1175528	2011-02-06 03:05:00	Hi PressF1 Today I dropped my power adapter and it started to spark when I plugged it in, so I think its time for a new one. However the defualt 90w power adapter that I got with the laptop (and is now broken) seemed to get very hot and would sometimes cut out, I assume due to theramal limit. I noticed that dell has had some trouble with shipping some of their laptops with power adapters that are too weak and was wondering if I could get a 130w power supply. This is mainly where I get into trouble, as I am not really sure if this could damage my system. The power supply that I have now (90W) is rated as: AC Input: 100 ~ 240V 50~60Hz DC Output: 19.5V 4.62A 90W The 130W adapter is: AC Input: 100 ~ 240V 50~60Hz DC Output: 19.5V 6.7A 130W Thanks	Fifthdawn (9467)

Voltage is the principal criteria, so the higher rated supply will just run cooler, that's all, and be all the more reliable for it! Cheers Billy 8-{)	Billy T (70)
1175531	2011-02-06 09:00:00	After the voltage and the minimum wattage the next critical property is the plug that fits to the laptop . There are about 50 million different plugs on these things and they tend to be model specific so a generic or 3rd party adapter may not fit physically into the socket on the laptop . (50 million is probably a slight exageration) but it seems like that when trying to find one that fits . Sometimes the only answer is to cut and paste the output lead and then you have to be careful about polarity, it is DC and if you get it wrong, that's when you could wipe out your computer . My advice would be stick to the manufacturers replacement part, your risking a $500-600 laptop main board for the sake of a $50-60 power adapter	jinja_thom (4306)
1175532	2011-02-07 01:53:00	So basically that power of the adapter doesn't matter, so long as the connector on the adapter is compatible with my laptop I should be ok?	Fifthdawn (9467)
1175533	2011-02-07 02:11:00	So basically that power of the adapter doesn't matter, so long as the connector on the adapter is compatible with my laptop I should be ok? The voltage must also be correct.	inphinity (7274)
1175534	2011-02-07 02:15:00	Yeah Voltage + Adapter is what matters most. The universal ones you can get from DSE for $70 sometime are pretty good, they let you set the voltage and have a myriad of interchangeable adapters. Wattage will just make the battery charge faster AFAIK.	Chilling_Silence (9)
1175535	2011-02-07 03:27:00	Dells are fussy and will give you a POST warning (and from memory won't charge the battery) if you use some adaptors, I would go genuine or oem replacement over a universal.	Alex B (15479)
