Laptop battery calibration techniques05.26.14

Shorter battery life, not the battery itself.

For the battery using time within 1 year, shorter battery life, often not because of battery normal aging, but because the battery in the process of many times of charging and discharging, notebook BIOS system has a miscalculation on battery power. Original battery has a certain power, but mistakenly think that the BIOS battery has run out, let your laptop to force to turn it off. If appear this kind of battery life shrink, the first battery quality problem is not busy to conclusions, and can be done by “cell calibration” this simple and easy way to let the rest of the power out into full play.

How to make “battery calibration”

Battery calibration method is more than one, there are generally three kinds of ways: using BIOS battery calibration program, manual Battery Calibration and use third party Battery Calibration software. Here mainly to talk about the first two correction methods.

Tips: do not recommend the use of third party Battery Calibration software. As for the reason, first of all need to install third party software, not the former two methods is simple; secondly, the correction principle behind is similar, there wasn’t too much unique local third party software, but also a potential security risk. So in the front two methods can complete battery calibration case, does not recommend the use of third party software.

The standard correction: correction function used the books of BIOS battery

Many brands of laptops in the BIOS, integrated with battery Calibration procedures, general English is called “‘ Calibration”, namely “Battery check”. Directly into the laptop BIOS battery calibration operation, will be finished here in asus notebook, for example, simple talk about how to operate, the operation of the other laptop similar way.

Step 1: boot, boot screen after press “F2″ to enter the BIOS menu; Through the or so direction key, the Power menu choice.

Step 2: enter the Power menu, you can see “Start ‘Calibration” option, select it and press the return key.

Step 3: then the screen will become blue, have English tips, and requested the notebook power adapter plug in to recharge the battery. After the battery is full, such as screen and prompt the user to disconnect the ac adapter. Notebook to continue after discharge the battery until the battery runs out.

Step 4: the process over a period of time, such as automatic shutdown after its battery runs out, then plug in the ac adapter to recharge the battery, but don’t start up. (charge indicator extinguished) after fully charged, such as cell calibration process is completed.

This operation is the official battery correction method, the entire process takes about 4 to 5 hours and more time-consuming. If you find that your laptop battery doesn’t work long time, such as a few months, battery life is better than at the beginning, and laptop BIOS with this function, suggested to implement it.

Introduce the necessary procedures manual Battery Calibration

Step 1: in the operating system (Windows XP), into the “power options”. “Choose to use the scheme of” power to “open”, and to “close the monitor”, “off the hard disk” is the most short time, while the system standby should be set to “never”.

Step 2: in the “Power Options” “alert”, cancel all alert options, the purpose is to let the battery is fully drained until the shutdown.

Step 3: set of finished, close the application, all closed WIFI, unplug the power adapter, battery powered. Don’t do any operation, until the battery is depleted shutdown. The estimation process is relatively long, may take several hours. After discharge, even the power adapter, the battery is full, then completed a battery calibration.

After correction, whether to try the battery life time increased, if not clear, can be in accordance with the above method again, but is not recommended for regular. If the battery has a long time of use, and the battery after correction, the effect is not obvious, it may be the battery life of its own natural aging. In addition, if the laptop battery is normal, we do not recommend battery calibration operation.

Ultrabook – Long Battery Life?07.07.12

battery-life

“Bandwagons, trains and Tranes. Can’t say that these three have a heck of a lot in common in most regards, but one thing’s for sure: trying to stop this trio would be a Herculean task. And so it goes with laptops — once upon a time, it was good enough to have something that resembled a portable tower, but these days, the ability to even see the chassis at all feels like a negative. I exaggerate, of course, but the proverbial race in the laptop world is hardly about price; it’s about thinness.”

An interesting ‘form vs. function’ discussion. The holy grail here, as one would expect, is a laptop an inch or less thick, with battery life of a full “business day,” while operating at full tilt. While battery technology has certainly improved, it’s not enough to coax much more than ~4-6 hours of intermittent use out of today’s (Ultrabook) batteries. It seems that the goal of 24-Hours is obtainable, but not with this less-is-more footprint. Is going back to the 4-5 pound 1-inch+ thick laptop the answer? Better battery technology is coming, but probably not soon enough for most users. Other thoughts: Making a ‘battery slice’ affordable and available for all models? Replacing the physical keyboard with a tablet-style virtual keyboard, freeing-up space for a larger battery (then why not just use a tablet?)? Unbreakable solar panels in the cover to constantly charge? Wireless Charging not requiring <1m proximity? Inventors? Any ideas that you can share?

HP ProBook 5330m04.19.12

The HP ProBook line of business notebooks has always attempted the meet the needs of businesses and consumers alike. The new HP ProBook 5330m looks like the perfect solution if you want a powerful, aluminum-wrapped laptop for work and play but can’t afford a MacBook Pro. Is it possible to find a lust-worthy business laptop for $899 or less? Keep reading to find out.

Build and Design
Let’s be honest. Anyone who thinks the new HP ProBook 5330m wasn’t designed to directly compete with the 13-inch Apple MacBook Pro is likely suffering from some type of delusion. The 13.3-inch ProBook 5330m combines all the aluminum-clad beauty of the MacBook Pro with the Windows-based business features of the HP Elitebook laptops.

The 5330m is less than 1-inch thin (if you don’t count the rubber feet on the bottom of the notebook), features a dual-tone color scheme, brushed aluminum chassis and backlit keyboard and is HP’s first business notebook to offer “Beats Audio” with software-enhanced audio playback over the built-in speakers and the earphone jack. The ProBook 5330m features a 13.3-inch anti-glare display (1366×768) and second-generation Intel Core i-series processors, including the dual-core i3 and i5 variants. It does not have an internal optical drive but weighs only 4.0 lbs.

The design is a quantum leap over most of the previous HP ProBook laptops — which are mostly just low-cost alternatives to the enterprise-class HP EliteBook line. The 5330m gives you the durability of aluminum construction combined with an underside made of magnesium alloy and covered in rubberized black paint similar to what you’ll find on the Lenovo ThinkPad line of business-rugged notebooks.

Overall, the build is exceptionally strong for a notebook that has a starting price of just $799. At first glance the build and design has a lot of drool-worthy elements for both IT geeks and average computer users. Of course, you can’t have everything on a budget.

Ports and Features
Most notebooks designed for business have an impressive array of ports so you can connect your laptop to any number of devices. Unfortunately, HP didn’t include that many ports since the ProBook 5330m was designed for budget-conscious businesses and consumers. Of course, you also don’t get a built-in DVD drive. What you do get are two USB 2.0 ports (three if you count the eSATA/USB 2.0 port), Ethernet, VGA, HDMI, an SD card reader and a headset jack.

Gone are the days of ExpressCard expansion slots, FireWire or dedicated microphone and headphone jacks. HP decided to offer HDMI on the 5330m rather than DisplayPort since more consumers will likely connect their notebook to consumer-grade monitors or HDTVs. The only connection I’m disappointed isn’t here is a USB 3.0 port. USB 3.0 is the new USB standard and we’re seeing more and more external storage and accessories take advantage of the faster speeds offered by this port. I understand that HP was aiming for a street price of $899 or less, but this 5330m should have come with USB 3.0.

Battery life
The 5330m’s small four-cell battery lasted three hours and twenty-six minutes in our battery rundown test, which involves playing a movie off the hard drive over and over with WiFi on and the screen’s brightness set to 65 percent. Typically, we like to remind readers that that’s a taxing test, and that you might expect longer battery life if you plan on staying inside your browser. In this case, though, we were on track for a similar time of four hours when we went about our usual routine, which includes checking and responding to Gmail messages, reading various blogs, streaming music through Grooveshark, and writing reviews, like this one. After an hour of doing all those things in the cloud, our battery life rating fell 30 percent.
The real shame here isn’t so much the battery life, since the X1 notched a near-identical score with a similar processor-graphics card combo. (To be fair, of course, the low-powered MacBook Air made it nearly five hours, while the Samsung Series 9 came close to four and a half.) Rather, we have a bigger problem with the fact that this business laptop, of all things, isn’t offered with an extended or slice battery, which is how Lenovo is compensating for the X1’s less-than-stellar longevity. You can buy a spare for $129, but it’ll have the same limited capacity as the battery that comes with the laptop.

HP G62 Information and Review03.21.12

Quick Specs

Screen Size: 15.6-inches
Processor: Intel Core i3-370M, Celeron 900, Celeron T3300, Celeron T3500
Graphics: Intel HD or Intel GMA

Good

  • Good range of ports
  • Decent screen
  • Large hard drive

Bad

  • Drab design
  • Poor 3D performance

Replacement Accessories

The G62 doesn’t exactly set the heart racing when you first clap eyes on it.  Nevertheless, unlike Toshiba’s Satellite Pro C660, the chassis does feel very solid. We reckon it’ll stand up to some long-term abuse. Also, although the matte finish is drab, it’s less likely than some other finishes to show up scratches. Rather than opting for a keyboard with isolated keys, as seen on Apple’s MacBooks, HP has instead gone with a more traditional set-up. Still, the keys are flat and have a raised centre, so they feel similar to those on an isolated keyboard when you’re tapping away on them. We’d prefer the keys if they had slightly more travel to them, though.

The HP G62 is difficult to get excited about. It’s not a bad laptop but, compared to some of its slightly cheaper rivals, it comes off second best.

Review Dell Vostro V13 Notebook03.15.12

The V13 is one of Dell’s Vostro range of small-business notebooks, though you wouldn’t know it to look at it. Its extremely slim exterior, with design elements borrowed from the Dell Adamo Thirteen, brings a touch of style to the dull business arena. The newcomer hopes to offer increased productivity and security, and is equipped with the latest technology. Find out how successful it is in our comprehensive review.

Case

Tightly packed insides

Thin aluminium sheet instead of the usual plastic

The case is made almost completely of aluminium, which strikes us as highly unusual given the price of the laptop. It is the kind of high-quality material you would expect to see on expensive portable computers like the Apple MacBook Pro or the Dell Adamo. The V13 is only a few millimetres larger than record-holders such as the Apple MacBook Air, the Samsung X360 or Dell’s own Adamo Thirteen.

Connectivity

The layout of the ports, in our opinion, has been perfectly successful, with audio ports for a headset positioned on the front, card readers on the side, and all other connections on the back. This is perhaps slightly less convenient for adding and removing peripherals, but it leaves your work area less cluttered.
