Laptop battery life...

Your battery is defective. Good idea to replace it before it catches fire.

Oooh I know I'm guessing the TP1408 on the battery charger board has popped (common) and it's the sort of thing I enjoy fixing.

When we were reviewing new laptops for the dev team, our CTO said that he wanted light laptops for when going through airports. I looked at him and asked why. I said that I've been on 3 business trips in 10 years of employment here. I don't care about airports, I want performance. In addition, many of us could use a workout. The airport argument seems to be the most American thing I've ever heard. We want bigger everything until we have to carry it.

I have a large lenovo laptop with an i9. I bought it because I needed a secondary portable desktop. I'd never use the thing for work while traveling. It's too bulky, and the battery life stinks. I'd probably gone for a Thinkpad slim of some sort. Lighter, smaller, better battery life.

Mine runs for 20 minutes off a brand new 100Wh battery, while gaming. It's an I9/4090m

... you see? There's your problem! :laugh: Surely you can use your lappy for ironing or space heating :laugh:

I've been a road warrior for many years and that argument carries a lot of weight with me. Pun accidental.

The entire laptop is 18 months old (warranty?)
Then I wouldn't describe that as "normal" after just 18 months. But then, good luck making that argument with the manufacturer. On the other hand, you're right, it might be covered by the warranty. Assuming it covers the first 18 months. I wouldn't be entirely surprised if the warranty it came with was barely 12 months.

So the CTO really meant because it would be too 'heavy'? Rather than perhaps bulky? Or some idea about weirdness with airports? If so how odd.

Lithium batteries don't last forever: and how you charge them makes a big difference. If you habitually leave them charging to "full" that can drastically shorten their life - charge to only 85% of capacity and they last a lot longer! (My phone has a optional software cutoff at 85% to do just that for me.) Have a look here: BU-808: How to Prolong Lithium-based Batteries - Battery University[^] and get a new battery!

Hmmm, interesting link, Do you remember the Amstrad PPC512 & PPC640 'laptops' I am sure I charged one in the early 80's and it's still going!

I beg to differ: the PPC range used standard alkaline C cells - not even NiCad rechargeables! :-D

I stand corrected :sigh: . C cells, probably still has charge as I remember not much used C cells! ;)

Hi All, Not really being a big laptop person, I am seeing with my work Lappy the battery is good for around 10 minutes from a full charge it drops extremely fast, I am talking 93% to 15% in the space of 10 minutes while not being used! (Outlook open, Teams open, Chrome & possibly Edge open) the thing is you need to plug it in to get any useful work done, I have got on to our IT dept about it ('Well run BatteryReport and get back to us'). Battery report shows the battery falls off a cliff. So are 'modern' laptops really bad at power management or does the OS (11 ver?) run really badly from a power point of view. Back in the day Laptops would last and last (I remember the first laptop I dealt with an Amstrad PPC512 used it on site for four day didn't need to charge it!) rant over Glenn
If something were draining the battery that fast then some things in the computer would be getting very warm very fast.

Back in the day I lugged around a Dell 17-inch XPS system whose weight was a real factor in airports. I downsized from that to an Asus 15.6-inch Core-i7 and had to buy an extended-life battery that only added to the weight. I used a wheeled laptop case to deal with all the crap you need -- it's not just the weight of the laptop, but the power block, the cables, and whatever. Now I use an LG Gram-16 12thGen Core-i7 that has amazing battery life and weighs less than a kilo. It's fast, light, has a great screen, and was a reasonable price. VStudio runs in a flash so I can realistically do on-site development when needed.

Not generally known but for more expensive items one can often make a case to the manufacturer when there is an extreme failure reasonably outside of the warranty window. After all they don't really want you going around posting that your battery failed after only 18 months.

As I read this you have a device that has the same alkaline batteries in it from 40 years ago?
I stuck a set in PPC512 many years ago, last I heard it was still working. Got replaced a couple of years ago, the company Involved couldn"t change a lightbulb.

Well it was getting warm or hot around the area of the interface. Hence me getting a little worried.

Lithium batteries really don't like being kept at 100% state of charge (it degrades them). The way most people use a laptop ensures premature battery failure. My laptop spends 99.9% of its time plugged into a docking station (constantly charging the battery). I doubt if my battery will last any longer than yours. Laptop makers should add an on-line battery mode that charges (or discharges if needed) the battery to 30% state of charge. At this level of charge a lithium battery has a greatly extended shelf life. When you need to travel, you charge the battery to 100% and off you go. They wouldn't be able to sell as many replacement batteries if they did this so I don't ever expect to see anything like this. Phil Ouellette, BSEE

Battey's in general don't like 100% or anyother value for long periods. You try to tell non-EE people (marketing!) that they look at you like you are selling snake oil.:omg:
