Ac adapter connection is worn out, can it be fixed
The AC adapter jack on the back of this notebook (and many others) is susceptible to damage. Extra care must be observed whenever moving /
sliding or lift up and setting the notebook down while the AC adapter
plug is connected to the jack. Any force on the plug - be it left, right
up or down can cause the jack's soldered connections to break free from
the motherboard inside the case. Once this happens, the internal battery will no
longer receive a charge and when depleted, the notebook will not start up. A way to check
if this condition is present is to gently wiggle the plug while
connected to the jack. Pay attention to any AC Power indicator light
on the notebook. If it flickers, the connection is failing or failed.
This common failure is repairable, but it is not for the faint of heart. The disassembly of the notebook is required. Patience and jeweler's screw drivers (and sometimes other specialty tools and instruction guides) may be required just to open the case. Once opened, a thorough inspection of the jack's solder connections and circuit traces must be performed to identify problem points. This may require further disassembly of components. Inspect both sides of the motherboard for damage. It may be possible to simply "touch up" the broken connections with a clean, tinned 20 or 30 watt pencil soldering iron. A complete replacement of the jack is a better way to go though. The jacks are under $10 on eBay but this work is not for a DIYer that isn't willing to have the notebook reduced to the status of "paper weight". There are those on eBay that offer to perform the entire repair for about $100 when last checked, and is probably a better bet than DIY first time soldering application. Of course, the notebook manufacturer has the ultimate repair shop - but is probably ultimate in cost, too.
