawless performance from is the Macintosh MacBook Pro running bootcamp and XP.
