Asus Eeeeeeeeeeeeeee 1005HA
So, I have this Asus Eee PC1005HA that's not powering on, not getting anything from the charger being plugged in all of that good stuff! I cracked the little guy open and pulled out the board and found a crusty little ____________ right near the DC input. I cleaned up where the ______________ once was and I have posted a picture below.
Can you help me fill in the blank? Or does anyone have the schematics for this board? Thanks guys!!!!! |

Re: Asus Eeeeeeeeeeeeeee 1005HA
Ah, let me add that board model is 1005HA Rev. 1.3.
I have not been able to find schematics for 1.3, however I was able to come across the 1.1. I don't know how similar the model would be and if there is any difference in the way they set up the incoming power. |

Re: Asus Eeeeeeeeeeeeeee 1005HA
I was thinking it was a fuse, but how would I even go about trying to find out the specs on it? I just took it off, there was nothing but blown remains, This thing really popped! I wish I could find some schematics for this, unfortunately all I was able to find it for was the rev. 1.1. Well, I will continue my search in the morning. Thanks for your post though!
Thank you, Pete |

Re: Asus Eeeeeeeeeeeeeee 1005HA
one way you can tell, albeit may not be a good idea (see: last resort). Is to jump the connection with a blob of solder. If it works, its probably a fuse. If it catches fire/explodes or in any way destroys the power adapter or board components, suffice it to say its not

Re: Asus Eeeeeeeeeeeeeee 1005HA
True! I think I'm going to hold off on that for now... lol! I'm going to see what I can find on this and go from there. I think I'm going to email Asus as well to see if they would be willing to supply any information. Even if I can narrow it down to a fuse, I have no clue what fuse to put in it's place.

Re: Asus Eeeeeeeeeeeeeee 1005HA
So, as I'm sitting here looking around for additional information regarding this board, it hit me! I think I have a similar Asus Eee PC1005HA in my computer graveyard. So, I go take a look and to my surprise, I do have one! I crack the thing open and it's my lucky day! The motherboard is Rev. 1.3! Well, here is a shot of what is intended to be in the place where the blow out was!

Re: Asus Eeeeeeeeeeeeeee 1005HA
Seems to be a common fault with Eeeeee PCs:
http://zaverio.com/~asbesto/lab/701/ Looks like a small 1A SMD SOD323 diode. What is the input current rating of the laptop?

Re: Asus Eeeeeeeeeeeeeee 1005HA
Here is the DC power schematic for the Asus Eee 1005HA. This is REV. 1.1 but the diode is the same for REV. 1.3.
Now, I will stop overloading my own thread with comments... lol! |

Re: Asus Eeeeeeeeeeeeeee 1005HA
No, I have to order the parts. I didn't want to take it off the other board, because all that needs is a little reflow or reball. I have a couple of monitors to open that will most likely need some caps so once I get a parts list together big enough to make it worth the shipping charge I will place the order and give it a shot.
I will be sure to update the thread with the results though. |

Re: Asus Eeeeeeeeeeeeeee 1005HA
Hello Peter9DO,
I have the same problem with my Asus EEE PC 1005HA. I inverted the polarity and now it can't recharge battery, even if, using a full battery, he works very well. I opened it and I saw that I have the same burnt chip. Have you repaired your pc? Does it work now? Thanks in advance, Max |
