Harddisk Security Code - Acer Aspire 5720


I'm trying to fix my friend's daughter's notebook as when you turn the PC on it comes up with the following message:

Primary Master ST9160821AS SET

When I click enter it asks for a password but I don't know what it is! My friend's Daughter got the PC for Christmas & as she is only 10, she can't remember what it is - can anyone help? I only want to reboot the system but it won't let me do anything without the password.

Generally you can remove passwords by removing something called the CMOS battery. This battery retains the configuration of the computer when the AC power and main battery aren't present or working.

The battery is generally located in the RAM expansion bay. Locate the battery and remove it. let the laptop sit without ANY power connections for at least 30 minutes. When 30 minutes or more has passed, replace the battery and connect power. Boot the laptop and press F2 to enter the BIOS setup. Generally no configuration is necessary on laptops so just save and exit.

Hi Zain,
Actually even if your notebook does NOT have hard disk I can assure you Zain that your notebook WILL boot (POWER ON)

Base on your explanation Zain there is a Possiblity that the problem is the charger of your notebook (24hours overuse) try to ask your friends that has the charger of you notebook and try to check if the notebook will work using the another charger.
If ever your notebook will not work , reason will be one of the hardware parts inside the notebook needs to be fix.

My advice for you Zain is to bring your notebook to the nearest acer support center in your area, you can also check the location where is the nearest support center by visiting the website of acer.

Acer Aspire 5720 Laptop issues.

It could be the battery. So i'd try to find a store that sells batteries and replace the battery.
Manny laptops will shut off when the battery is dead. So if your laptop works without the battery and only connected to the wallsocket, it's definitely the battery.
With kind regards,

My computer won't start up. I have tried all the available diagnostics on the Acer notebook.

I used the suggestion given to use chkdsk/r. I couldn't access it the first day, however, the next day I used this option and after 3 hrs., my daughter's laptop windows was restored. Thank you!!!
