Back from work yesterday, I found a laptop in a trash (Maxdata Pentium IV, 45Gb HDD, DVD R/RW, 15" display). The RAM was missing, but this laptop uses standard DDR memory. The laptop also comes with a power adapter (20V DC / 6A)
The battery was charged enough to boot the laptop up, but I'm not able to charge it again. When I plug the power cord in the laptop, the LED on the power adapter starts the blink and I can hear a small buzz. The buzz comes also from the computer and it smells like hot electronic components (so I removed the power cord). I tried this with and without the battery : same result !
I can't say if the power adapter is dead or if the power input unit of the computer needs to be repaired.
Here are some questions :
- Can I easily change the power input unit of a laptop ? I don't think so but ...
- Do some generic battery charger units exist and do you know where to find them ?
- Do you know how to bypass the power input unit of a laptop to charge the battery inside the computer ?
Please excuse my English, my mother language is French.
