I bought an iPAQ 3135 and all the accessories at a garage sale. I have no warranty, but that's ok, for $20. It works ok when plugged in, but the battery won't stay charged. I charged it overnite twice, but the battery only stores enough juice for 5 minutes after pulling the plug.
I have the OEM CD, but no hardcopy manual.


How best to obtain a replacement battery for iPAQ 3135?

Should I buy one and replace it myself, or should I have have HP service it?

Do I need the manual?

Is the manual on the CD?

Can I access the manual online?

Where can I get a hard copy of the manual?
