<google>ENGELSK</google> Many motherboards are made with too cheap capacitors. After a while they start to deform or leak, and in the end the computer or power supply stops working. Capacitors in switch mode power supplies and motherboards needs to be low ESR types. These are expensive and that is why manufactures try to use cheaper models.
If you have a device witch has stopped working and the capacitors look like this picture there is a big chance that if you replace every capacitor with new LOW-ESR types it will work again.
It needs to be LOW-ESR types otherwise they will blow again soon. Farnell has some suitable types here:
- Data sheet Farnell's Robycon Miniature Aluminum Electrolytic Capacitors
- Understanding equivalent series resistance (ESR) in electrolytic capacitors
The capicitor to the right has leaked and won't work anymore
- Blown and Leaking Motherboard Capacitors - A Serious Problem - PCSTATS.com
- Legal action starts over leaky capacitors on motherboards
Update 2018
