8 hours battery, rubbish

My Acer laptop has to have eight hours of talk time. However, each time I reload completely, then ONLY SURF THE INTERNET USING A ADAPTER WIFI which is connected via USB (NOT WATCH ANY VIDEO, NO AUDIO... Everything SIMPLY SURF the WEB), how is it, my battery is not going for more than four or five hours when in fact the laptop I bought is advertised as a ' 8 + hrs to GO ANY DAY! ' laptop?  What is the WIFI connection itself which is swallowing the battery? Thanks in advance for your answers.

Joe

Hey Joe,

8 hours is the wait time for a battery. When you use the laptop it won't have 8 standard hours. More when you use the devices as Wifi and other devices usb battery is consumed more. Drain the battery only USB devices.

    Hi Krishj,

    In my battery of 4-5 hours notice, life is beautiful and everything is ok with your computer laptop because it s always according to your use. If you run a large number of programs and using the brightness of the display, the laptop needs more energy. Which is a perfectly normal behavior.

    Usually 8 hours autonomy you will have with the brightness of the display only low and high level of energy saving.

  • Satellite A200 - 1 H 2-1 hour battery drains

    Hello

    I bought a new Toshiba Satellite A200 - 1 H 2 2-3 weeks. Sound obtained by T5440 Core3Duo, 2 GB of RAM, ATI Mobility Radeon HD2600GT 256 dedicated (up to 1025 with turbomemory).
    I am aware that I got a fairly good CPU and GPU and they cost power.

    But is this normal when POWER safe mode on my battery drains completely in a little more than 1 hour?

    Elwin

    Hello

    Battery working time depends on the use of the laptop!
    But as far as I know the A200 runs approximately 1.15 hours on battery

    In addition, the laptop came with a standard battery.
    If you need more power, you should buy a stronger battery with 6000mAh or higher.

  • Satellite L650 - 18 c - 0% charged after 2 hours battery

    Hi all

    I have a brand new (got three hours ago) L650 - 18 c, which does not seem to load correctly. When I hoover my mouse over the battery icon that it said that AC is connected and load but the battery status is always 0% and it is bound for at least 2 hours now. He shows no sign of support either.

    Does anyone have any advice or ideas for what is the cause and how to fix it?

    Thank you

    Hi been,.

    In your case I'd wait a bit more. I mean this new book of s you have only several hours and this could take some time until the battery is fully charged.

    In your case I would also turn the computer off and wait until the LED battery icon change color and show you a completely charged battery.

  • Z10 blackBerry dead after only 5 hours battery

    I don't want happened to my Z10, but after only 5 hours and no use a fully charged battery is dead. I bought a new battery but no change. I wish there was an option to completely reinstall the operating system. I have installed all apps

    Always start with a battery pull when something goes wrong with your phone.  There could be something in the operating system that is not aware and a battery pull will often correct this.  To make a correct battery pull, remove the battery while your phone is on, then replace it.

    I hope that helps you.

  • Exists for Qosmio F a battery with 8 hours life?

    Hello
    I noticed that TECTRA R600 has a good life up to 8 hours battery.

    Is there also for qosmio?
    And what is not. If they are available.

    I'm pretty sure that there is no battery with the life of 8 hours available.

    Computers laptop Tecra don t have high-end hardware and they are optimized to save energy you can work long on battery.
    Sorry, buddy, but a Qosmio laptop needs a lot more power as a Tecra but the Qosmio is faster.

    Moreover, on the Toshiba site, you can search for compatible batteries:

  • Satellite L30-105: Question on working time of battery

    I think of buying one of them, but the 1.5 hours battery life put me off a bit.
    Can someone give a review? It's all good, and not really the battery only last an hour and a half?

    Thank you. : o).

    Well, the laptop uses a standard 2000mAh battery PA3450U.
    The 2000mAh isn't exceptional value.
    The laptop should run with battery about 1 h 30 min.
    Of course real time depends on the use of the laptop.

    But you can upgrade the farm a much stronger battery;
    To my knowledge the mobile phone should support:

    Battery Pack (6 cells, 4300mAh) PA3399U-1BRS
    Battery (Li-ion, 4000mAh, 6 cells) PA3465U-1BRS
    Battery (Li-ion, 4300mAh, 8 cells) PA3457U-1BR
    Extended capacity battery (Li-ion, 6000mAh, 9 cells) PA3478U-1BRS
    Battery high capacity Pack (Li-ion, 12 cells, 8600mAh) PA3400U-1BRS

    The 8600mAh battery is about 4 times stronger than the 2000mAh

    However, the battery seems to load. When I work with netpower and I disconnect netpower, yet portable functions on battery.
    Any suggestions what could be the cause and what todo?

    [Edited by: admin]

    Hello

    The machine is new and it should work properly. In my opinion, you should contact your local dealer and tell him that you want to have a new unit. As far as I know that you have 14 days return altogether.
