Sharp M4000 WideNote


A poor keyboard hurts the light, wide-screen M4000 notebook.

Lightweight, nice widescreen

Flimsily constructed

Despite its long battery life and easy-to-tote size, the M4000 WideNote disappoints with its poorly executed keyboard.

Sharp M4000


The Sharp M4000 WideNote is a worthy contender in the widescreen, lightweight notebook market, marred by the lack of an intended buyer. This Centrino-based notebook performs right up there with the best of them, and the screen is a pleasure to behold....

Brushed aluminum case; bright screen; minimalistic design

No port covers; no high capacity battery option; no customization options

This Centrino-based notebook performs right up there with the best of them, and the screen is a pleasure to behold.

Sharp M4000 Review (pics, specs)


I recently had the opportunity to review the latest business style notebook offered by Sharp Systems, the Sharp M4000. The new M4000 is listed as an ultraportable laptop aimed mainly for the business population. This laptop is lightweight and highly...

Amazing battery life, arguably the best in its class Innovative power management schemes Gorgeous LCD screen Very lightweight and highly mobile Good overall performance

Poor keyboard build Notebook comes in only one preset configuration No DVD Burner option No firewire port, no s-video out port

The Sharp M4000 notebook is the first laptop I have used by this company. I think it is a very good business style notebook. It runs fast and has amazing battery life. My only major complaints are that for such a stylish notebook, I do wish the...

Sharp M4000 Widenote


On such a light system, we usually see a 12.1-inch or smaller display, which is why this widescreen is such a treat. Even better, the display is transreflective and displays crisp, high-quality video. According to Sharp, it's rated at 300 candelas per...

Ultralight weight. Good battery life. Bright screen

Has only a DVD/CD-RW combo drive. Too few USB ports. No Firewire

Incredibly light for its size, though it needs improvement on features.

Sharp M4000 WideNote


Having done a lot of research on which laptop I wanted to buy, this is the only one that satisfied all my requirements. My requirements were: 1) at least 12" 2) under 4lbs because I wanted portable enough to carry everywhere with me 3) at least 1.7...

Fairly light 3.8lbs, Good performance, Easy access power level button, Good size keyboard, Very sturdy clicks on keys, Very bright crisp display, Strong battery life, Very stylish

Ports are all on side instead of back,Touch pad keys smudge easily,Not as thin as other ultra-portables 1.4"inches thick,no volume control on outside

Sharp M4000 WideNote


I use a thinkpad T42 at work, and decided that I wanted something a little lighter for home. It was down to this Sharp or a Fujitsu S2110. I decided against a Vaio, as I've heard reports of problems from users. I think that the Fujitsu may be a good...

Only 3.8 lb, but with a 13.3" screen; Great battery life; Nice features and casing; Quiet fan

Minor quibbles with the keyboard layout

Sharp M4000 WideNote


My 1st ultra portable was a Sharp MM20. I loved it but needed to upgrade to a unit with more ram and hard drive. I bought a Toshiba R200 and was disappointed. The keyboard was flimsy and the display so dim you couldn't read it when on battery power. ...

Display, keyboard, built-in DVD drive

A little thicker and heavier than my previous laptop

Product Specifications

The M4000 WideNote ultraportable is for the highly mobile individual who always needs a notebook with them, needs the processing power of a desktop, requires a full-size keyboard for easy typing, demands the best possible battery life and doesn't want to get weighed down when traveling. The M4000 WideNote features an exceptionally bright, clear 13.3" WideNote WXGA display from Sharp, the world leader in LCD technology. The Sharp display boasts a brightness of 300 cd/m2 that enables a clear display, even in a well-lit room. Whether you are working on email, a spreadsheet, a presentation, or just kicking back to watch a movie, you are watching on the most advanced LCD manufactured today. The full-size keyboard is a real asset. The M4000 WideNote keyboard, with its 19mm pitch and 2.5mm stroke, is not constrained by compromises, nor will it leave you in any pain, regardless of your hand size. The unique industrial design of the M4000 WideNote offers advanced style and durability. The brushed aluminum outer system housing offers an elegant design, greater impact resistance and increased resistance to dirt and fingerprints. The internal magnesium frames provide superior stability for the motherboard, hard drive, optical drive and LCD display. For enhanced DVD viewing, the M4000 WideNote features sharp-fx, Sharp's exclusive DVD optimization software. This included module works with the included WinDVD software from InterVideo to automatically adjust image contrast for optimum clarity, providing a brighter picture in comparison to the "washed-out" viewing seen on other notebooks.
