How much would it cost to have my laptop battery fixed


How much would it cost to have my laptopLaptop Battery Lenovo ThinkPad L520 fixed
Well I got a refurbished Toshiba L850 for Christmas and it's really great. I know that batteries wear out after a while if you keep them plugged in constantly so I made sure to unplug it when I went out and when I went to bed.
But the problem is the Laptop Battery Lenovo G460 has stopped working now. It wont charge and every time I unplug it it dies. I did a trick where you try to turn it on without the battery in to make sure it is not just the cable and it still worked without the battery.
I am wondering if a connection has broken or something along those lines so want a proper technician to look at it. But just wondering how much it might cost in somewhere like PC World or similar.
Just to start with, unplugging the power adapter does not improve battery lifespan. When the battery is fully charged, charging ends and, from the battery's point of view, it is pretty much the same situation as if there was no Laptop Battery Lenovo ThinkPad Edge E320 power adapter attached. Modern laptops have very intelligent battery charging circuitry that takes good care of the battery.
Similarly, removing the battery while you are NOT using the laptop does not improve battery lifespan. However, removing the battery while you ARE using the laptop does improve battery lifespan. This is because the heat from the running laptop reduces the lifespan of the battery.
Personally, I stick to this rule: if I am using the laptop, and it is plugged in, and the battery is fully charged, I remove the battery from the laptop. (The only downside is, if there is a power cut, the HP Compaq 6735s battery isn't there for backup, but that's only happened to me once!)
There are two possibilities I can think of for why the battery won't charge.
1. The battery has reached the end of its useful life and needs replacing. Seeing as it's only four months since Christmas, that seems highly unlikely.
2. There is a bad connection between the laptop and the power adapter, and the laptop is deliberately refusing to charge because it cannot identify the power adapter.
Laptops tend to have a "feature" whereby the laptop can identify what model of power adapter you have connected. Supposedly the idea is that if you connect a power adapter that is too low-powered, the laptop will refuse to run at full power, to avoid blowing up the Laptop Battery APPLE A1280 power adapter. Similarly, if you connect a power adapter that the laptop cannot identify, the laptop will say "hang on a minute, I don't know what amount of power this power adapter is able to supply; I'd better not do anything too power-hungry, just in case I blow it up". Usually, running at reduced power means the laptop will not charge the battery at the same time as it is switched on, and may run the processor at reduced speed.
The problem is, if the connection between the power adapter and the laptop becomes bad, the signal that tells the laptop what type of power adapter is connected might not get through. The laptop will then go into the low-power mode, because it doesn't know you've connected the correct HP Compaq NC6100 battery power adapter.
The repair is usually to replace the power jack where the power goes into the laptop. This is normally the weak point. The actual plug that goes into it tends to be more robust. This repair should be done by a skilled technician who knows how to avoid causing heat damage to the circuit board while soldering, and who knows how to avoid causing electrostatic discharge (ESD) damage to other components.
A repair will probably cost between half an hour and one hour of labour (though there's probably a minimum charge of 1 hour) and a couple of pounds for the replacement jack. You are unlikely to get "while you wait" service. Expect drop-off-and-return service.
However, because your laptop is quite new, it is probably still under warranty, so you can probably get it repaired for free under warranty. This will probably involve sending it off by courier to be repaired and then returned by courier.
A temporary work-around is to try charging the Dell Inspiron 1525 Battery while the laptop is switched off. The laptop may "permit" this, because, with everything else switched off, the total power usage may be low enough for an under-powered charger to handle.
DO NOT BE TEMPTED to wiggle the power connector around, or apply pressure or force to it. This sometimes makes the connection work better on a temporary basis, but it is the start of a downward spiral. The more you do it, the more you have to do it. Eventually, this causes damage where the power connector attaches to the circuit board inside the laptop, and this can make it much more difficult to repair. If you get to the point where the laptop will only work if you wiggle the connector around, get it repaired before it is too late.

the HP g60 battery which you have now has reached the end of it's re-chargeable life cycle and needs to be re-placed with a new battery, this is normal for re-chargeable battery's.
there's no need for a technician just because the battery has stopped working, simply remove the battery from the laptop and re-place it with a new battery of the same make/type.
You need a new Dell Latitudo E4200 battery and try again
