Acer wireless switch turning itself off

Acer / Aspire 3935
July 11, 2010 at 10:10:45
Specs: Windows Vista
If I put my laptop (Acer aspire 3935) down and pick it up again, or if I even change its position on my lap, the wireless switch switches itself off. The only remedy is to 'sleep' the computer and then turn it on again. Any idea what's causing it?

See the Owner's or User's manual for the model. If you still have the original brand name software installation, that may already be there in your Programs list.

If you have reloaded Windows on the computer from a regular CD, Windows may not have the proper info about how the mboard's ACPI features (Standby, Hibernate, etc.) are supported by the mboard, until AFTER you have installed the main chipset drivers for the mboard in Windows.

If you have loaded or re-loaded the "drivers" for the wireless network adapter yourself, you may not have loaded them properly.

Unless the instructions for installing a device tell you otherwise.......
You DO NOT install drivers for a device while booting into Windows, if the software for the device has not been installed yet - when Windows detects a generic device or New Hardware while booting, you allow it to search for drivers, it doesn't find any, and it wants you to show it the location of the drivers - CANCEL that, continue on to the desktop, and install the software for the device using the proper installation from a CD or the proper installation file that you downloaded from the web.

If you DID install drivers that way, go to Control Panel - Classic View - Add/Remove Programs and Un-install the software you installed, reboot, DO NOT install drivers while booting, and install the software the right way !

The same applies no matter when Windows finds New Hardware !

I haven't done anything to the computer since I bought it six months ago. Nothing new has been's as it was. Apart from a USB pen drive which is very rarely used, nothing has been plugged into it, either. I use it to access the internet, and that's it.

I'm very much a computer novice, so if I've misunderstood something, I apologise...and please let me know what I should do in the simplest terms you can manage! Thanks....responses are much appreciated.

Read the
Quick Start Guide
for your 3935 model series.
You may already have this in the Programs list somewhere:


Page 4, 5

There is a button above the main keyboard that toggles the wireless on / off.
Make sure you're not pressing that un-intentionally.
If the wireless goes off, try pressing that to toggle the wireless back on.

If that doesn't help
- if you're near the limit for where you're getting a good enough connection to the internet from a nearby wireless device , you may lose the wireless connection at any time, especially if it's wireless G rather than wireless N, such as when you move the laptop a short distance. Putting the computer "to sleep" then "waking it up" again may or may not make the wireless connection work again.
There is often an icon in the Taskbar bottom right corner of the desktop screen - it may be hidden, and you may need to click on < there to reveal it - that shows you the strength of the wireless signal, e.g. vertical green bars. If there are, say, only 3 or 2 green bars showing out of 4, you wireless connection may be "iffy" and it won't take much for you to lose the wireless connection.
(If you don't see an icon similar to that, you can change a setting to make it appear.)
- move the laptop closer to the router or other wireless device that it connects to
- apparently ( it says in the Generic User Guide manual listed for your model) the laptop has two wireless antennas in the lid above the display, but only one is used at a time, whichever one can establish a better wireless connection.
When you move the laptop, you may lose the connection to both antennas. You could try rotating the position of the laptop a bit.

There's no problem with wireless reception - the signal is really strong. And I'm not inadverently touching the wireless switch.

It seems to be any change in the position of the laptop that does it. Putting it down and picking it up is a problem 90% of the time...hoever carefully and gently I do it. And changing the laptop's position on my knee is a problem maybe 50% of the time. And I'm touching nothing but the sides of the casing of the keyboard.
It's weird.

Oh...and pressing the switch to get the wiireless back on again doesn't just flashes on and off and ulitmately off again.

The only other thing I can think of is there is a loose connection inside the laptop.

If this has NOT done this since it was new, have you dropped the laptop, or is it possible someone else has dropped it?

If it HAS done this since new, or in any case, you could take it to a repair place that's certified to work on Acer laptops and have them check it out, before your probable 1 year warranty expires - that will be covered by the laptop's warranty if it's been doing this since new, or if they detect no evidence that it was due to whatever the laptop was subjected to since by you or whoever.

Laptop warranties don't cover accidental damage unless you purchase extra protection that covers that when you buy the laptop.

Your input is welcome, but I doubt sarah55 will see it, since she has posted only about this one topic.

The antenna for the wireless network adapter is in the lid above the display or behind the display. A thing that can cause this problem is damage to the wiring that passes through the hinge area from the base of the laptop to the lid, but usually that only happens after the laptop has been opened and closed a lot for years.

"Would a newcomer be warmly welcome here?"

Yes, but if you want to post about something other than the subject of this topic, or about other than this model, you should start a new thread - "Start a discussion".

The busiest forums on this site are probably Hardware (General Hardware), Windows XP, Windows Vista, Windows 7, in that order.

"Good day you guy !"

You can edit your own posts on this site ( except possibly the first one in a thread, if you started the thread, after at least one response has appeared) by clicking on the notepad like icon at the top right of your posts.

There is a limit (days since first posted) for how long you have to post in an older thread, or edit your own posts - after that limit you can still read it but you can't add a post to the thread, or edit your own posts in it.
