I hold an emeritus compaq presario 1235 laptop.The battery dosn't clasp the charge can the battery be replaced?

YES YOU CAN GET A REPLACEMENT BATTERY FOR THE PRESARIO 1235.THEY ARE SUPER CHEAP AT WWW.KAHLON.COM.I BUY FROM THEM QUITE FREQUENTLY AND THIER PRODUCTS ARE A-1 AND THEY ARE COVERED BY A ONE YEAR WARRANTY.AS FAR AS MEMORY,THE 1235 IS SIMPLY LIMITED TO 96MB OF RAM AND ONLY HAS ONE MEMORY POSITION.YOU SHOULD RAISE TO A NEWER LAPTOP AND KEEP THE AGED CROW FOR A KEEPSAKE.
