Can Lenovo b550 owners clarify that it cannot run if the power cord is unplugged?

Lenovo B550 is a PC. Like a PC it sits on a desk because it is 23" monitor with no tower because it is all in one (sort of a flat smart TV screen). Needs electrical power like any TV. "The wireless" is that YOU DO NOT plugged into (hard wire)you Internet. It receives information through the air from your Home Network (such as Netgear and other brands). I can communicate with my laptops wireless from my Lenovo to them for exchanging files, pictures etc. Also it works with wireless equipment such as keyboards & a mouse through a 'transfer connector' plugged into your USB port on the Lenovo.

Unlike a laptop, which has a battery, the B550 needs power from your wall outlet to run. Unless you buy an uninterrupted power supply (UPS), it will shut down when unplugged.

Not sure, not at home to test it but I think the power cord had to be plugged in to turn it on

My guess would be yes because it has needs a power supply which it gets from it's own plug in. Also, it remains lit up when the computer is off. That being said, I have not tried what you ask.

yes, you may may want to look up a youtube video and the service manual but its pretty straight forward if you skilled with tools. Just be sure to use a delicate touch, be aware of static, and do not leave the laptop plug in or leave its battery in. Also be aware that attempting it yourself will more than likely invalidate your warranty if you have one.

Yes, I haven't unplugged it in a very long time because of the battery time issue. It get's even worse as the laptop ages. I basically use it as a desktop computer and bought a Mac as a portable computer.

Yes that's normal. I doubt if you can disable aside from disconnecting power.

Is the power cord plugged in? Is the laptop getting power? Is the power supply putting out the right voltage?

As of now, not officially supported although it will "work" but may create problems with sleep/hibernation while plugged in

The only thing I can think of is whether or not your computer is on when you try it. Other than that, I don't believe there is a power switch,(you might look it over as you may have a newer version than the two I have).

I do not know for sure about the L645. What I did was take out my battery and check if it was the same type. I've never used my computer unplugged for more than a couple hours but I've never had issues up to that point.

The power supply has a wall plug with an in line converter and a small round connector like most laptops. i would expect you can get a 240v converter that will step down the unit. I will try to remember to follow up with the exact power info Later.

Hi Susan, Yes, I had the same problem. The power pack just literally packed up. I bought the laptop Jan 2013 and by June 2013, the power cord/pack quit working. I called Toshiba and because the purchase was still within the 1year warranty period, Toshiba agreed to replace the power pack. I was asked to send the defective unit back while a replacement power pack was shipped to me - but not before I had to shell out $30 to purchase a replacement power pack while waiting for the Toshiba replacement - as I wouldn't have been able to use my laptop for the 2-3week period it took to get the replacement. All the best.

I must be plugged into your laptop and your laptop must be on to work. If you tried that then it may be a faulty one and your may have to send it back for a new one.

No need for power. I haven't tried it on any other laptops, just my Leveno.

I usually just turn it off when I'm done using my laptop, so it doesn't use unnecessary power while i'm away from it.

Mine just gave up and I purchased a new power supply on eBay with the assistance of my husband. He looked at what was written on the power supply adapter, did a search and found the one I needed. Works like a charm. It's a black cord though. I looked at the iOmega site in the first place but they have been bought by Lenovo and they don't know anything so you're on your own.

That has never happened to me, so I can't answer specifically. However, if I unplug it, it must be reset again, so I assume the same would be true of a power failure.

If you mean, can the UPS, if charged, be powered on and used to run electronics when unplugged, the answer is yes. And while I haven't exactly tried it myself, I believe that you can start a computer or other device from "cold" while unplugged as well. The only caveat as far as I know is that it not draw more wattage / VA than the unit can supply during start up.
