I am now carrying my laptop to job and home everyday. But everytime I am back from job, it does not boot right away. At first I thought it might be because of winter, and one day it was even -27 degrees celcius. So I thought maybe for temperatyre difference. But now its -10 probably outside. Never had problem related to coldness outside and booting laptop.
Later I accidentally found that taking my laptop in the hands and moving it little bit lets him boot.
I mean when I pres power on button, I hear the fan, hear the cd-rom sounds, and HDD light is lighting for few seconds, turning of and lighting again periodically, the same with cd-rom. No text or other graphics on screen.
My laptop is about 5 years old.
Also I see near the battery icon in windows tray - when mouse over - it writes consider replacing battery. But that makes no sense for me - I use the power cable. Also I tried removing battery totaly, in case he tries to get power from battery, not directly from cable. But this does not help.
But I googled and saw posts about bad batteries. Actually the good battery is so expensive and the laptop is old, I am not big fan of buying a new battery. But at first it would be interesting to figure out where the actuall problem comes from. Ideally I could borrom a battery from someone who has asus laptop, but, I don't know such people near me who I could ask.
