Is Laptop safe?

Been trying to persuade a family member to replace a old laptop with a desktop before it burns down the house.

the old laptop is Lenovo something. It runs slow...battery can't hold a charge for more than 30 minutes.

but said person is too cheap to replace it. And said person frequently leave it charging unattented despite my plea.

the argument goes...its been fine for 3 years so its not a risk. Millions of people do it too.

am I too paranoid and unreasonable?

My 5+ year old laptop is almost always plugged in.

If it's not your own computer, perhaps the other person would think it unreasonable to believe it's a risk.

That person would be incorrect, though.

Can't sidestep the failure to hold a charge without swapping out the old battery pack for a new one (and possibly the charge as well, as that might possibly be contributing [though, less likely to be the culprit]). Old units simply tend to lose their ability to hold a charge, over time. Particularly bad with Li-Ion, but I've experienced it as well with NiMH cells.

As for fire or explosion risk, I tend to check the heat of the battery during operation and particularly during charging. If building up an out-of-normal amount of heat, I get rid of them and swap in new. Safer, that way. If your buddy's battery isn't clearly overheating, then perhaps that risk is far less than one might think for an older battery.

Me, I'm a stickler for these sorts of things. Sort of like tires on a bike or car: swap 'em as needed, since they wear down and fail to grip the road ... and they're the only thing keeping you on the road. So, out with the old when all the signs are there. Batteries, too.

Kudos, for being a "reasonable" sort. From what I've seen of contemporary life, these days, there are so few of us.

My powerful workstation work laptop won't go 15 minutes on battery.

But frankly, if it worries you, buy a new battery. Or a better AC power supply. Or both. OMG!

On a serious note, my personal computers over the last 30 years have been desktop, laptop, desktop, desktop, desktop, laptop, laptop, and laptop. I've been laptop only since at least 2004 I think.

I've always left my laptops plugged in and have used them as desktops if I'm not using them on a job site.

Now my smart phones have gotten so hot from high processor usage and the battery trying to keep up that those smart phones have turned off with the overtemp protection. I surely hope modern laptops have overtemp protection.

I don't have time to check, but I wonder if a laptop will still run plugged in with the battery removed?

My older laptops have an easily removable battery. This one I'm typing on does not have an easily removable battery.

No, this is not a worry. It's really common for older machines.

Generally.

Having the battery is UPS (uninterruptible power supply) for a short time.

I thought the exploding battery situation was remedied by the manufacturers quite a few years ago. I've got a 5-year old laptop and it stays plugged in 95% of the time.

And gas cars never burn? Amazing, isn't it.

huge diference is, to cause diesel to ignite, it require massive pressure, oxygen, and tremendous heat. its very difficult to achieve. and its external.

on otherhand, battery doesnt require anything at all to go upin flames. battery can be sitting on a desk, unplugged, and start a fire...because all the ingredient to start a unstoppable fire is already inside the battery. all it takes is a small manufacturing defect inside, which is impossible to detect after manufacturing.

its analagous to playing with a grenade with the safety pin pulled. If you are the 0.001% unlukcy one, then it will ruin yur day or life even.
You mean like a broken fuel line squirting diesel onto a hot turbo?

never had a problem with a computer catching fire and yeah…electric cars are scary, potentially dangerous devices, well at least to the fossil fuel industry.
Personally i’ll take flammable electrolytic solvents encased in a metal plated protected battery with its arrays further divided by firewalls over gallons of extremely volatile and flammable fossil fuels….especially in front and rear-impact crashes.

Back in the day, I used to help my grandpa burn piles of driftwood using diesel fuel lit by a Zippo. We sure didn't need an 18 to 1 compression ratio to do that.

Yup, you see gas cars all the time burning at the side of the road.

Hell, my wife had an old VW that had a gas fire... she pulled over in residential neighborhood and guy rushed over with lawn hose and doused it. I repaired the extensive damage and replaced original rubber fuel lines with steel braided lines.

Gas cars burn.

Okay, this means I'm joking around. I've been pulling legs since my first post about electric cars continuing the tradition of Car-B-Qs.

Even that video is to a Youtube channel about burning vehicles. I've personally seen probably 2 dozen internal combustion engine Car-B-Qs while on the road between service calls in Texas and Louisiana. The last one was a Chevy Corvette lighting up the night sky and the one before that was a turbo diesel truck (like the one in the video) pulling a horse trailer. The horse and occupants were well clear before the fire engulfed the truck. Same with the Corvette occupants.

As long as the occupants get out safely, and the owner has insurance . . . well, enjoy the show.

I responed too quick, before I saw video. Changed my response. Sorry I snapped at you.
