How do I tell what power supply unit my laptop has?

Question

The power cord of my laptop is damaged (the part attached to the PSU, which you can't plug out of it), so I need to replace it. The PSU is full of writing, how do I know which of those numbers and expressions is the name of the type of PSU, i.e., the word I need to enter into the searchbox of a website that sells PC parts?

Answer 1

Nicely asked question. Good job on the pic.



Your model # is at G-8 = PA-1900-24

The key specs are at G-10 = "Output 19V ~ 4.74 A"



Any power supply with the same 19V output and 4.74 or more amps and the same connector will work. Usually I wind up searching for my laptop model + "power adapter" to find matches in Google.



Be prepared for some nasty sticker shock. Those power supplies aren't cheap.

Answer 3

known PSUs may be particularly precious. confirm it exceeds your needs. attempt and peek interior the casing devoid of commencing up it to work out in the event that they're making use of glue. If glue is recent, flow directly to 3 different maker. The glue would soften and loosen connections under load. As a regularly occurring rule, do no longer attempt to get with the help of on marginal specs on PSU of unknown makers. The greater marketed makes and fashions are often reviewed in on line web pages and regularly provide comparable consequences, i.e. they do meet the indicated specs and not plenty greater. IME maximum PSU will function ok as long as they are actually not abused with the help of going previous the gadget limits, i.e. do no longer over clock. Your 700W unit would desire to be nice, do exactly no longer forget that the guarantee will probable in uncomplicated terms conceal alternative of it and not something of your gadget would desire to it blow up. good luck. N.B. I even have not used one with the help of this maker.
