Contact any camera tch for support. It is not a user repairable fault.

You have major problems. You should take it to a repair shop as it sounds like your motherboard is fried.

Probably, but it would likely require hard wiring the two together. Unless you're a seasoned electronics tech or laptop repair tech, you should probably not bother.

Place the numer to be update in one cel
In anither cel say cel=cel+1 because of the alpha "S" here you need to combine 2 things.
3 formulas in excel.
right string
add 1 to val(3charactersfromright)
combining s with converted new serialnumer
Personally I prefer Foxpro for these tasks.
For large amount of numbers this is no excel task.
Have no english excel here. Look up the easy function types.
You need no visual basic for this.

Repair Your operating system

If you have a multimeter you can test the voltage coming out the end of the AC adapter to make sure your charger is functioning properly. Otherwise as is very common with laptops your DC jack is probably "loose". Meaning the internal part on the laptop side has contacts that usually succumb to general wear and tear and have to be repaired. If you have a laptop repair facility in your area that does laptop repair you'll probably want to take it to them. Or possibly contact HP at 1-800-HP-INVENT to find out the closest repair facility for you.
