Random Shutdowns Aspire 5733Z-4851

“Random Shutdowns” for various Aspire Laptops.
The problem may or may not have anything to do with loose screws or BIOS updates.
Try replacing the 2032 battery located inside on the motherboard.  I think this will solve the issue.   Since changing the battery I have had seven hours of uninterrupted keyboard time.   Batteries don’t last forever and I had over 21 years in the IT industry repairing computer systems.

Thanks for sharing this information. I'm also wondering how many volts did the old battery measure ?

This Applies to Various Acer Model Laptops.  Mine is an Aspire 5733Z-4851.
I am sure this simple fix will work just like it did in the old days when the BIOS info was held using a AA battery.

Hi @Tjames1952,

Try to do power drain,

1. Turn OFF the unit.
2. Unplug the charger. 
3. At the bottom there will be a tiny pin hole with battery sign close to it take a pin or paper clip and insert into it hold that button for 20-30 seconds. Then turn ON the unit and check.​

My model of Acer Aspire 5733Z-4851 does NOT have a battery reset pinhole either through the frame or on the battery.

To Larryodie,  2032 disc batteries carry a 3 volt charge.
When I checked the charge on the battery that I removed it was down to less than half of that.
