I have damaged my power supply from the short one and can hardly switch on my laptop.
I tried with a different power supply, from another laptop, to get the laptop, or to be able to charge the battery at all, but it doesn't work.
When I plug in the power, the power button lights up for 3 seconds and when I press the power button, the charging signal flashes that should be charged.
Do you have a suggestion? What should I do? Alternative to be able to charge the battery? How do I charge the battery? Do you know which one I need for the power supply? Where can I order it for cheap?
Can you do it differently?
The power supply shows how many volts it delivers, and the laptop shows how many volts it needs. You can use any power supply where these two values match.
Never use a power supply that supplies more voltage than your laptop needs. This can (if the difference is too high: will!) Damage or destroy it!
Thank you very much. The laptop says: 19.5 Vdc, 10.3A and 200W. Does it mean I need exactly 200W with 19.5Vdc and 10.3A and what is Vdc anyway?
You only need another laptop power supply with the same voltage and approximately the same current.
The voltage V (volts) should be the same. So laptop 19.5V required, the power supply can tolerate 19.5V or 19V.
The current A (ampere) is the maximum current the power supply can deliver / the laptop will use to the maximum. The amps / A should also be approximately the same, but can also be higher. The laptop only takes what it needs.
Voltage - V should be the same
Current - A should be at least the same as the old one
Vdc stands for Vold Direct Current. So your laptop needs 19.5V DC.
Ampere (A) and watt (W) don't matter (more or less). The following applies: Watt = Volt * Ampere
If your power supply has too much amps, that's not too tragic. Your laptop will simply take as much from the oversupply as it needs. It can only happen that your power supply works inefficiently, i.e. Uses more power than necessary. So in the long run I would get a suitable power supply.
If your power supply is low on amps, it means your laptop won't charge as fast as it could. In operation, it may discharge faster than it charges. You should then charge it when it is switched off before you can use it.
If your power supply is low on volts, it probably won't work. Your laptop won't or won't fully charge.
! If your power supply has too much volts, your laptop will break!
As already mentioned, watts result from volts and amps, so you can just ignore it.
So you have to look for a power supply that delivers 19.5V dc. Lines are also painted on many power supplies, google times "dc symbol", then you see what I mean. 19V will probably be ok too, I would give it a try. 20 is probably still acceptable. But that's a bit of a risk. I read that it becomes critical from 10%, that would be about 22V. I wouldn't do it.
Btw: If you use a power supply with too little ampere, the power supply can break due to overheating. So not really optimal.
Vdc, stupidly written V DC = Volt direct current.
I wrote that too?!
