65w adapter and 90w laptop power adapter What is the difference?
In general, notebooks have to use power consumption is to decide whether to use 65W or 90W adapter power supply, but not to say that 90W must not use the 65W power supply, but his power is not reached, it is possible that the machine is using some of the features Can not start, for example, external equipment, power supply, if the original request is 90W power supply, but you are using the 65W power supply, external equipment can not work properly. But some cases do not need external equipment, so choose a small 65W power supply is very convenient
According to ibm specification
T6 x6 r6 series power supply is compatible
The difference is x6 this thin model with 65
The official explanation is (original English), in the 90w models using 65w machine may be in high power consumption, can not meet the system requirements. That is, while the side of the charge side of the use, it is possible that the computer can not run at full speed.
In fact, the use of and there is no problem, but also little, at least the machine is no harm.
For psychological factors, you can buy a 90w, Taobao fake a lot, you are not professional or to Jingdong to buy, about 250 yuan, although it is more expensive, really is the original.
65W and 90W is mainly based on your laptop power configuration, the general integrated graphics with 65W, discrete graphics because of the need for additional power supply, so the general need 90W, of course, there are some low-power CPU, such as 25WCPU , 35W, 45W difference, these are the beginning of the manufacturer according to the notebook's power consumption count a maximum power, and then give your laptop with adapter
90W adapter can replace 65W, as long as the interface is the same, but 65W instead of 90W sometimes there may be insufficient power lead to automatic shutdown.
In general, the greater the number of watts, the larger the head, because the adapter is actually a coil will be 220V into 19V, according to the power to determine the head, the larger the watt, the same 19V, then the output current will be greater
