Small things done well~

    There is a feature of Intel Core i series CPU--high frequency noise due to the energy-saving design. I don't know why they don't care about this high frequency noise when designed the system, but still some models seem to have no such problem. I guess maybe the manufactories need to use some more expensive soundproof components. Anyway, Sony obviously didn't notice this situation and let the noise problem become the main defect of all the core i CPU series. 
    Fortunately, Sony unlocks the BIOS setting of CPU support C3 C6 function. Now we can disable this energy-saving function to temporary make the noise disappear. But I think they still need to figure out some way to really solve the noise problem with c3 c6 function activation. 
    Due to the weak battery life, I bought a new BPS22 battery for my EA37. There is some tests for these 2 battery with c3 c6 activation or not. 
    First, the battery spec. is below:

 

1. BPS22A: original supplied accessory of EA series--10.8V 5000mAh 6 cell


2. BPS22: original supplied accessory of EB series--11V 3500mAh 4 cell

    Recently, I bought a new laptop for replacing the old one. If you observe the laptop market, something you should find--cost down. In the past, PCMCIA or express card slot is common in almost every laptop. However, now, there is only few laptops have this slot. Perhaps for some users, they don't need to extend their laptops, but still some users need to use this function. For me, through express card slot, I can extend to have a usb 3.0 or DVB-T.
    Therefore, I'm looking for a laptop with express card, e-sata port, 13 or 14 inch LCD, less than 2kg, higher resolution than 1366x768. It's hard to find one can all meet my criteria if my budget is 40k NTD. Finally, after some compromise of mobility, I chose Sony Vaio EA37 for my new laptop. 
    Let's see its main specification:
