Max Rating:11V-2.8A
S/N:002J1A3773 R043D FCC ID:EJH3026E I worked on my laptop by connecting its AC Adapter(Model3026A-ADA) through wall outlet. AC Input:100-240V,1.0A,50/60Hz DC Output:11V-2.8A Laptop failed to open,does not shows Power light on its front cover.After minutes of connection to Power Socket,I touched cord from Adapter to Laptop which became hot,I feel smell of burning not sure from where exactl.I checked underside of Laptop where Power Cord connected was also warm. On Power Cord Cable(showing 10 Wires) to Laptop following is written: AWM E101344 STYLE 2464 VW-1 300V 80 Centigrade Space Shuttle Its wonder why it failed to make my laptop working as reading above shows that it can withstand 80 Celcius. Any help/suggestion pls. Will I open the adapter to check it's Protection fuse T1A/250V? In an effort to take out fuse,I have totally broken fuse glass,it was still intact with it's right/left terminals fixed in a metal cap with strong soldered legs.I have taken these remains of fuse legs to see If I can buy the same and solder it on it's previous pads. Can I run laptop without fixing fuse for Adapter? |

Can I run laptop without fixing fuse for Adapter? Sounds like the initial problem is in the laptop, not the power adapter. The adapter will not function without a correct fuse. JMK |

Before I read your post , I have broken fuse to take it out as it was
strongly soldered to legs of it's protective capping.I don't know why chinese designed it like this.For monitors/Tvs we can easily remove it and replace it.But for this adapter,it can only be removed in pieces. |

Can I run adapter and Laptop without fuse?As I don't think so fuse with
another protective capping with legs for soldering is available in Market. |

It will not function. It is difficult to solder wires to a fuse. Look for a fuse OF THE SAME RATING of the "pigtail" type. These have the wires already soldered to the end caps. Then remove the board from the adapter, unsolder the broken fuse and solder in the new fuse. |

It can be removed in one piece by unsoldering it. |
