Resolved Question

Just curious about 2 things:

Aug 15, 2014 6:19AM PDT

1. What does removing the battery and putting it back in do on a laptop that powered on but had a black screen before I did that. After I removed the battery and put it back in, it booted right up. Just would like to know why?

2. Should you leave the Power Cord connected to a laptop after it has been shut down?

I would appreciate it if anyone could answer these questions for me. Thanks,

MIKEY

1. Not a good idea.

In fact any maker should void the warranty for that alone. It's NOT safe, you took the risk and now want to know why it worked? Count your blessings it did and didn't just burn out.

2. YOUR CHOICE. A good machine can handle it either way.

What's wrong ...
Aug 15, 2014 6:29AM PDT

with removing the battery when the laptop is turned off (that's how I read this post). Did you interpret it otherwise?

That's the way I read it.

I've seen folk do that and I cringe each time.

Hi Kees,

Yes, I did remove it when the power was OFF?? Perhaps Mr. Proffitt misunderstood my question, or, I mis-phrased it. Thank you, Kees, for your kindness in taking the time to reply.

Thanks for the info, Mr. Proffitt. I didn't know that removing a battery could void the warranty. Thanks again for your kind response.

Removing a battery when the power is on
Aug 15, 2014 6:37AM PDT

Is just a bad idea. However there is a little known reset where we power down, remove the charger and then the battery along with a button push that has brought back many laptops. That is some reset that some laptops have and is not well documented. However good techs all over know about that.

I'm sorry, perhaps I just mis-phrased my question. The power had been turned OFF on the computer, as wellas, I had removed the power cord from the computer before removing the battery, BEFORE I removed the battery.
Thanks again for following up on my question. You are always so kind to help whenever I have a problem or question. CNet is the Only forum I use and your input always seems to be helpful.

Good to read that it was not what I thought it was.

There are circuits that are powered via mains or battery that turn on the entire PC or laptop. These are hopefully robust but once in a while you encounter a wonky unit. You try the usual reset (which is noted in the CNET Laptop Troubleshooting welcome post) and hope the issue is cleared up.

However if this laptop is off and powers up when you slip in the battery it sounds like the old BIOS setting of "Resume on Power." There are thousands of PCs out there and many share BIOS from a few sources so this feature is in many PCs. Here's a link on that but it does not mean this laptop has that feature but given how hard it is to find custom BIOS coders today and all the patent issues, my bet is on this feature. It may not show in any menu but I'd take bet the code is in there.
