2.0 out of 5 stars Dies over time, May 14, 2009

By

This review is from: Lenovo ThinkPad 90W AC Adapter - power adapter - 90 Watt ( 40Y7659 ) (Personal Computers)

I am on my third 90W AC Adapter, and this one is now showing signs of failure. It is failing in the same way that the other reviewers have said; the wires start fraying near the barrel jack that plugs into the notebook. This is how my previous two died.

On average they have lasted around 6 months before dying. I take special care to not bend that area of the cord excessively, and in general I treat my laptop and accessories with extreme care when handling them, but even with my pampered treatment of my AC Adapter, it is dying through no fault of my own.

I have called the support lines about this many times, and they will not acknowledge that this is any fault of their product.

Ideally, the cord that leads from the brick to the computer would be user-replaceable like the cord that leads from the brick to the AC wall jack is. Instead of paying $60 or so for a new AC Adapter, one could pay $10 or so for a new cord. That would definitely improve my rating of this product.

I will say that while it is in working condition, it functions as any reliable AC adapter should. But, I cannot rate it any higher than the two stars I have given it, knowing that it eventually fails to function through no misuse.

1.0 out of 5 stars Poor/cheap output cable breaks much too easily, April 23, 2009

I have had two of these fail in just about a year and a half. Both failures were due to the cable on the output side breaking between the plug and the choke. It is bad enough that Lenovo uses shoddy wire on this expensive adapter, but they also use a proprietary connector plug. It is therefore impossible to replace just the plug and you are forced to shell out for another complete power adapter. I rate this as a piece of junk. Unfortunately, there are not many other choices available. Shame on Lenovo!

P.S. I found some supposedly compatible units available on ebay at very low prices. I'll give one of them a try since it irks me to no end to give Lenovo any more money for something so poorly engineered.

UPDATE April 2010: I did purchase a third party charger via ebay for around ten dollars. The connector was the correct one and it has been working fine for a year now. It is slightly bulkier than the Lenovo, but I am highly satisfied with it and I strongly recommend that type of purchase rather than throwing away money on Lenovo's overpriced rubbish.

The Lenovo ThinkPad power adapter lasts about 2 years. (I live on my laptop) Twice I have had to replace them. This time we wraped the end that breaks with LOTS of electical tape so that it won't bend and eventually break the wires.
