I have a battery problem

Possible solutions:
1. Run with adapter in stead of battery only.
2. Only open 4 tabs.
3. Use another browser.
4. Replace the battery if #1 is a success.

For me, this is unlikely to be a battery problem. Why do you think so?

This sounds more like some other issue.

My favorite find is a laptop that the owner never cleaned the vents on. I can't tell you if that's it but let's get this out here.

You'll need to do a couple things in order to narrow this down:

1. Pull the battery

2. Unplug the power

3. Remove the memory, hard drive and any cards like WIFI

4. Plug the power only back in

Try to power on the unit. If the unit still shuts down after 3 seconds, it's a motherboard problem. If it doesn't shut down anymore, you'll need to add back in one of the components I mentioned above, one at a time and test power after each one; to find out which one caused the issue. Process of elimination basically.
