input100~200v(1.5a)
output19v(3.45a)
but my new charger have:
input 100~200v(1.4a)
output 19v(4.25a)
can I use new charger . will the input ampherage harm my laptop and another quest is today I was playing a game in lapto it was not just 30 min I opened laptop it siddenly shut down and after that I tried to open it but it open and after 5sec it again turned off after given a small sound and I tried and tried it opened but again after some sec it turned offed and at that time I was not charging the lapto with that new charger . what is the reason :

Off-topic.

If this is a normal good brand, it won't harm your laptop, even if the specs don't exactly match what you need.

Power units are not designed to harm anything, but, with a totally unknown device, anything can happen, of course. Input current?.. So what? This is about very basic understanding of middle school physics, basic electricity, Ohm law, etc. The current value in specs is only to show maximum nominal value the source can supply. It is not designed to be a current source, it's designed to be a voltage source; the current depends on the load, and this if valid for some acceptable range of load values (input impedance of the consumer's device). If it consumes less, it will draw less current...

If your laptop is electrically broken, no one can help you without having it in one's hands...

Would deserve 5 if it was an answer...

Thank you, Philippe. Some prefer posting answers, but this is the off-topic post...

This is not the site to ask such questions, but keep this mind:

Current (amperage) is drawn by a device. It is never pushed from a transformer to a device.

The new power supply is rated to SUPPLY 4.25amps. It's not pushing 4.25amps into the laptop.

This isn't development related, so this is really the wrong site for you to ask.

But...
Take it to a shop where they can check the charger, and the laptop.
The extra current available shouldn't harm the lappie - they have sophisticated charging circuits nowadays that limit charge according to cell temperature (and temp change rate) holding voltage, and a load of other factors.

But...it's possible that your old charger (which I assume died so you replaced it) has damaged either the battery or the lappie in it's death throws, or that the battery itself has died, which is why you thought you needed a new charger.

Only someone who can look at the hardware can tell - and we can't!
