Hello, second time I get a Toshiba L50-B with the R391 burnt, I've tried switching the KBC but I don't know the value of the resistor. Motherboard: DABLIDMB8E0 REV:E KBC: Nuvoton NPCE985LA0DX GPU: 216-0858020 The problem is the same as in this post: http://www.elektroda.pl/rtvforum/topic3089829.html - But the problem is that I cant understand the translation and also I don't have any diagram to find out what resistor I need to place there. Could someone please help? |

At Polish forum this problem was solved as follows: the KBC has been replaced and burned resistor has been replaced to zero ohm resistor. |

Ok, will try that first thing tomorrow morning. ---------- Добавлено спустя 8 минут 1 секунду: ---------- Do you think SMD 1206 4.7Ohm 250mW will do? It was the lowest I found. Was looking on scrap motherboards but could not find anything lower. |

This is kept without solution. Can't find where is the short-circuit. Have another equal computer working and found that the resistor is really 0ohm. Any ideas? I already pluged a power suply to find our where the problem is, but no success. ---------- Добавлено спустя 19 минут 7 секунд: ---------- Found out what is heating up... Its the CPU at 0.9V with 4.5A. Now what? Any recomendations? Its an i5-4200U. In the working Motherboard, there is no consumption on the R391. |
