Resolved can an old laptop battery prevent normal startup

Toshiba Satellite A75

Been a week of BSOD, and black screens. Removed the battery, plugged into AC, now it starts up. Three or four times of normal start up.

Because I can't believe it is that simple, have installed the same battery, and it starts up normally, BUT it tells me no firewall is turned on, alternating with "your anti virus software is out of date ".

Have run AV, MBAM, all is clean. This is on a clean install of the operating system and all updates being installed.

 

Forgot to add:

This computer is used often, then shut down and unplugged

 

Still stinks of malware to me...

When did the BSOD's start? Before or after the "clean install "?

How did you do this clean install?

If it's not malware I'm suspecting memory or Hard Drive.

Please use SIW to complete your system details and we can take it from there.

 

figured it out. Left it unplugged overnight, same BSOD, plugged in for an hour or two, starts up.

 

I don't understand that logic.

 

You may have a bad connection from the charger to the Laptop connection. As Wildfire has suggested - complete your System Specs and this may help with further diagnosis.

My Laptop is not plugged into the mains until I use it - maybe days. It will start on battery and run perfectly - with or without AC power.

You may have to Post in the Malware Section as Wildfire has also suggested.
Why did you do a reinstall of OS???
What problems were you having before???
