As My old netbook becomes more and more addictied to its power adapter and finally can't live without it anymore, i thought it would be time to replace it. But shocking: this rare model in this pretty white color cost's more than 60€. And as a follower of the self repair manifesto and knowing that the produces uses also only standard parts i decided to replace the cells. This costs about 10 bucks, an hour of work, minutes on ebay and a few days waiting for shipping.
The last working state of the pack is long ago, so the OS has no idea of whats happening in there.
After the replacing it seems i could work about half time longer than with the fresh original part.
Step 1: Preparation
Step 2: Open the Case
Step 3: Changing the Cells
The Direction of the cells should be concluded from context (cable color, prints on the cell or pcb).
Just in case if someone asks: the cells are mounted this way:
red> (+ -] (+ -] (+ -] <black
and between the cells goes some wire to the circuit board for monitoring and protection.
In modern computers you should find normally li-ion cells. It should be printed on the label. The supply voltage should be a multiple of 3.7Vdc, so you also have a hint of how many cells you find inside.
Disclaimer: If something went wrong, it was your fault!
WARNING: loaded and shortet li-ion cells tend to explode from time to time. Also not my fault, even not my Idea.
Finally, my device is offline (off-cord), wardriving through the neigborhood, annoying apple-fanboys as wifi-jammer again, it runs hours and hours around with no cable and even can left the icu with no doctor around!
All in all a good solution on nearly any cell driven devices, also drills, flashlights etc. where no spareparts are available anymore. And much more cheaper than original spare parts!
