You'll find some useful powersaving profile like the lifetime extend mode, wich set the ldc brightness at lowest setting, disable optical drive, and so on....

 

i also get all those power options when i click on the battery icon in the system tray and click "more power options"

 

Ah i see, the word "Enhanced Power & Performance" itself is not the name of one power plan, it refers to the whole power management system. I normally use MS control panel, the plans are the same as shown in Dell program but without colour graph.

 

I've had both and ended up returning the IPS panel due to poor mid brightness flicker (never got a chance to try the A04 BIOS )

Although the IPS panel has retina-searing colour intensity, I don't think its sequential RGB backlight is as gentle on the eyes for general text reading as the WLED because of the inherent high frequency colour shifts.

In the WLED, the white light emitted by the backlight is filtered physically by R, G and B colour filters over each 1/3 subpixel. With the RGB panel, the whole pixel shows first then R, then the G, then B, with the backlight switching colour in sync with the pixels. Essentially you're seeing a pure red, then pure green, then pure blue image, but switched fast enough to fool the brain (200Hz+). Filtering is temporal, rather than spatial.

Try reading white text on a black background on the RGB display, and you get the rainbow effect common to most DLP projectors if you move your eyes about.

Also, technologies such as ClearType have been heavily optimized for the RGB subpixel arrangement of traditional LCDs, that I think simply doesn't hold on these sequential RGB panels.

Bottom line: if you want great colour, go IPS RGB. If you want sharp, natural looking text, go WLED.

 

Do you know the manufacturer and model of the IPS screen you have/had??

 

Thanks for the info. All check into that, too bad we can't get 4gb

 

I've been reading up on the Certification MIL-STD-810G for the M4600 and am especially interested in any field tests any of you may have conducted.

One of the uses I have for my laptop is when I perform on it out in the wilds of the Southern California desert (I'm a DJ/performer). The daytime temperatures are often in the 90s F, sometimes accompanied by 20-40 mph winds; or, in the wintertime at night, down to the 30s-40s F. My previous laptop, the Precision M6300, was not especially equipped for such conditions, and during the 2 years I leased it, I had to replace the video card, power supply (twice) and hard drive. (Thank goodness for Complete Care warranty!) It heartens me to read what the Certification MIL-STD-810G implies.

I'll be heading out to the desert soon to take my new ride for a spin, and wondered if anyone else here uses their laptop under challenging weather conditions who can offer any anecdotal evidence.

Precision M4600, Core-i7 2720M 2.20GHz, 8GB DDR3-1333 RAM, 128GB SSD Boot Drive, 500GB SATA 2nd Drive, NVIDIA Quadro 1000M, 1366 x 768 LED screen, Win7 Pro 64-bit

 

Correction again: I'm getting 4+ Mbits/sec on the LAN connection to the router; wireless speed is up to 300 Mbits/sec. Wireless is never going to be as fast as hard-wired, at least with current technology.

300 Mb/s is "Advanced" standard. "Ultimate" is 450 Mb/s, but you need to have the Ultimate card on your computer, as well as a router which can make that speed.

 

You have the 1366x768 screen, could you run HWInfo and post a screenshot of the window with the tab "Monitor" opened? I want to see if they use the same screen as in the E6520.

Do SSD drives require the ST Microelectronics driver?
