How To Factory Reset a Fujitsu Siemens AH530 Laptop


Step 1 - Install Windows 7 Home Premium

Step 2 - Activate Windows using the Certificate of Authenticity stuck on the bottom of the laptop, at the time of writing this is still possible, but only over the phone (I tried to do it online but that did not work)

Step 3 - Install the Drivers and Fujitsu Utilities

Step 4 - Install the Windows 7 Service Pack 1 update

Step 5 - Install Windows Updates - I'm using WSUSoffline to install the Windows 7 updates that I have downloaded previously

That's it!

How To Replace The CMOS Battery on a Compaq Presario 700 Laptop

Step 1 - On the bottom of the laptop, remove the two torx headed screws holding the bezel in place that gives you access to remove the keyboard

Step 2 - Turn the laptop back over and use plastic spudger (or carefully use a flat blade (slot) screwdriver) to remove the plastic bezel holding the keyboard in place

Step 3 - Carefully remove the keyboard and then unscrew all the screws as indicated in the photo below

Step 4 - Carefully remove the metal cover to reveal the motherboard, CPU and optical drive

If you look closely you can see the CMOS battery hiding above the optical drive:

Step 5 - Disconnect the CPU fan and place the metal housing to one side and then carefully flip over the laptop and remove the 2 screws holding the optical drive in place

Step 6 - Turn the laptop back over to gain easy access to the CMOS battery!  If (like my laptop) there is a cable in the way of the battery, unplug it!

Step 7 - The button cell/battery that you need is a CR1220 - luckily I have a wide selection of button cell batteries so I was lucky to already have one ready to use...

Insert the new replacement CMOS battery in to its holder

Step 8 - Plug back in any leads you unplugged, insert the optical drive (and screw it in to place), reconnect the CPU fan and screw the metal cover back in to place, connect the keyboard, clip the bezel back in to place, flip the laptop over and screw in the remaining screws

Step 9 - TIME TO TEST (pun intended) - turn on the laptop and press F10 to enter the BIOS

Step 10 - Set the time and date and then Exit and Save from the BIOS

Step 11 - Power on the laptop and boot in to Windows!

BINGO!  It now boots without any CMOS battery errors :)

Replacing The CMOS Battery on a Dell Latitude D630/D620

Step 1 - Unplug from the mains and remove the battery

Step 2 - Remove the hinge cover (make sure the screen is flat when you do this)

Step 3 - Use a plastic spudger (or carefully use a flat blade screwdriver) in the notch on the right-hand-side of the hinge cover to gently remove it

Step 4 - With the hinge cover removed you can now unscrew the keyboard:

Step 5 - Carefully remove the keyboard and the CMOS battery should be revealed.

Step 6 - Once you have replaced the CMOS battery (it's basically a CR2032 by the way) all you have to do is reverse the above steps and you'll be good to go!

Make sure you press F2 to enter the BIOS and check/set the date and time after replacing the CMOS battery as it's this battery that keeps the RTC (Real Time Clock) going when the laptop is powered off.
