Last year I bought 2 laptops, 1 for me and the other for my daughter. They are Compaq Presario's. My daughters charging wire was intermittently not working unless you moved it completely sideways and i always thought it was the connection inside the computer cause thats what happen to my first laptop before we bought these 2. Mine started doing it 2 weeks ago and then stopped charging all together. Since it wasnt working I decided to test yo see if it was the wire or the computer and found and old wire with the same size end and cut both ends off and switched wire ends and VIOLA! A new wire from them or a computer store of its equivalent is between $55 and $90. I went to Walmart and found a cheap caller ID unit for $7.99 and fixed the other wire with electrical tape and some heat shrinks that Ive had laying around for 3 years. Youd think that for $700 each they would give you a decent wire as it will most likely be put in and taken out often.
