Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
When you purchased that computer, did it ship with windows 8 or 10, or windows 7 or below?
This is an important distinction as it will let us know whether the BIOS uses CSM / Legacy or UEFi
Understood. What happens if you load in battery power.. Wait to be fully loaded, and then plug in the AC cord.
Also, are you sure you have the 6935 and not the 6935G ?
Thats a problem.. D efinitely a bios error and not the power cord.
The problem is, even if you download the bios from this page http://www.acer.com/ac/en/US/content/drivers
It almost always will tell you that you need to plug in the ac cord to install the bios, you could try ( but dont plug in the ac cord as we dont want to crash the computer during a bios update )
next question, if you remove the battery, and the power cord, and press and hold power for 30 seconds.
And trhen plug in just the power cord ( not the b attery )
Can you boot that way?
You have linux loaded on a USB ?
Have you tried loading an OS on an internal hard drive and seeing if you can boot that way?
Ive tried to type t his message three times now.
You can attempt the bios update using just the battery, but if it asks to plug in the Ac adapter, dont do that.
On a side note, have you tried inserting the vista hard drive, and booting while using the ALt F10 recovery function?
My thought process is this.. Maybe doing a simple ALT F10 factory restore on vista would allow us to use the power cord long enough to run the bios update.. And that may solve the issue and allow you to run on AC power from a USB drive as the boot source.
Also, the bios update most likely was written as an exe file, more easily ran from windows in most cases, rat hen then linux / ubuntu
and it could very well be a motherboard issue ( the bios being part of the mot herboard ) or it could even be the DC jack failing ..
Most often though, what you described is a classic bios failure issue..
Its not imperative, and the update is usually less then five minutes.
The issue is, t hey build an ac power check into the bios flash tool, so it checks if ac power is available before allowing the update. ( about 90% of the time )
The factory restore procedure is pretty easy.
Shut down the computer, start it and immediately press and hold the ALT key and the F10 key.
You have to press those keys in the first half second after pressing power to start the computer, and hold them.
Sometimes, you have to hold ALT and rapidly tap f10..
It sometimes takes 4-5 tries to load into the acer recovery partition but once you do, the rest is just a few clicks to tell it to restore.
Take your time, Ive still got 4 hours on shift today.
All right, keep me posted.
You can only trigger ALT and F10 , when you very first press power. ( its like a bios key, you only have a very small window to hit the keys )
Sometimes, you have to tap F8 instead and choose repair your computer, and then go for the full system recovery that way.
Question though.. Is it running on AC power with the hard drive installed?
Couldnt hurt to try system restore.
Then see if it gives a system recovery option.. if its only system restore. Then go back to the oldest date you can see after clicking show more or show older restore points.
Im not sure what else to add. Seems were stuck in a situation where we cant upgrade the bios, and even then if its a mainboard issue outside of the bios, wed be out of luck.
Im not sure whether you would consider it worth it or not, but you may have to dissemble and replace the mainboard.. As that would fix the Power issue.

System image recovery is what we want..
As far as flashing the bios in linux, youve still go the no ac power issue in linux yes? In which case the bios wont let you flash it ..
The motherboard would definitely solve the issue. Just make sure to order a small tube of thermal paste for the cpu, as when you remove your current cpu from the current motherboard you will need the thermal paste to attach the heatsync to the cpu in the new motherboard.
If its not showing the acer system image.. T hen the recovery partition must be missing or damaged..
end of the line for that process..
If the system restore goes through correctly. Theres always a chance that the computer may boot )( after one more startup repair )
Lets not run system restore again.
Instead.. Lets try to download and run the bios update.. Maybe well get lucky~
Lets try the following
Go to Device Manager/System Devices and uninstall ACPI Power Button and ACPI System Button. If there is a listing for Advanced Power Management Support, remove all listings for such. You'll be prompted to reboot after removing each, during restart Windows will reinstall the driver for each
The wireless adapter may need to be right clicked and enabled from the device manager.
Or, the driver may need to be reinstalled from the acer site.. Hard to tell this early on, and with it not booting in quite some time..
All right.. Restart after the uninstall.. And continue looking for anything ACPI or the Advanced power management support
Allright.. It should have enough time to finish before the battery gets low..
Looks like it should finish before the battery runs out..
Race against time eh?
All right.. Im assuming that the power cord still shuts the machine off..
Or have you tried it yet? ( with windows running )
My apologies for the delay.. weve hit the end of my shift.
Id go ahead and attempt to plug the power in, and if that doesnt work.. Charge the computer and we can try to continue tomorrow or later in the week.
Hello again, and my apologies for the delay in getting back to you.
Glad to hear all is well.. Reinstalling the power control system devices through the device manager must have done the trick!
Since it can run off AC power, id strongly consider that bios update now.
With that being said, when you can please dont forget to return here and click and submit a star rating, as currently this support session shows as unsolved, with no help given.
Ahhh.. Windows updates... Heres my advice.. When we get the machine running this time, completely turn off windows updates.
As clearly one of those updates is causing a severe issue.
Id say yesterday or last night if its showing.. Right before the updates tried to install.
But worst case scenario go back to the earliest point you can, and we can walk through the repairs again from there
Hopefully that was before the windows updates started.. That way, the work we did to get the AC power corrected, will still be intact.
Then, just make sure you go into the control panel, windows update, and tell it to never download or install updates
All right.. Sounds like a plan..
Id allow chkdsk to complete, and then.. Let it run a startup repair if needed.
Then, lets try an F8 safe mode start.
If were in windows 7.. Lets not reboot.. Instead..
Go into control panel, windows updates, and completely turn them off.. Set them to never download or install
Then, go to the device manager.. And lets start looking for these items and uninstalling them
look for anything ACPI or the Advanced power management support
Ideally, if we repeat the same steps as before, we should end up at the same result
I strive to provide great service, and greatly appreciate a 5 star rating clicked and submitted when you are satisfied.. I always answer follow up questions.Dustin S.Senior Technician and Network Switching Systems Operator / Maintainer.
Lets go with power button.. Lid, and fixed feature button.
When you uninstall, do not click the button that says uninstall driver too..
Afterwords, restart .. And let the device startup.. Then, try plugging in the ac power and lets see what happens.
Also, now that the computer is booted and online.. Remote support is also an option..
Question.. did we remove the devices, restart, allow the computer to fully start.. And then plug in the power cord?
Or, did we plug the power cord in before windows started?
Perfect.. Bios update time..
Make sure to choose your current OS, then bios. Then download the bios update.. Open it, and run the setup or exe file inside.
Then, just let the computer reboot or do its thing normally, and do not interrupt it
Ahh.. Go into the device manager. Go to network adapters, what do you see?
And if you right click each one, is there an enable option? If you see enable, enable it.. As that may be all you need to do is enable the wireless adapter.
Otherwise, just plug in the ethernet cord directly to your router, and youll be online.
Ok, so you have both the ethernet and the wireless adapters.
Lets try this.. Restart the computer normally, click windows, power, restart.
lets keep the ac cord removed for now.. that should get us back into safe..
And then, we need to run a cmd line repair, sfc /scannow
exit out.. remove the battery.. press and hold power for 30 seconds.
Boot with just the battery..
After you press power and hold it to force a shut down. Wait 3 seconds, then start the machine and immediately start rapidly tapping the f8 key..
Does that bring you to the safe mode screen.. If so, make sure you choose safe mode with networkiing.
And id repeat the above a couple of times till it lets you into safe mode.
launch windows normally and then immediately start tapping the f8 key.. Safe mode options?
If not, run startup repair.. ( whats clear is the boot sector is pretty badly corrupted, hence the issues were having)
May want to consider getting a windows 7 iso, creating a valid install disk. And then formatting the hard drive and clean installing windows.
safe mode with networking, as stated before..
Once your in, lets see if we can get net access.
when you try safe mode and it hangs up on any file.. Write down the full line of t ext that it stops on, word for word.
That will tell us whats stopping windows from loading
AVg is causing the issue.
When we get back into safe mode.. We need to try again to uninstall AVG.. Hopefully if we can connect the ethernet with safe mode and get in.. We can download and install a program called revo uninstaller, which can do a full removal down to the registry level, of AVG..
Since AVg is whats blocking us from booting into windows ..
Do you have a mouse that you can plug in, usb?
Lets not restart. Instead, maybe its time we move to a secure remote session, So I can connect and work on repairing some of the problems directly?
Yes.. but use the revo uninstaller program, and after you click AVG to uninstall it inside revo.
Click the advanced button.
All you need is the free t rial, dont purchase the program!
you have to install revo..
And t hen open revo.. And inside of revo, double click avg.. Start the uninstall.
Once it runs through or fails the normal windows uninstall, you will see a pop up screen with three options.. Click advanced or the far right option and have it scan for leftover files.
Select all and delete, scan again, select all delete.
Then, AVG will be gone. Try restarting the computer and seeing if it boots normally.
If not, try safe mode and see if it gets stuck on a different file .. If so, report back what it is and we will go from there.
Is there a next button that highlights when you click advanced?
try clicking different bubbles, and switching back and forth and seeing if scan will highlight
If it already uninstalled AVG ?
Then cancel revo.. Restart and lets see if it hangs on a a different file or boots
Cancel out of the scan window.
Close avg and open it.. Is AVG still showing?>
IS AVG st ill showing in REVO ?
I have to take a short break.. I skipped lunch and dinner is due.. So ill be back in half an hour.. I wont be able to reply before then
Choose advanced, and start with one avg program. And then after its complete.. See if it still finds others.
if so, repeat advanced, scan, select all, delete.. for each avg listed
Locate all those files in your windows / system 32 folder.
And when you find one right c;lick it and rename it to avg*8etc*8 .old
Its only the end of the file name you need to change to .old
Another reboot, should let us know.. ( there could be a myriad of other issues, but we could get lucky and that may be the last roadblock )
keep me posted as to what happens when we reboot
In safe mode, open an elevated command prompt.. Or right click the command prompt and run it as an administrator
Then, copy and paste this command and hit enter
rename c:\windows\system32\drivers\classpnp.sys classpnp.old
Reboot.. Still hang at class pnp?
All right.. Standing by~
Lets hold off on the bios update till we have a handle on the various errors.
Lets go back to the command prompt, and run this command
Once it completes, reboot and see if we get stuck on any files during a normal startup
Question.. Are we running in safe mode, with the AC adapter.
If so, its time to go to the acer support site for your model, and download the bios.. And time to try installing it.
All we should need to do..
Is double click the zipped folder.
then inside of it, should be a setup application, or setup exe file. Double click that, and then it will go through the install process on screen, you may have to click next, ok, etc..
extract all, watch the folder path.
Then, once extracted open the extracted folder and find the setup exe file.. or setup application
And windows is the one inside you want
This is the one we want
it could be.. also, you may need to right click inside flash, and run it as admin
The folder must have extracted incorrectly..
Being that Im not there, its hard for me to say what happened.
You could start at the beginning with the zip folder, right click the entire folder.. extract it.
Then, open a new window and go to the extracted location. Then, run the insyde flash program
Understood.. Maybe it would be best to setup the remote connection for later tonight.. Or tomorrow?
if you have to leave in 30 minutes.. Im not sure if wed be able to connect and run teh update, and even if we could.. Wed still get cut short before we could run through further repairs.
Ive sent the offer to you, at the standard value. Its not mandatory that we go into remote ( though it would cut down on the time t o completion substantially_)
I will keep an eye out for your replies tomorrow, or later tonight.
All right Steve.. Ill be working till midnight ( 5 more hours )
So Ill leave it up to you to contact me, and let me know when you want to continue.
