Does it seem like no matter what you do, your computer is always out of battery power? It might be time to replace the battery. Every battery has a designed capacity-basically the amount of charge that it's designed to hold. Over time batteries lose their ability to hold a charge. This means that even though you're fully charging your battery, the actual amount of power that the battery can hold is going down.

Some of the telltale signs that your battery is going bad are shorter use times, and subsequently, shorter times to recharge. If you notice the amount of time you can spend unplugged is going down, then chances are your battery has lost much of its ability to hold a charge. Another sign that your battery might be on the wane is that it takes less time to recharge. A battery that's going bad might also cause your computer to turn off or hibernate unexpectedly, even if the battery meter displays ample capacity remaining (70 or 80 percent).

Fortunately, Windows can help you know when your battery is unable to hold a full charge. When your battery gets down to 40 percent of its original capacity (that is, it can only hold 40 percent or less of its designed capacity after it has been charged), you'll see a notification via the battery meter icon that your battery might be going bad. This notification is new in Windows 7-earlier versions of Windows can't notify you when your battery is going bad. If you don't want to receive this notification, you can turn it off by clearing the check box on the battery meter.

Many batteries will show signs of problems well before reaching 40 percent of their original capacity. Also, many computer manufacturers have programs that you can use to measure the performance of your battery. These programs might be more sensitive to battery problems and should be used first to check the condition of your computer's battery. For more information about solutions to this problem, see Solutions to common battery problems.

Note

Some computer manufacturers report the designed capacity of their batteries to be the level of the last full charge, so it's possible that your battery might be below the warning threshold without giving you any warning. If your computer continues to run out of battery too quickly, but your battery meter shows that it's fully charging, it might be time to consider replacing your battery. Check with your computer manufacturer for information about replacing your battery.

Using the battery meter to monitor power consumption

• The battery meter is a handy tool located in the notification area of the Windows taskbar that makes it easy for you to keep an eye your computer's power consumption. The battery meter icon indicates whether your laptop is plugged in or whether it's running on battery power . When you point to the battery meter, you can see the percentage of battery charge remaining as well as an estimate of how much time you have until you'll need to plug your computer in.
• When you click the battery meter icon, you can get more information-like which power plan you're using and, if you have more than one battery, how much charge is left in your second battery. You can also change power plans and access additional settings for managing more power options. For more information, see Battery meter: frequently asked questions.

Using power plans to save your battery

One of the easiest ways to save your battery without affecting the performance of your computer is to use one of the built-in power plans that come with Windows. Power plans are basically collections of hardware and software settings that control how your computer uses power. There are two power plans that come with Windows that are useful for laptops:

Balanced. This is the plan that most laptops use by default. It offers full performance and display brightness when you need it and saves power during periods of inactivity.
Power saver. This plan can help you get the most from a single battery charge. It saves power by reducing system performance and screen brightness.

In addition to the power plans that come with Windows, your computer manufacturer might offer additional plans. You can also create your own power plan, or customize the settings for one of the existing plans. For more information, see Change, create, or delete a power plan (scheme).

Getting the most out of your battery

In addition to using power plans to get the most mileage out of a battery charge, it's also important to take care of your battery to make sure you get the most life out of it.

• Make sure you're following the manufacturer's instructions for charging and maintaining your battery. Only use a charger and power cord supplied by the manufacturer.
• Don't let your battery get too hot (or too cold). A hot battery is a sign of trouble and usually means that your battery isn't working properly. You should stop using it right away. Also, make sure that your battery isn't exposed to extreme temperatures. Batteries are designed to work best at room temperatures. Avoid using (or even storing) batteries in extreme temperature conditions.
• Use your battery to keep it fresh. Don't keep your computer plugged in all the time. It's a good idea to discharge and then recharge your laptop battery about once a month. Also, you should let your battery run down before you recharge it.

Lenovo ThinkPad T61 Review

Lenovo ThinkPad T61 Review

ThinkPad T61 14.1" widescreen notebook

Important to note is that this review covers the 14.1" widescreen version of the T61 series. As with any laptop model series, there are going to be widely varying configurations you can choose that will greatly affect system performance.

Specs

• Processor: Intel T7300 Core 2 Duo (2.0GHz, 800MHz FSB, 4MB Cache)


• Graphics: Intel GMA X3100


• Operating System: Windows Vista Business


• Display: WXGA+ 1440 x 900 (LG screen)


• Hard Drive: 100GB 7200RPM (Seagate Momentus 7200.1)


• Memory: 2GB (1GB x 1GB), up to 4GB max


• Ports: 3 USB 2.0, 1 FireWire, Monitor out, modem, Ethernet, headphone out, microphone in


• Slots: 1 PC Card Slot, 1 ExpressCard slot (optional media card reader and Smart Card reader)


• Optical Drive: Ultra-slim Super-Multi Drive


• Dimensions: 13.2" x 9.3" x 1.09 - 1.26" (335mm x 237mm x 27.6 - 31.9mm)


• Weight: 5.1lbs

The good: Internal roll cage protects LCD; 802.11n Wi-Fi for faster wireless throughput; very small A/C adaptor adds little to overall travel weight; Intel's Active Management Technology provides remote support.

The bad: New Centrino technology doesn't offer outsize performance gains.

The bottom line: Lenovo's 14-inch ThinkPad T61 shaves a few millimeters off the company's more mainstream R-series laptops, but still boasts the same, solid ThinkPad DNA along with IT-friendly features by way of Intel's new Centrino Pro platform.

Design and Build

The ThinkPad T61 is a premium product with a durable build, it is geared towards business users or simply those willing to pay a bit more to get something that won't fall apart after 1-year of use. For somebody that travels a lot or relies on their notebook to earn a livelihood, the build and reliability factor is probably more important than having the latest and greatest components inside.

The keyboard remains the same between the T61 and T60 - meaning it's once again excellent. The only difference is that now there's more room on the keyboard side areas since the notebook body is wider, the speakers have been relocated to this extra real estate. The keyboard is spill proof and has two drain holes to make sure if you do happen to spill your morning Starbucks coffee, the liquid is carried away from sensitive components and out through the bottom of the notebook.

The hard drive is protected within the magnesium roll cage and shock mounted. Even if your T61 is dropped the included Active Protection System (APS) software will work with the on board accelerometer to detect a fall situation and end hard drive activity to prevent data loss.

Screen

The new widescreen format screen for the 14.1" T-series is either good, bad or somewhere in between depending on your personal preference. Lenovo will try and convince you widescreen offers more screen real estate and so it's better, the reality is the guys making the LCD screens are forcing it down the throats of the PC manufacturers because it's cheaper to make widescreen LCDs.

The particular screen I got is a WXGA+ resolution (1440 x 900). It provides easy viewing and you can fit a good amount on the screen, so no complaints on that front. The screen is crisp and there are no issues with graininess. The matte finish ensures there's little to no glare in office lighting situations.

Processor and Performance

The ThinkPad T61 now uses the Intel Centrino Duo (Santa Rosa) platform. You get a faster processor front side bus (800MHz), more processor cache (4MB) and an improved integrated graphics solution in the form of the Intel X3100. If all that talk is nonsense to you, then suffice it to say the T61 offers newer and better processing components than the T60. Will this performance be perceivable in helping to run MS Word faster? No of course not, but certain processor intensive tasks such as encoding video will be faster. And even if you won't be utilizing every ounce of processing power, just knowing the processor is faster and you're on top of the game is enough to make people like myself want to buy it.

Battery Life

+

One thing that's always a concern with a new platform is battery life. Reading the first reviews that came out about the T61 sounded like gloom and doom with reports of 2 hour battery life. It seems most of the initial reviews were done using very power hungry dedicated graphics solutions and with a 4-cell battery.

I had the opportunity to test a larger 6-cell battery on an integrated graphics system, and got 3 hours and 41 minutes of battery life under what I would deem normal usage. I was using the T61 with screen brightness set to half or lower, Vista battery optimized setting, wireless off to get this number. In a torture test, I set the screen brightness to top level, put in a DVD (Stargate) and played it until the lenovo battery hit 5% and the PC went to sleep – which happened after exactly 2 hours 15 minutes. I wouldn't call that bad, it'll get you through most movies.

The downside of a 6-cell battery is that it sticks out of the back (see pics) and weighs more, but I'm always be willing to carry a bit more weight for an extra hour of battery life. A positive comment that should be made is the power adapter is nice and small, it's actually the same size as the X60 ultraportable series adapter.

Keyboard / Touchpad / Pointing Stick

The ThinkPad T-series hasn't changed too much over time, and that's a good thing, there's no use changing something that's just right. The ThinkPad keyboard is one of, if not the best, notebook keyboards out there. There's zero flex, every key feels individual, every key has great travel/feedback and the keyboard is full-size.

The T61 has a pointing stick, I love using this and find it much easier than the provided touchpad - it makes it so you can move the cursor around the screen without having to lift your hand from the keys, a much faster and easier to control style of input. But the great thing is that if the pointing stick isn't your cup of tea then you've got the touchpad as well.

Wireless

The ThinkPad T61 uses the Intel 4965 wireless chip that offers 802.11 a/b/g/n wireless reception. All of your bases are covered there, and the greater range 802.11n offers is on the table if you have an 802.11n router. The range of the ThinkPad is theoretically greater now that the lid material has changed to plastic too. The antenna is run up through the lid for better reception you see, and the new lid material allows radio waves to reach the antenna more easily. I was only able to test up to 100-feet away from my NetGear WGR614 802.11g wireless router, which I despise for its bad performance and tendency to drop connections, but the T61 worked just fine with it and I never suffered a connection drop and throughput was consistently good.

Regulatory changes affecting the future of the French photovoltaic solar cell market in the country

Regulatory changes affecting the future of the French photovoltaic solar cell market in the country

According to reports, the French government has passed the French Parliament approved the country's biggest photovoltaic regulations a modification, this is undoubtedly the French and European solar power industry a huge impact.

An earlier start in the European solar power, especially in Switzerland and Germany, solar power system construction and application of leading edge stand in the world. Energy shortage in the traditional environment, the French once again aware of the limitations of traditional energy sources and the need for the development of solar power.

From 2006 to 2007, the French solar industry almost three times the market growth in 2006, the French solar power generating capacity of 10.3 megawatts (MW), 2007 generating capacity jumped 30 MW (MW), enough to see the impact of solar power so great for France. While the generating capacity of 30 MW for Germany or other European cities is still small, but such a huge growth rate, no doubt the French solar industry had a shot of vitality agent!

Revised policy later in the solar PV in the next 20 years, the development of new energy patterns with solar power industry, including solar power technology, research, solar power station construction and the daily lives of some applications of solar cells. Estimated 2028 in the whole French territory, solar power generation can reach 7GW.
