The correct term for what has occurred is re-balling of the BGA(BALL GRID ARRAY) Chip. Hello All, interesting comments, I don’t normally reply to these things but I figured in this case I would. In the ideal world you need to get video chip off the motherboard, clean the solder, re-ball it and solder it back to the motherboard, but I wouldn’t risk it doing at home without required equipment (costs thousands). As being said before, I would not trust this fix to run for long – month if lucky. This procedure is called re-flowing of BGA soldering. Most motherboards out there are refurbished. Yep, but I really doubt that you can find a brand new motherboard for these laptops. ?Ī permanent solution is to replace the motherboard. After that just have fun with the fixed “zombie” laptop. If you are lucky and your laptop boots after this fix, back up all important files ASAP. If you are trying to recover files and don’t have an external enclosure, then this should help to back them up before your computer fries again. Ideally you have to replace the motherboard but it’s too expensive. To be hones, I wouldn’t put any money in fixing this problem. I think you are right, but for someone anxious to get personal data back or just make the laptop work for a while this could be a very easy and valuable solution. In the ideal world you need to get video chip off the motherboard, clean the solder, reball it and solder it back to the motherboard, but I wouldn’t risk it doing at home without required equipment (costs thousands).

This procedure is called reflowing of BGA soldering.
HP MINI VIDEO CONTROLLER DRIVER HOW TO
?Īlso read backing the motherboard in an oven and how to reflow failed NVIDIA graphics chip with a heat gun. Now I have to test for how long this fix last. The heatsink gets so hot that it melt solder between the chip and motherboard and the video chip gets resoldered to the motherboard. When you run a laptop wrapped in towels (bubble wrap in my case), it gets very hot because there is no air circulation inside the heatsink. Here’s my understanding of how this fix works. My fix was successful again! The laptop turned on with video and booted to the desktop. Anyway, I didn’t touch it for about 30 minutes and let it cool down. Maybe the motherboard overheated too much and shut down on its own. It was running like that for about 60-70 minutes but then I noticed that all LED lights went off. To make sure there is no cool air coming into the case through the bubble wrap, I closed all air vents with sticky tape.Īfter that I turned it on from AC adapter (again with hard drive and battery removed) and wrapped the base. It failed exactly the same way as the first one. This is a different model with very similar failure symptoms. I just couldn’t stop and tried the fix on another one.

Waited for about 30 minutes and tried turning it on. I closed it in a tablet mode (with hard drive and battery removed), plugged the AC adapter and wrapped the laptop properly in bubble wrap.Īfter that I just waited for about two hours and unplugged AC adapter from the wall. I didn’t have paper towels at work but I had plenty of bubble wrap. I didn’t really believe that this trick might work and tried it just because of curiosity but… IT WORKED!!!!įirst, I tried this fix on a failed HP tx1000 Tablet PC. Unplug the AC adapter from the wall the let it cool down (do not move it for a while).Ħ. Keeps the laptop wrapped in the towel for about one hours.ĥ. Wrap it up with towels so all air intakes are closed.Ĥ. Make sure it’s is actually on, all LEDs should work.ģ. Plug the AC adapter and turn on the laptop. This trick called “towel fix” and used to fix “no video” issue in xbox360.Ģ. I found this trick mentioned by Walliot in this post. The internal screen remains completely black and blank. The computer turns on and all LEDs light up but there is no video on the screen or external monitor. Overtime the graphics chip separates from the motherboard and the video fails. If you know more models, please mention them in comments after this post.Īs I know, the video problem somehow related to NVIDIA graphics chip located on the motherboard. Here are some HP models affected by this known video failure problem: HP Pavilion dv2000, dv6000, dv9000, tx1000 tablet PC, Compaq 700, v3000, v6000 and probably some others.
