T60- Battery doesn't recognise universal charger

[roysid]

Hi,

I bought a refurbished lenovo T60. It was fine the first few days. Battery was charging and so on.

Then the charger/adapter  went bad.

I have a universal charger and I'm using it. The problem with it is that battery refuses to charge from it. If the charger is on,

the thinkadvantage power manager tries for a second, then changes battery display to "battery not installed". The T60 would run on power but won't charge the battery.

Only when the charger is switched off/pulled out, the laptop runs on battery. I get to see battery is running but it would drain battery.

Please advise

- Is the issue with not using lenovo charger.

- Do I have to buy lenovo charger or is there any option by which the battery would get charged from "universal charger".

Thanks

non-lenovo chargers usually will charge the battery fine, but I've seen these cheap "knock-offs" get so hot that they catch on fire. I strongly suggest you get a real one. They aren't expensive. If you lived in usa I could get you one for less then $25 delivered to your door for 90watt, or $20 for 65watt. I imagine they are even cheaper in Asia, so check the costs on local websites or ebay. Good luck and make sure you verify them as genuine before you buy.

Yes the issue is with that universal charger. It's of 19 volts whereas lenovo requires 20 volts.
My wife has a T61. I tried with that. It charges fine.
