Samsung Laptop - Sometimes alive, sometimes dead.

Hi, I have a Samsung NP-E352 laptop.

Recently, the battery warning came up to suggest my battery needs replacing. But a couple of days later, it completely died altogether. No power, no lights nothing. I tried taking the battery out and just using the mains power, but still nothing.

I checked how much life was in the battery by pushing the button on the bottom of it, it said 20% charged. I don't know if the laptop should still work with the mains plugged in and the battery removed, my sister's laptop does, so I'm guessing mine should?

Anyway, I assumed then that the motherboard must have a problem. However, today I plugged it in and switched it on and it booted up and worked! Well, it worked for 20 minutes, then died again. Now the battery light does nothing when I push the test button on the bottom of it, so clearly the battery is now useless, but can the battery be the only problem here??
 
The laptop should work normally with it plugged into power without the battery. Do you have it plugged in all the time? If so, you shouldn't be doing that as it will cause damage eventually. Does the charging light come on when you plug it with the battery attached?
 
Hi, thanks for the reply.

Yes, I usually have the battery in and the power plugged in all day.

I just put the battery in and plugged in the charger. The charging light isn't coming on. Everything is totally dead. I took the battery out and tried booting up with just the mains power plugged in, but again, nothing.
 
As I said before having it plugged in 24/7 is a bad idea. You should take it in to have it diagnosed what is wrong with it before you go spending money on a new battery and the charging system is shot on it.

However, sometimes the charging port inside the laptop gets damaged and it won't charge or the connector/wires on the charger get damaged and won't charge.
 
Ok thanks. I usually had it plugged in maybe 10 hours a day, so I guess there's a lesson learned.

One of the things I used to use this laptop for was to play my backing music at gigs (I play guitar in pubs). I noticed that recently there was a lot of interference noise despite me having a professional external sound card and discovered that it disappeared when I removed the mains power, so I guess that leans towards what you say about the charger or the input.

Many thanks for your advice :)
 
Just an update. I bought a used laptop, slightly newer, higher spec of the same series. The battery & charger are the same. I was just going to throw my old hard drive into it & carry on, but first, I thought I would try putting the battery in my old laptop.

It turns out that both the battery AND the charger from my old laptop were broken. The old laptop is working 100% perfectly with the new battery & charger.

Thanks once again for your advice, much appreciated. :)
