The standard Toshiba Portege M400 battery is with 4400mAh that can make your Toshiba M400 laptop run around 2-3 hours in normal use like HP Pavilion DV2000 battery and Sony VAIO PCG-V505 battery. But when you are in a long flight or in a long day course away from a wall socket, it’s easy to run out of power. Here are some tips for your laptop running longer:
a) Remove External Devices, and Change Your Laptop Power Setting
Just like most of the laptop batteries, dimming the brightness of your Toshiba M400 laptop screen can conserve the M400 laptop battery power. Besides, remove all CDs or DVDs from your optical drives, and do not connect any USB drives, turn off Bluetooth, Wi-Fi, and 3G networking. Also, tweak your Portege M400 power setting to conserve the Portege M400 battery. For example, in Windows operation systems, go to power options in the control panel and adjust the “power saver” setting.
b) Have a Second Battery, and Get to Know the Battery Spec
Nowadays, there are many aftermarket laptop batteries which are at lower price but with no bad quality thanks to the advanced technology. If you have to stay outside all day long and it’s not easy to find a wall socket, a spare battery is necessary.
When buying an extra battery for Toshiba Portege M400 laptop, you need to know how much capacity the battery has. The more capacity a battery has, the longer it can last on a charge. No matter the suppliers provide specifications of cells, Ampere-hour, or Watt-Hour rating, the higher the number means the longer the battery can last.
c) Check for the Power Ports Before You Fly
Seatguru.com provides helpful seating configuration maps for most domestic and international airlines. The black dots on seat maps indicate the presence of in-seat power ports. So, before you fly, you can check the power port first to make sure where you can plug-in your laptop.
d) Play Music on a Portable Device
Play music or movies on your Toshiba Portege M400 laptop will drain your Toshiba M400 laptop battery. If you would like to listen to your own music during a long flight, you can prepare a portable media play to keep your M400 laptop battery power lasting longer.
e) Share an Airport Power Plug
There are some wall sockets at airport departure gate, but most of time they are taken. You can prepare a multiple-plug power adapter which lets you simultaneously plug up to three devices into one wall outlet
