R50e Charger overheating problems

[jonnyrharper]

Hi,

My IBM Thinkpad R50e has got some major charging problems. Basically, for some reason or another, it is causing the chargers to overheat when charging (only when turned on, otherwise they stay coolish); one even set on fire whilst being used it got so hot! I've now used and broken 4 chargers and I've swapped the battery too but this seems to have no effect.
Does anyone have any suggestions as to what may be wrong with it, or even better a solution?
Any help would be greatly appreciated (even if it's telling me it's not worth fixing)
Many Thanks

Just a thought here.But i belive your system needs the 72W (4.5A) charger.
Would you be useing the smaller 3.36A, 56W charger?
Useing that smaller charger may force it to work harder to charge your R50e.If it's working harder it may get realy hot.

Hi,
yeah I'm afraid I do have the 4.5A model. You can't buy a more powerful one than that can you? One point which may help is that it's about as powerful as it can be; for example it has 2048mb ram etc but this is supposed to be within it's limits I believe and it's how I bought it.
Thanks for your help and fast response

There is 5 different adapters mentioned at lenovo. Type in the search box "ac adapter overview" to get the details on each. The watts vary from 56, 65, 72, 90, and 120. I don't have any insight to your problem though.

I just want to add: I don't think this is a charger problem at all, I originally bought my R40 with smaller adaptor than it souhld have, but I hadn't experienced nothing like "working harder", the adaptor wasn't more hot, the problem was that with power on, the adaptor hadn't enough power to hold the system up and charge the battery at the same time, it charged only when in standby or power off. There was some strange sound coming from the R40, but nothing bad happened at all, the charging just stopped, and now, with proper adaptor, charging nor battery has no issues.

So, I hate to say it, but your problem seems to me as it's motherboard based.

Thanks for your speedy replies.
Hmm okay I might just have to resort to using it for 3 hours at a time.
Has anybody else ever experienced problems similar to this?
