Go to this link to show how to roll back the keyboard.
Once you have done this then to your left you have the heatsink it has 4 screws in, undo the screws and you will see the Cmos battery just pop it out and fitt new on . Make sure u earth yourself before going into the machine HOPE THIS HELPS

Oops. The above link to the Extensa 50x-510 Service Guide was incomplete. Here's the real link:
http://www.mmicro.it/cmp_img/esplosi/extensa/extensa500-50x-510.pdf
Note: you have to remove the CPU heat sink to get at the battery. Not sure you can just put it straight back on after replacing the battery or if you have to use a new heat sink pad? Looking into it.

If you want to do it yourself check out the following links:
Search for "Removing the RTC battery" in the following document:
http://www.mmicro.it/cmp_img/esplosi...00-50x-510.pdf

The pictures on how to fold the keyboard back are easier to see in the following link :

Each time I start my eeepc 1005HA, time/date has gone. This sounds like a CMOS battery dead. I expect you give me what I must buy and how I can replace the battery. Thanks a lot.


you should change your cmos battery. the model is ML 1220. don't buy the CR 1220 because it is not rechargeable. I hope this helps. I also have the same problem with my asus eee pc 1005HA.

I only get a key symbol when it starts up


My suggestion would be to try flashing (reload) the bios. You should be able to find a utility from your PC or motherboard manufacturer's website that allows you to create a bootable disk for this purpose.
