1. Enable pipelining

Browsers are normally very polite, sending a request to a server then waiting for a response before continuing. Pipelining is a more aggressive technique that lets them send multiple requests before any responses are received, often reducing page download times.

To enable it, type about:config in the address bar, double-click network.http.pipelining and network.http.proxy.pipelining so their values are set to true, then double-click network.http.pipelining.maxrequests and set this to 8.

Keep in mind that some servers don’t support pipelining, though, and if you regularly visit a lot of these then the tweak can actually reduce performance. Set network.http.pipelining and network.http.proxy.pipelining to false again if you have any problems. More »

Have you ever run out of battery power on your mobile PC during a meeting or a class? Have you worried about running out of power while waiting to meet with a client? Have you asked yourself how much longer your battery will last? Sufficient battery life is a persistent challenge for mobile PC users. But Windows offers several ways to help maximize the battery life of your mobile computer.

In this article, I’ll discuss how to take advantage of Windows settings to manage power more efficiently. I’ll also introduce some non-software related tips that you can use to extend battery life.

Optimize your power settings

Windows 7

Windows 7 has two default power plans:

  • Balanced: Automatically balances performance with energy consumption on capable hardware.
  • Power saver: Saves energy by reducing your computer’s performance where possible.

Change your power plan

1. Click the battery meter icon, located in the notification area on the Windows taskbar.

The display and hard disk on your mobile PC are the two biggest consumers of battery power. By choosing a power plan (called a power scheme in Windows XP) you can extend your battery life. A power plan is a collection of hardware and system settings that control how your mobile PC manages power.

2. Select either the Balanced or Power saver power plan.

Windows Vista

Windows Vista has three default power plans:

  • Balanced. Offers full performance when you need it, but conserves power when the computer is idle.
  • Power saver. The best choice for extending battery life. The cost? Slower performance.
  • High performance. Maximizes system performance at the expense of battery life.

Change your power plan

1. Click the battery meter icon, located in the notification area on the Windows taskbar.
2. Select the Balanced, Power saver, or High performance power plan.

Windows XP users

Windows XP includes two power schemes that were created specifically for mobile PCs.

  • The Portable/Laptop power scheme minimizes the use of power to conserve your battery, but adjusts to your processing needs so that the system speed is not sacrificed.
  • The Max Battery power scheme minimizes power use but does not adjust as your processing demands change. You should use Max Battery only in situations that require minimal processing, such as reading documents and taking notes in a meeting.

Use a power scheme designed to maximize battery life:

1. Click Start, and then click Control Panel.

2. In Control Panel, verify that you’re in Category view, and then click Performance and Maintenance.

3. In the Performance and Maintenance window, click Power Options.

4. On the Power Schemes tab of the Power Options Properties dialog box, click the arrow under Power schemes, and then click Max Battery.

5. Click OK.

You can also create a custom power scheme to suit your specific needs. You can create as many custom power schemes as you want.

Take advantage of low-power states

The different versions of Windows provide the following battery-saving states:

  • Windows 7: sleep and hibernation (which is like deep sleep)
  • Windows Vista sleep and hybrid sleep (which is a combination of sleep and hibernation)
  • Windows XP standby (which is like snoozing) and hibernation (which is like deep sleep)

Sleep (Standby)

In a sleep state (standby), your display and hard disk turn off, and all open programs and files are saved in random access memory (RAM) your computer’s temporary memory rather than to the hard disk. Information stored in RAM is cleared when the computer turns off, so it’s a good idea to save your work before placing your system in standby mode. Otherwise, you may lose data if you lose power, you swap batteries, or your system crashes.

Sleep (standby) is particularly useful when you’re using your mobile PC intermittently during the day. For example, when driving between clients’ offices during the day, put your computer to sleep or on standby to maximize the life of your battery and maintain quick access to open programs, files, and documents. When you want to use your computer again, it wakes up quickly, and your desktop is restored exactly as you left it.

In certain scenarios users of Windows 7 and Windows Vista can experience problems when connecting their mobile computers to some Wi-Fi hot spots. According to Microsoft, symptoms will vary, and can include poor performance as well as having the wireless network connection dropped altogether. The Redmond company revealed that these issues are also associated with mobile machines which are running on battery power. The software giant noted that customers running Windows 7or Vista mobile PCs and connecting them to wireless access points (AP) also reported these issues.

“This issue occurs if the Wi-Fi hot spot uses wireless APs or routers that do not support the 802.11 power save protocol,” Microsoft informed. Still, the power saving features built into both Vista and Windows 7 by default, contribute to this problem. Essentially, when a Windows 7 mobile PC is plugged into a power source, the wireless network adapter will go into Maximum Performance mode and switch off 802.11 power save mode. More »

An integral part of the Software Assessment Management efforts from Microsoft, the Microsoft Software Inventory Analyzer 5.1 is available for download accompanied by a range of resources designed to streamline usage. MSIA is a tool designed to permit customers to scan either a local machine or computers connected to a network in order to identify and produce a report containing a list of core Microsoft software products installed. In addition to MSIA, the company is also offering for download documentation containing a User Guide and a FAQ. According to the Redmond giant, MSIA is capable of putting together software inventories only for networks with a maximum of 250 computers.

“MSIA reports the results of the scan in three possible formats, based on the user’s selection: HTML, Excel, and Text. These reports contain details such as the names of all the installed Microsoft products, links to the list of computers scanned, links to the error log, and so on. In addition, the summary report enables users to enter corresponding license purchase information for all software detected in the scan,” Microsoft revealed. More »
