Tablet pc i have a nec versa litepad tablet pc but it will not show any signs of power so i took it to the repair shop and he replaced the d/c jack and it still wont show any signs of power please help

may need a new battery go to your local repair shop or if the tablet still in warranty ring the manufactory

remove the battery, connect the ac adapter and turn on the laptop. If it turns on then it's your battery. If it doesn't turn on then it is either your ac adapter, your dc jack, or your system board.

If it doesn't turn on then try a different ac adapter from your local pc shop or electronics store. If it still doesn't work then try moving the ac adapter connector and see if it attempts to turn on. If it does then it's your dc jack. If it is your dc jack then you will have to replace it. The problem with that is that it can be pretty expensive to replace it.

The way I have solved this is by ordering a dc jack on ebay or any other online parts supplier and replacing it myself. If you can take your computer apart and put it back together then it's just a matter of desoldering and soldering the new one. If you want you can have a pc or tv shop do the soldering for you.

Have fun and let me know if you have anymore questions.

Call the Fujitsu service 800 number, you may still be under warranty.
It sounds like the inverter has burnt out, take it to a Fujitsu authorized repair shop, your tablet has a security feature that will lock you out if it is opened by an unauthorized repair shop or anyone else for that matter.
They take your tablet security very serious.

The motherboard needs to be removed from the laptop in order to repair properly.

Almost all NEC litepad's have that problem, it's caused by AC current leaking fromt he adapter. Seacrch for LitePad Fix on google for a software solution. Also, preferably change your AC adapter to a OEM.

I do jack replacements. It requieres soldering and completely dissasembling the laptop. Do not attempt unless you know what you are doing and have the proper tools and work setup. If you still want to do it yourself (at your own risk of course) you basicaly need to take the laptop apart, remove the brokem jack (de-solder) and put in the new one. Use maximum of 15Watt soldering iron. You can get all the tools you need at a local radio shack or electronics store. Good Luck.

I do not know if this will help your situation any or not. I just posted this in a seperate threadI purchased a used TC1000 for $35 (I just couldn't help myself, despite what the owner state was happening).

It would power on, but no Compaq POST.

Toshiba taught me a simple trick when I was having issues with my X205 gaming laptop. Basically, remove all power sources (including battery). Hold the power slider to the on position for 25 - 30 seconds. Then power back up. You have to discharge whatever electricity is in the board/ps otherwise I believe the MoBo senses additional charge/not enough charge and refuses to boot.

I did this and have had 25 successful boots in a row.

Please take the laptop to a repair shop for analysis. Possibly faulty motherboard or other parts. Repair price may be high.
