HP Presario CQ42 is an inexpensive entry-level laptop, what was rather notable about the CQ42 was the battery performance. Cheaper laptops traditionally ship with weaker notebook batteries to shave even more cost off the bottom line, but HP CQ42’s six-cell Lithium-ion HP 593554-001 battery managed a perfectly respectable two hours and 22 minutes in our punishing full-screen, full-brightness video test with all battery-saving measures disabled.
Improve HP 593554-001 laptop battery life and performance
1. Single-task, not multi-task. The more you are doing at the same time with your notebook, the more memory and CPU usage increases. Both of which directly use up hp 593554-001 laptop battery. Close any applications you aren’t using, even the small ones. While your hard drive uses the battery too, if you are doing anything ‘productive’ you are probably hitting the drive on a regular basis anyway.
2. Condition the HP pavilion battery. When you purchase your HP Laptop Batteries, charge the HP laptop battery to 100 percent, discharge it completely, and then fully charge it to 100 percent again to help the hp 593554-001 battery computer HP laptop remember exactly how much electrical charge it can hold. From then on, you’ll never need to completely discharge the battery again, but always make sure when charging it that you let it reach 100 percent. AussieBatt told us to “remember to plug in the HP COMPAQ Business Notebook nc6000 AC Adapter whenever you get a chance. Most laptops will recharge quickly.
3. Keep laptop battery cool. You can take a page out of the extreme gamer’s handbooks, and have your system perform more optimally by keeping the hp cq42 battery cool. Make sure your air vents aren’t blocked by anything, which often occurs by poorly positioning your notebook. Heavy CPU and memory use all contribute to heat as well, hence my comment on multi-tasking above.
4. Power down the display. “You can often yield up to ten minutes of hp presario CQ62 battery life per level of brightness lowered,” said Salinas. In addition, lowering the screen resolution and color depth decreases the workload on the GPU, thus extending the battery runtime. You can change these by going to Start/Settings/Control Panel/Display and clicking the Settings tab. Disabling extra features like ClearType fonts and fade effects will cut down on the CPU’s power consumption. You can find these in the Control Panel under System/Advanced/Performance Settings/Visual Effects.
5. Decrease laptop computer hard drive activity. To minimize the frequency with which your hard disk has to spin up to access data, Salinas recommended defragmenting your hard drive regularly. This optimizes the placement of data on the drive so that it can be found more quickly. You can find the Disk Degfragmenter in the Start/Programs/Accessories/System Tools menu. Beyond that, he advised optimizing Windows’ paging file, which is an area of the hard drive that serves as virtual memory whenever your RAM is full.
6. Turn off unused devices. Both of our gurus mentioned disabling unused devices. Many new notebooks provide a hard-wired On/Off switch for the Wi-Fi radio for this reason. Beyond that, you should go to the Control Panel, select System/Hardware/Device Manager, and disable the Ethernet hp pavilion dv6000 adapter, infrared transceiver, and Bluetooth radio. It was designed for mobile devices, but having Bluetooth enabled actually consumes quite a bit of battery power.
