Question about Acer ASPIRE 4520-5141 AMD TK-57 1.9G 1GB 120GB DVDRW 14.1-WXGA WL WVHP PC Notebook
There are 2 ways you can reset your bios.
1. On the motherboard there is a small watch battery. Remove this battery along with the power cable from the power supply. Hold down the power button to fully discharge the system. Wait 2-3 minutes then reinstall the battery and plug in your system. Your reset is now complete
2. Some motherboards have a 3 pin jumper by the battery. Lets say that the jumper is on pins 2 and 3. Remove the jumper while the machine is OFF and place onto pins 1 and 2. Power on your machine for a minute. (Note: Your system will not POST). Shutdown your machine and put the jumper back to pins 2 and 3. Your reset is now complete
This is a great troubleshooting step for those of you having POST issues or no POSTing at all. Like other troubleshooting steps, this will not always work but usually will depending on the problem.
Please let me know if you have any further questions or concerns.
