Static electricity is locking up my laptop!

by x1800yolk / October 16, 2007 1:20 PM PDT

I have a problem. With my laptop. Sometimes, when I plug in a USB cord, Windows will freeze up and I will have to do a hard reset. I found out that it was static electricity today because when I went to plug in the cord, all I did was touch the metal from the usb cable to the metal outside the port, and it locked up. I called the company that made it, and they had me take apart the laptop and remove and reinsert the RAM, but that didn't fix it (although it seemed to help for awhile). Here is my setup:

Sager NP5760 (Clevo M570U) Laptop
Windows Vista Home Premium 64 bit
Nvidia 7900 512mb graphics card
2gb RAM
Core 2 Duo @ 2ghz

not sure what other important info I should include, so if someone would like to know anything else, feel free to ask! I would really appreciate someone's help. Thanks, Brian

Toshiba and others had such issues.

Toshiba finally issued a recall for theirs. Static is not kind to electronics so you must control your environment.

This means static treatments such as diluted Downey spray on the carpet, conductive surfaces and more. If it's truly static you may have a difficult time getting them to acknowledge it's overly sensitive.

My background in electronics design also included testing for ESD protection and that the product was not upset by discharges to exposed metal edges. While you have an issue the problem will be showing it as a bug that must be repaired as well as that name that isn't known for reacting to such reports. All I can offer is this is not something a consumer would correct on their own. An electronics designer of the right background could help but if the problem is truly bad design only so much can be done.

-> Does it do this on ALL ports or just one?

it does it on all of the ports. It's made by a small company, so I sorta sacrificed for speed in some ares, component design being one of them. Thanks, Brian

Just to be clear.

In reply to: all

If it is a discharge to the USB "shell" I (wearing my electronics design hat) would add a small wire from each shell and to where I felt the "ground" was. Modifying the machine may void the warranty but for me this is usually something I do for out of warranty work.

warranty stuff

The Sager company doesn't really care what you do with your laptop. Since they asked me to take apart the laptop, and customer service doesn't void the warranty, then I'll be ok opening it up. If I can find pictures of the inside (the manual comes with pictures of it, believe it or not) then I'll post them on my website and link to them. Thanks for the help, Brian

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
