My netbook power cord is no longer working. the netbook charges fine on my labtop cord. will this cause any problems to the netbook?

Is the AC cord the original? Has it been damaged? Have you tried another AC cord, with the EXACT same power specs? It may be a damaged AC jack. Sometimes a pull or tug on the cord while plugged in will loosen the connection. If you wiggle the cord at the jack plug does it cause the charge LED to blink? Does the computer work on battery?

I recommend that you dispose of the power cord and replace with a new cord as they are no longer able to be repaired due to sealed plugs. They are fairly cheap too these days costing between $5 and $10. This is a much safer thing to do than to try and repair your cord as it may be fixed very well but if repaired it will increase the risk of damage or fire by 110% as they are designed to work at certain limits and if the repair causes it to fall below or exceed it then this is where major problems can arise. I hope this helps.

how old is the battery it might be past the use by date
when they get to old they usually take longer to charge

hope this helps

I would think the battery is defective.

remove the battery and check if your laptop can boot or turn on for the matter, if so then the problem is the battery if not then the problem is either the laptop power protector is busted or perhaps the port or the adapter itself is bad.. to check the adapter use a tester to see if there is any power coming out if so then the problem is either the port or the motherboard itself.

Before you panic see if there is some hidden reset code from the manufacturer. If not, then you get concerned.
Check to see if you are using the right protocol to get it out of the hibernate mode.

It sounds like a power cord issue could be the problem, as you have confirmed that the power cord is not working using a volt meter. However, it is also possible that the power supply in the MSI u100 netbook has failed, which would prevent it from turning on even with a working power cord. Additionally, the fact that the Seagate hard drive also failed and was warm to the touch suggests that there may have been a power surge or other electrical issue that caused both devices to fail. It would be best to take your netbook to a professional repair shop to diagnose and repair the problem.

This problem is usually caused by either a worn out battery (if you've had it for quite a while) or a faulty adapter/power cord. If you know anyone who has a similar Acer Aspire One Netbook, you could try using their battery and/or power cord to narrow down the issue. You can also buy laptop/netbook batteries relatively cheap on eBay and even if the batter ends up not being the issue, you will have a spare battery to take with you or for down the road when your current battery wears out.

do you still have your battery working? if not, you may have a problem with the adapter. could be a partial contact from the main adapter or at the charging port on your laptop. use a tester and check for continuity on the adapter cable and also check the power output going into the laptop.

When you install a new battery and remove a battery always make sure the laptop is completely shut off and have the power cord removed so that you avoid any possible power surge.

Batteries generally don't last much longer than a year and I have found removing the power cord or battery when it is off to be a good practice.

Before you charge a battery make sure it is run most all the way down. Recharging a battery when it is not run down can give it a memory and you may only be able to charge it up to the point you started charging it.

Anyway, if the computer won't charge a new battery then you could have a bad motherboard. To be sure try another battery.
