Oops. The above link to the Extensa 50x-510 Service Guide was incomplete. Here's the real link:
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.

First you need to remove the keyboard to gain access to the CMOS battery (Acer call them a RTC battery)
Tell you what give me a email address and I'll send you the service manual.

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.

The computer locked and I can not unlock because it won't let me type inn my password. no letters appear when I type. Acer extensa 4620-4431

For security reasons, some laptops do not show passwords when you type them on the password page.
For your own case however, I would suggest that you should just try and reset the Laptop Password to its default settings by removing the CMOS battery. This means you might have to unscrew your laptop at the back, and try to locate the CMOS battery, remove it from a few seconds and replace it. This method will automatically reset your password to its factory settings.
If you cant unscrew your laptop by yourself, you can easily get a technician to do it for you.
Hope it helps you out.

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.
