Acer Aspire 5742 :: Unauthorized Windows 7 Message
Jan 23, 2015
I have an Aspire 5742 factory loaded with Windows 7 and it worked for 3 years. Now, Microsoft is sending me 'Unauthorized Windows' messages. The hardware has not changed. Microsoft checked and said my OEM product key is fine. Restoring to a previous point failed to fix problem. I just ordered the eRecovery DVD. Is there a way to fix this without wiping the system and starting over? I have a LOT of software installed that I will hate to lose. BTW - my best guess is that malware caused this.

I bought this Z710 new but I get a message saying "The battery is unauthorized". Also the battery indicator stays at "0% available (plugged in, not charging)." If I unplug the power cord, the laptop powers off cold. It has always been this way. This is a problem for me because I want to upgrade my BIOS but I can't because I get an error stating "Battry is too low (0 < 30 ). Please charge your battery to 30%." when I try.
How do I get this laptop to start interacting with its battery? I have already tried taking it out and putting it in again and rebooting.

I own an Acer Aspire 5742, model no. PEW71. It is running on Windows 7. I included a vid for you to see what the problem is: [URL] ....
So, as you can see, the computer can be turned on, but it doesn't get through the acer screen on to the windows picture, and it automatically reboots and shuts itself down again over and over again. This has happened in the past, but the repairers have reset the operating system and BIOS. They also switched the hard disk for a new one, but this could be because of some other problems I was having (USB channels weren't working).
Everything worked fine for a month or so, and then it happened again. I myself am thinking about the motherboard being damaged.When this happened in the past however, I was still able to turn on my PC sometimes, so I was also able to save my files. Now on the other hand, I can't get the computer on anymore. The most important thing to me is saving the files. After that, I'll take it away for reparation again, where they will probably delete everything again (I can't commicate with the repairers myself, so I can't discuss terms or anything).
At the end of the vid you can see me turning off the computer by pulling out the adapter. Removing both the adapter and accu is the only way the computer can be turned off. Even shutting it down by pushing the on/off button for 5 seconds will not prevent the auto re-boot.

At some point during the day, the sound on my Acer Aspire 5742 (running on Windows 7) ceased to function. There is no sound on any internet browser, and the normal notification audio is also not playing. I have checked the mixer and everything is fine. I have checked the speaker properties, which says that the Realtek Audio speakers are enabled and working properly. However, when I try to test the speakers a message says 'Failed to play test tone'. The weird thing is that Spotify is playing totally normally. I have tried shutting down Spotify and restarting it. I have tried turning my computer off and on again.

Got an acer 5742 running windows 7. All of a sudden the display has stopped working.
It boots fine and the display works up to the point of "starting windows". I see the windows logo for a bit then it goes off.
If I plug into an external display it works fine. In graphics properties, the display isnt even listed (only the external display shows up).

I'm sure I have a virus that won't let me do a full scan on Windows Defender (only quick). It won't list ACER's eRecovery option. How may I do a factory reset? This is an ACER Aspire 5742-7653.

I have an Aspre 5742 which is a couple of years old now. It is running Windows 7. I have been trying to output the display to my TV but it is not working.
When using the HDMI connector there is no output whatsoever. I have followed the suggestions on the Acer website about detecting connected monitors but this does not detect my TV ...
When using the VGA output the deTect function detects the presence of the TV but the TV does not detect the computer.
I have connected another computer to the same TV using the same cables (HDMI and VGA) and everything works just fine.
I have updated the video drivers on the Acer but there is no change.
A few months ago we had to change the hard disk as the original packed in. I put in the same model disc as I took out and reloaded tyhe software from the rescue disc. Prior to this the HDMI worked perfectly.
TV is a Sony Bravia

I'm reformatting my HD and it gets stuck on 31 of 32 in the cleanup stage. I had this happen last time I did a reformat but I forgot how I fixed it. I have an Aspire 5742 using Windows 7.

I have been using this small utility for caps lock on a 5742 using W7 Pro and it works well. The 5742 doesn't have a caps lock light or indicator built into from Acer, so one have to come up with something.
This program will place a red "x" or green "check" in the taskbar letting you know if you're in caps lock and will also produce a small "beep" after a few letters typed in if in caps lock.

My Acer 5742-7653 is stuck in reboot loop. It starts to load Windows 7, and then the screen goes black, and it beeps a bit, and theen starts over again. The F2 button no longer gets me into Setup. And the F12 doesn't work. I can't get into SafeMode or Setup. When the problem first began, I could sometimes get into Setup and boot from an external HD which as a diskImage.
I used to be able to remove battery, and remove HDD and RAM, and then it would boot up from the external HD. To get through a busy period at work we set the power option so the computer would never shut off. But this is creating problems with all the Firefox, Adobe and Windows updates that want to run.
This is running on Windows 7, 64bit.
How can I determine if this is a problem with the HDD, or the RAM? or Motherboard? What else could it be?

I've had my netbook for a few years and this error message has been appearing bottom right since I got it. Both USB ports have always worked fine. Device manager it shows a USB controller as not recognised by Windows. f I try to 'update' it says wndows doesn't recognise it. I can disable it but of course it renistalls on reboot and the message starts again.
I ignored it as it didn't do any harm. Recently I did a factory reset expecting this to do the trick but it didn't. I also updated the bios to v2034 I think but there's not much content to it so I've not got any USB options there.
I'm wondering if there are chipset drivers I need to get, though the Acer site doesn't offer anyting new there.

I hit enter eight times, and I get a choice of entering a password or continuing, when I continue I can go on to windows. If I choose enter a password I get a blue window with a KEY. I can take the eight digit number key, and enter it in a program on another computer, 'allservice.ro/acer' which gives me the password. I enter the password into my laptop (acer aspire E1-531-2438) and it leaves the blue window, and I can continue either with the HDD loading windows 7, or I can load a cdrom or dvd.
This is great. But if I reboot, and hit F2, I enter the BIOS, and choose security, and I see that the HDD password is still set. If I hit enter, I can enter the HDD password, but when I enter the one I just used, it tells me it is invalid.
I have also tried to kill the power, and startup again going into BIOS, but the HDD password I just used is still invalid.

I've had my Yoga 2 Pro refurb, purchased from Best Buy, for about 3 weeks now. A couple of days ago the Lenovo Energy Manager app started showing a warning about an unauthorized battery being installed. And just now its telling me that the power supply is not authorized and that the laptop cannot be charged.

I recently updated my bios and decided to do a new full install of Windows 7. (Previously running Windows 7 Beta).
After doing a clean install and installing the Sony Notebook Utilities. I started getting this pop up message.
"The installed battery may not be properly connected to the computer or may not be compatible with the computer.
Click OK to enter Hibernate Mode, and remove reinsert the battery
See the electronic VIOA(R) User guide for more information about using the battery"
At first I thought this was an issue with Windows 7 - so after searching the forums and no results I figured I would revert back to Vista. Now I am getting the same error.
I also have two Sony Notebook batteries here - both bought direct from Sony. One extended and one standard - both give same error message.
Could this be a BIOS issue? Is there a way to revert to an older bios?

Several years ago, I bought a HP G71-340US notebook with Windows7 (it was a refurbished model directly from HP). I have used it for mant years without real problems until last week. I am now getting on the bottom right side of my screen "Windows 7 build 7600 .This copy of window`s is not genuine" message . This is the same version that I bought from HP, though I have periodically updated Windows7 with Microsoft's updates. I called Microsoft and they told me that I either needed to purchase the software again or give them my access code from the discs, which I didn't receive from HP. What can I do to either get it to work or fine the Windows7 installation code?

I have 12 updates showing as needing to be installed in my windows update to go onto my new lenovo G500 but every time I try and install them I get the error message 80242006. I have googled it and tried the suggestions with no luck although I have yet to spot one that is for windows 8.1 which I have upgraded this laptop to.
The missing updates are KB's 2987107 ,2968296, 2972103, 2979573, 2978041, 2979576, 2977292, 3000061, 3000869, 2989542, 2998174 and 3000988.
Could the problem be because I have upgraded the laptop to windows 8.1 from 8?

I've tried clicking Yes and No with no permanent lasting improvement!!

I have an acer aspire 5610 and am having a problem. Everything was working perfect then randomly one day it went black. When i log in it still has the windows sign and everything but when i am in the desktop it is black there is no start bar or Icons or backround. Basically my GUI is gone. but i can still see my mouse pointer. I found that i can run programs by opening task manager and clicking file and start new task then browsing on what used to be my desktop for the internet icon. this works and everything works as it should. but i get an error message fo most all programs other than internet.
i have attached screenshots of my desktop and of the error message that pops up.
at this point i dont care about salvaging the stuff on my comp just want to reset it back to factory defaults. I have tried recoverry CDs that were made and it doesnt recognize them, i cant get to eRecovery due to the error message
