Lenovo BIOS firmware update

Lenovo BIOS firmware update

Lenovo has urged its users to download and update the latest BIOS firmware update that disables a controversial “unwanted software” from Lenevo PCs, notebooks and laptops.

After much criticism, Lenovo finally broke silence on the matter- unauthorized installation of certain programs in large number of Lenovo computers. The company was using a “rootkit-like” technique to install certain programs forcefully on a large number of its Windows laptops and PCs. Lenovo was using BIOS to keep track of certain applications on Windows’ system files and overwrite it on boot-up with its in-house alternative called Lenovo Service Engine (LSE).

Furthermore, a vulnerability was found in the way the company was tweaking the BIOS. The vulnerability, if exploited, allowed an attacker to gain admin-level access of the system and install malicious code. Lenovo issued a patch to fix it on July 31, but it requires manual installation.

In a public announcement, the company has now said that its latest BIOS firmware, which was released on July 31, disables the script which allowed automatic reinstallation of unwanted software even after a full Windows wipe. The vulnerability affected a large pool of Lenovo PCs and laptops including Flex 3 1120, Yoga 3 11, and Horizon 2 27 among others. All the new laptops that shipped after June 2015 aren’t affected with the said vulnerability.

“The vulnerability was linked to the way Lenovo utilised a Microsoft Windows mechanism in a feature found in its BIOS firmware called Lenovo Service Engine (LSE) that was installed in some Lenovo consumer PCs. Think-brand PCs are unaffected,” wrote Lenovo.

“Lenovo and Microsoft have discovered possible ways this program could be exploited in the Lenovo Notebook implementation by an attacker, including a buffer overflow attack and an attempted connection to a Lenovo test server.”

The update firmware is available to download from company’s website. Depending on the configuration of your BIOS, Lenovo has also put up instructions to help you install the update on your machine.

The full list of impacted products is as follows:

Lenovo notebooks: Flex 2 Pro 15 (Broadwell), Flex 2 Pro 15 (Haswell), Flex 3 1120, Flex 3 1470/ 1570, G40-80/ G50-80/ G50-80 Touch, S41-70/ U41-70, S435/ M40-35, V3000, Y40-80, Yoga 3 11, Yoga 3 14, Z41-70/ Z51-70, Z70-80/ G70-80.

Old Laptop Batteries Could Power Slums in India

Old Laptop Batteries Could Power Slums in India: IBM Study

Many of the estimated 50 million lithium-ion laptop batteries discarded each year could provide electricity storage sufficient to power homes in developing countries, researchers at IBM say.

The researchers at IBM Research India in Bangalore found that at least 70% of all discarded batteries have enough life left to power an LED light at least four hours a day for a year.

While it’s possible to combine LED lights with solar panels and rechargeable batteries, using discarded batteries could make the approach far cheaper.

“The most costly component in these systems is often the battery,” says Vikas Chandan, a research scientist at the lab’s Smarter Energy Group, who led the project. “In this case, the most expensive part of your storage solution is coming from trash.”

The IBM group, working with a hardware R&D firm called RadioStudio, tore open discarded laptop battery packaging and extracted individual storage units called cells, tested those individually to pick out the good ones, and recombined them to form refurbished battery packs. Then, after adding charging dongles as well as circuitry to prevent overheating, they gave them to five users in Bangalore who lived in slums or operated sidewalk carts. Three months later, the users said the battery packs had worked well.

Around 50 million laptop and desktop computers are discarded in the US every year, according to the Environmental Protection Agency. Meanwhile, in India alone, about 400 million people lack grid-connected electricity.

laptop battery life

How to Increase battery life of your laptop?

There are simple techniques available to extend battery life of your laptop. Some of these tips are for when you need to increase your battery at that very moment, while others are preventative measures, best implemented before your battery life comes up short.

Step 1: Click on the Start Menu and type “ CMD ” in the Start Search bar.

Step 2: The search will start and it will then display an icon of “ CMD ” . simply right click on it and select Run as administrator.

Step 3: It will open command line, now simply run the command “powercfg -energy” without quotes. (For windows 7 users.)


Simply run the command “powercfg /energy” without quotes. (For windows 8 users.)

Step 4: Now Press “Enter”.

Once you successfully execute this command , Windows will run a complete scan of your system and it will find some ways to improve performance and power efficiency.
The results of this process will be saved to an HTML file, which is commonly present in the “System32” folder of most of the systems.

To access this file, simply follow the path which will be displayed in command prompt window after completion of the command. Read This file to understand that what program in your system is consuming more power and degrading the performance.

To save power, make your computer do less in general:

  • Don’t use a screensaver. They’re unnecessary on modern displays and will drain your battery to do nothing useful when your display could be off and saving power.
  • Reduce Screen Brightness
  • Have Your Display Automatically Turn Off
  • Run fewer programs in the background.
  • Disable Bluetooth and Other Hardware Devices
  • Reduce CPU usage.
  • Avoid maxing out your RAM. If your laptop’s RAM is full, try to make more RAM available — close programs running in the background or try to upgrade your laptop’s RAM.

How to play DVDs and Blu-ray discs in Windows8 ?

Windows_8_Media_CenterA problem that many Windows 8 users is facing is that it will not play your DVDs or Blu-Ray discs. The reason is that Microsoft is not paying for the right to use the patented software technology needed to play DVDs anymore because most devices in the market nowadays do not even have optical drives. If you are a movie buff you will have to find third-party software that can play your disks such as VLC.

If you want to enhance Windows 8 you will have to pay Microsoft extra money to download the Media Centre software. This will enable DVD and Blue-Ray support. If you are using plain vanilla Windows 8 you will need to upgrade to the Pro pack, which comes with Media Center and some other unrelated features. Microsoft itself advises people to buy third-party DVD software instead of doing this. This is because upgrading will cost you more than Rs 5,000. It is best to avoid it.

If you are already using Windows 8 Pro you can download the Media Center pack for around Rs 550. Just open Control Panel, and click “Add Features to Windows 8”. You will be shown the upgrade available, depending on which version of Windows 8 you are using.

Those who have bought the Enterprise edition of Windows 8 will not be able to download the Media Center pack. It is best for them to download or buy additional software.

How to replace the hard drive for your laptop?

laptop hard driveBefore removing the hard drive manually, you must keep in mind that it is a not easy job which should be done with utmost care and caution. You must carry a set of small screwdriver because it will help you to open laptop’s hard drive. In case you are not sure enough about the way of taking of the hard drive from the case, it is better to refer the user manual. Get some tips from the user manual of how hard drive has to be taken out of the laptop. Once you take it out from the case, things become really easy for you because you can now know the dimension as well as type.

Problems are not yet over as there are a lot of laptops that use hard drives of the same dimension so again you need to find out the most appropriate hardware to go well with your laptop.

Once you finally get the correct hard drive for your laptop, you also need to check the type of connection which is compatible with the laptop. Mainly there are two types of connection – SATA and PATA are used to connect drives to the laptop. In case you have purchased the laptop within the last six years then most probably it would have SATA as it is an industry standard which is used with most of the PCs. But if it manufactured before 2003 then probably it would have a PATA connection which is outdated now.

Just have a quick look on the back of the drive which is labelled with the connector type. Now use the connector accordingly and place the hard drive in its place within the laptop.

Know About Your Laptop’s Battery Status With BatteryBar

batterybarBatteryBar, a superb power gauge that’s compatible with XP, Vista, and Windows 7.

Normally, if you want Windows’ read on how much battery life is left, you have to mouse over the tiny System Tray power icon. BatteryBar adds a full-time, at-a-glance gauge to the right side of the taskbar.

That gauge shows you either a percentage of battery life remaining or the amount of runtime left; clicking it toggles between the two readings. Interestingly, when you’re running on AC power, the gauge switches from green to blue and shows how long until you reach a full charge.

But wait, there’s more: when you mouse over the gauge, a pop-up window displays a boatload of additional information, such as total battery capacity, charge/discharge rate, AC status, and even a lifetime estimate based on historical charge/discharge data. That’s what I’m talking about!

BatteryBar is free, there’s also a Pro version that adds more features, like a graph of battery profiles, low/critical power warnings, and automatic power-scheme switching that kicks in when you switch between AC and battery power.
