Microsoft CEO Steve Ballmer kicked off the 2009 International Consumer Electronics Show on Wednesday with an impassioned endorsement of PCs and a sneak peek at the company’s future Windows 7 operating system.

?As expected, Ballmer announced that Microsoft is releasing a beta version of Windows 7, which will be available for download beginning Friday. The news suggests the world’s largest software maker may be giving up efforts to rehabilitate its often-maligned Vista operating system, which was released worldwide in January 2007.

“We are on track to deliver the best version of Windows ever,” Ballmer told an audience of several thousand tech professionals and journalists inside a cavernous ballroom at the Venetian hotel. “We’re working hard to get it right and get it ready.”

Without mentioning the security and compatibility issues that have dogged Vista, Ballmer promised that Windows 7 will make PCs faster and easier to use. He didn’t offer a timetable for its official release, although Windows Vista went on sale more than two years after it was issued in beta form.

?The forthcoming operating system will have touch-screen capability, side-by-side windows for comparison shopping and a “Peek” feature that makes open windows transparent, allowing users to see the icons on their desktop.

“Windows 7 makes it easier to move between the things on your laptop battery ,” said Microsoft group project manager Charlotte Jones, who gave a brief demonstration of the system on the hall’s giant display screens. Jones said the new system also makes it easier to send files back and forth between Home computers.

Ballmer later yielded the stage to Robbie Bach, president of Microsoft’s entertainment and devices division, who praised the explosive growth of the company’s Xbox Live online gaming community. Bach also announced forthcoming releases of new versions of Microsoft’s popular “Halo” game series: “Halo Wars,” due Feb. 28, and “Halo 3: ODST,” which will ship in the fall. Video

?Wednesday’s address marked the energetic Ballmer’s debut as CES keynote pitchman, a job that had been handled for the past decade by Microsoft chairman and industry pioneer Bill Gates. Ballmer’s presentation came two days after a similar, high-profile keynote at the Macworld show in San Francisco by Apple, Microsoft’s chief rival, and its vice president Philip Schiller, filling in for the ailing Steve Jobs.

Unlike Schiller, Ballmer tackled the struggling economy head-on in his remarks. He said that although the recession has created “a period of reduced expectations,” the tech companies that push forward now with innovative research will fare better in the long-term than the companies that scale back.

Ballmer said the convergence of screens on computers, TVs and mobile phones is revolutionizing how people communicate with each other.

“Our digital lives will continue to get richer. There’s really no turning back from the connected world,” he said. “We’re on the verge of the kind of technological transformation that only happens once every 10 or 15 years.”

?As if to prove his point, Ballmer also welcomed onstage program manager Janet Galore, who gave brief demos of some Microsoft product prototypes, including a tabletop-like touch screen and a flexible, wafer-thin digital screen you can roll up like a piece of paper.

In a gentle swipe at Apple, which has gained market share against Microsoft in recent years, Ballmer said the PC remains the best choice for consumers seeking “value and power” in a computer.

“That’s why we say, ‘I’m a PC and proud of it!” he bellowed — a reference to a new Microsoft ad campaign that play off similar ads by Apple.

?Ballmer also announced that Microsoft has formed a partnership with Verizon Wireless to add Live Search tools to all Verizon smart phones in the U.S.

He also announced a partnership with Dell, which will soon come loaded with Microsoft’s Windows Live suite of software, and links between Windows Live and the social-networking site,dell 6y270 .

Reaction to the 90-minute presentation, which also included a performance by Australian musical-comedy trio Tripod, was mixed. Attendees praised the lively pace of Ballmer’s talk, but wished he had made more news.

“I really loved what I heard tonight. There’s definitely a lot of things to look forward to,” said Sebastian Mineau, a Montreal-based blogger with MSN Canada. “It [Windows 7] wasn’t a big surprise. But it was still nice to get the confirmation straight from the lion’s mouth.”

“It was very disappointing,” said Ben Sillis, a reporter with ElectricPig, a British tech site. “CES is supposed to be about new products, new stuff. And this had all already been leaked. There was nothing new.”

Some 2,700 exhibitors and 130,000 attendees are in Las Vegas for CES, the nation’s largest consumer dell c1295 trade show. The event runs through Sunday.

Motherboard battery failure

The laptop battery is dead motherboard cause of computer failure can not be started, see dell battery.

A telephone rings, I awakened from a dream that a friend’s computer problem: press the power button, the computer and nothing happens repeatedly press the power switch is still invalid. After my initial analysis, is likely to be part of the problem of power is not enough power (power of low-grade “patent”) is a short-circuit switch, Collect a variety of tools for a pretty good idea after a friend went straight home.

Indeed, such as friends above, no matter how pressing the power switch (socket and verify that there is good access to electricity), the computer just like wood, like the “one drop of a hat.” Computer does not have any alarm sound, the motherboard does not seem to load the required voltage, power supply fan is not moving, it appears that the computer simply will not be able to power up. Open the chassis closer look at the motherboard and power supply connections and there is nothing abnormal, the power switch is also not short-circuit signs readily connect to other parts again still boot failure.

As the power of “suspects” the greatest, I have decided to replace the method used to verify, just-on-hand to have a 250W power supply, installed after the computer is still “silent”; Is this 250W power supply is Li dell latitude d520 battery, dell latitude d600 battery, dell latitude d610 battery? At this time I noted the chassis installed in the four IDE devices: two hard drives and two CD-ROM. Friends said that just to upgrade, it appears that is likely to be caused by excessive power supply, two of which I immediately unplug the power plug of equipment, try to boot, the computer has not the slightest reaction.

While I am prepared to give up when suddenly the computer’s power supply fan spinning up, then heard the sound of the hard drive self-test, the display is also slowly changing light, the computer launched! But soon, start interrupting, showing “CMOS Load Failure”, and prompted by the “F2″ key to start, according to “Del” to enter the BIOS settings, no matter, I press the F2 key to enable the system to continue to guide, but in any case can not enter the Windows XP desktop, had to restart. The press “Del” key to enter the BIOS settings, friends trying to enter a password, but directly to the, and found the time to view positioned at 0:00 on January 1, 1999, and it is clear the CMOS gd761, td347, dell inspiron 6400 battery is dead . Immediately bought a new battery into one, and all equipment connected to the boot again, the smooth startup of the computer, but still showed “CMOS Load Failure”, had no choice but to enter the BIOS settings to choose “Load BIOS SAFE DEFAULTS” and restart the smooth into the Windows XP desktop, and all the restoration unabated. In the thought that the problem has been resolved, the friends suddenly find missing floppy drive icon, the system did not identify the floppy! Is just now beginning to think that the song might touch the floppy drive connection, so no choice but to open the case more thin, but still can not see the boot floppy. Calm down, just recall the operation “Load BIOS SAFE DEFAULTS”, the floppy drive is set to the default “None”, and restart to enter the BIOS settings, was to prove my idea to come back immediately, with a floppy drive while .

Recalling the whole process, everything is small CMOS battery to blame, it seems that analysis can not be in accordance with the experience of walking, but should be adaptable, to deal with the specific environment; as to why no power CMOS, the computer can start suddenly, Although my analysis may be connected to power after the computer does not start, but the power supply has power to the motherboard, the motherboard CMOS battery to be sufficient dell inspiron e1505 battery, dell inspiron 6400 battery power to start the computer, they have taken place in front of the scene.
