pregretje usb modem tušmobil sew899+

Včeri mi je neki prekinjal net in sem ga dal notri usb modem in pozabil dat ven, danes ga izvlečem ven in si opečem kazalec in plastika se zvije. Kako je možno da se usb modem tako pregreje?

Eden od razlogov pregrevanja: "If you are far from the Carrier Base station [BTS] tower and your modem getting signal less than 25% then there is a big chance to get your USB modem over heated."
