    Hi tuandinh1501

     

    The battery reset hole is just that - it resets the battery if you have any problems with it - a bit like taking out the battery, and re-inserting it.

     

    It is usually impossible to get into a computer that has a lost BIOS password.

     

    SOMETIMES, this method works.  Reboot your laptop, and when prompted for a password, guess three times. A screen will appear telling you that your system is disabled, and it will give you a code. Write down the code and go to http://bios-pw.com/ . This site will give you a BIOS password that MIGHT work. Reboot and enter the new password.

     

    Thanks to fellow ACE, Vince53 for the info!

    Thank Vince53. I try master password an I can get access to Bios.

    I have another question. My lap is model v7 581p. The backlit keyboard is defualt turned on when I start computer, can I change backlit to defualt turned off at starting?

    There may be an option in BIOS that will allow you to turn off the backlit keyboard. Failing that, check to see if there is any settings (possibly in Contol Panel) that you can change....

    I have one question. My laptop is ultrabook so I can not remove the battery after fully charging. But when i keep plug in the adapter. My lap does not stop charging when the battery is full - it states "100% - plugg in, charging". You can look the photo I attach below. How can I stop charging when still plugging in. 

    If I keep doing like this. Is it harmful to the battery life?

    Hello again!

     

    It might be that BIOS is not recognising that the battery is fully charged, although I must admit, I've not personally come across this before!

     

    There's a good site here for advice on laptop batteries that may help. It will also be worth checking Acer Support on the Drivers & Manuals page for an update in BIOS. Just be cautious that flashing BIOS incorrectly can render your laptop useless!

    Hi,

     

    I upgrade the latest bios version, but the situation has not changed. Is this case can be solved if I reset my lap to factory default (both window and bios)?

    Yes, it is certainly a possibility. Try it and see. It would likely be the first thing support would suggest!

    Let us know how you get on!

    I restore the lap to factory default. The notification of battery (fully charged) just show: fully charge (100%), but does not show that whether the battery is still charging or not. I think I will take reference from the site you advised for more information.

    Thank you for your support.

    I just checked the battery by batterybar, the software shows that wear level is at 3.74%. I've been using this lap for about 3 month. Is it normal? I do not use it intensively,

    3.74 isn't too bad. I'd say that is quite normal!
