Still, the matte display on the T430 delivered sharp, crisp text on CNN.com and. Fortunately, that screen is also available on the T430, a $50 option we highly recommend. This is somewhat disappointing, given that the previous model, the T420, had a much brighter 230-lux screen, and a higher resolution of 1600 x 900.

We have a guy from Greece on this forum who has been buying from some shops locally in Greece (over the internet still) and he says those shops offer a 1 year warranty on no-name 3rd party batts, so he was reasonably happy with them. What I will most definitely advise against is buying a no-name 3rd party, some £10 on ebay - I would have too little confidence that such battery has got enough of safety features implemented and the cells could well be reused cells. But then an old original batt I have did tank as well on a couple of occasions I haven't yet seen anything bad written about GreenCell - and they seem to have been on this market for longer than KingSener. I was super-happy about KingSener and advising everybody to buy it until it started tanking at 30%. On the other hand 3rd party batts seem like a gamble too. Again not sure how many sellers will answer. You can ask what the remaining capacity is as reported by battery itself. So there is an element of a gamble in buying an original. There must be some way in Windows, but I have never yet seen a seller on ebay that would be telling this info. For me the way to find out is to attach to a machine with Linux and TLP and run "sudo tlp-stat -b". The original batteries did come from different manufacturers, I understand some are regarded higher than others but the sellers typically don't know which one it is. My own T520 9-cell batts are in a decent shape for their 8+ years of age - but then I normally run my machines plugged. Some people are super-happy about their long-lasting original batteries. Good question to ask Unfortunately I don't know the answer.
The original batteries on my T520-s are still okay-ish, so maybe you can be lucky and find a good original possibly on ebay.Įdit: Is it better to buy an original (probably used) or just a 3rd party brand like greencell? My KingSener from AliExpress for X230 hasn't been horrible - I will keep using it - though it did start to tank down after 30% - much to my upset. I guess connecting them initially via a power resistor would be a wise idea.Īll in all probably makes sense to splash out on a proper replacement. I don't think I'll be able to close it back neatly Also care needs to be taken never to connect together cells that are charged to significantly different voltages - or else you will get a rapid strong flow of current from one into the other - which is a fire hazard. I've opened one battery so far myself, a T61 one. cell in parallel to a pair of cells you plan to remove, so called "bridge" cell, then you remove the original cells, then you add new ones and then remove the "bridge" - the trick is that the controller never sees 0v on that pair of cells. The way not to upset the controller is: first you connect a temp. So you need to take care not to "upset" the controller (or else find a way to reset it which is its own kettle of fish). And if the controller gets upset it just sets a flag in its EEPROM and switches off the MOSFET-s - the battery becomes dead.

Secondly the battery has got a full blown microcontroller - it's a computer of its own. For one thing there is no space to do soldering - you can only do spot welding. Reportedly replacing the cells requires some care and effort.
