Full thickness thigh burn caused by a laptop computer: It's hotter than you think

Thermal burns on lower limb resulting from laptop use: A case report and review of literature

“…[ 5 ] In another, the patient was an insulin dependent diabetic without definite neuropathy, but was also under the influence of alcohol at the time the burn was sustained. [ 3 ] This, together with our case report, reinforces the need for “at-risk users” with impaired sensation, to be educated about the use of protective equipment with prolonged laptop use.…”

“…As in the above case, they are most commonly associated with thigh burns. [ 1 2 3 4 5 ] However, there is a case report of a laptop-induced burn causing irritation and oedema of the penile prepuce with associated blistering of the scrotum. [ 6 ] More recently, there has been a case in which the use of a notebook computer, led to severe second and third degree burns of the foot, which eventually necessitated forefoot amputation.…”

Laptop computer induced erythema ab igne: a new presentation of an old disease

“… 6 , 7 The capacity of laptops to generate heat depends on the model and central processing unit (CPU) components in the laptop. 8 Most of the heat, which can vary from 80°C to 130°C, is generated by the central CPU, graphic processing unit (GPU), lithium battery, and CD/DVD inner motor. 8 The high temperature, which is dissipated by a fan system, may produce skin changes like EAI.…”

Total suspension of exposure to heat is the immediate and most important treatment.…”

Laptop Heat and Models of User Thermal Discomfort

“…Paulius et al (2008) surveyed 11 laptops on a solid surface with optimal ventilation and measured the bottom surface temperature with an infrared thermometer and found the base temperature ranged from 35.0°C to 43.2°C under normal use. Similarly, Tsang, et al (2011) measured 10 laptops and found that the highest base temperature was 55.4°C. To test the effect of suboptimal ventilation Paprottka et al (2011) studied laptops placed on a soft surface, and found that the temperature at a vent reached 65°C, far beyond the skin burn threshold.…”
