Windows 7: Wireless Internet disconnects when i close laptop lid

Wireless Internet disconnects when i close laptop lid

Hi, I have Lenovo B570 with windows7 installed. To avoid internet disconnection problem, I changed settings in Control Panel as follows:
In Power Options, then in advance settings I selected options "Do Nothing" When laptop lid closes...
It resolves my problem partially... After closing the lid if system does not get lock then internet connection works fine but if system goes to lock state (this happens when lid closed time is more than 20 mins) then after login, the internet connection is visible as disconnected.
Any suggestions?

Are your drivers updated to the newest one avaible ??

Also you can try disabling this:

it's in dutch but I think you know where to find it

Device Manager > select your Network driver > and do what you see in the picture (but ! disable it)

Well for the first problem re-read my first post (I edited it)

for the second problem I would try this:

- Let the battery go to 0% so save your work (because it will shut down)
- and try then to plug in your AC Adapter and see if it charges or not. (if it doesn't charges then maybe your AC Adapter broke down (so to test that you can try to pull out the battery and power on the laptop without the battery and with the AC Adapter if that doesn't work than you have a bad AC Adapter or there is something wrong with the laptop it self)

Hi azeem12, welcome to 7F, and Happy New Year!

I would advise not to take your battery down to 0%.
Quote:
Caution should be exercised not to discharge a lithium-based battery too low. Discharging a lithium-based battery below 2.5V may cut off the battery’s protection circuit. Not all chargers accommodate a recharge on batteries that have gone to sleep because of low voltage.

Source: Chapter 5: Discharge Methods
2.5v on a 4400mah battery equals 5.68%, so anywhere between 5, and 10% would be okay.

Then follow GianniDPC second step.

Thanks Anak for giving useful precaution.
I resolved battery charging problem from this link:
Plugged in, not charging Windows 7 solution : Jeffrey Palermo (.com)
Now battery is charging. But i am little worried that why this problem occurred? Do anyone have any idea about reason of charging problem???
After performing steps in above mentioned is there any guarantee that this problem will never rise again???
One more thing, is it necessary to disconnect AC Power once battery fully recharged?
Please reply to all questions, i ll appreciate.

It is a power managment for batteries device driver problem.

azeem, life does not offer guarantees. there could be mutiple reasons why that driver could become corrupt again.

No, but it is cheap insurance to do so.

The battery management program problem you solved by re-installing the driver should be smart enough to determine that the battery is sufficiently charged, and shut itself off until it is need for the next charge, but why take the chance. You do not want to overcharge a battery either.

A normal Li-on charger/battery should not get warm at any point in the charging/idle mode. If it does it is defective.
