Haha, most users don't bring along their cooler pads one what 
And so far most of the mobile hotspots I've been to have air-con, hence eliminating the need of a cooler 

Its good to remove the battery as heat from the laptop will kill it

Practise bringing coolers out? Or practise removing batteries when on A/C? 
My old Toshiba Satellite M100's battery only lasted for 30 minutes after 2 years because I din't know it must be removed, especially during gaming 
Learnt my lesson already haha, but then the battery in my M14x is integrated one

Ya, that's the point hehe, even I don't bring my CM U2 out, I just bring a file so that I could tilt the back portion of the laptop up for better ventilation, that's all 
Tablets sure come in handy... no wonder they're selling like hot cakes now 

Then then those intergrated notbook like MBP & 15z mah die lor.. battery kenot remove...

I ought to share this with you guys. Credits to lee_what sifu for introducing the site and program, and credits to BatteryCare for the chart below

In summary:
- The battery will wear faster if you expose it to high temps (according to the chart: constant exposure to a temperature of 60C (at 100% battery) will degrade the battery down to 0 in 1 year time)

- The battery will wear faster if you leave it at 100% charge

y u can't remove? my battery is stored under 40% for few weeks liau.. after around 1 mth i will tried use it until around 10-20% then charge to 70% then leave it for few days then use until it 40% then stored it.. repeat.. 0 tear wear!
