Presario V3000

This is an extensive fix, You will need to tear the laptop all the way down and remove the motherboard in order to remove the old jack and resoldier a new one. I purchase all jacks for my shop from Ebay, you can generally get any jack for $3 to $6. Here's a disassembly guide for an r3000, it's similar to the v3000, and from experience, I can tell you that all laptops are similar enough that once you take one apart, you can take just about all apart. You might browse the site at the lower link a bit, it has many different assembly files, you may find more that will help.
