Rut-ro reggie!

It's H.A.A.R.P. or aliens from space!........

Or maybe it's a bad Bluetooth/Wireless Module; in the laptop, lol!

Radio Frequency Interference or Electro Magnetic Interference, I can see from an outside source..........but Blue screen too?

Leads me to believe a bad hardware component.........

Go to Page 35. (Adobe Reader page number at Top. Actual manual page is 27)

Let's use the Athens 9485GN for an example.
HP part number - HP 655795-001,

See the gold plated contact pins on the bottom?
FOLLOWING Anti-Static Procedures, a pencil eraser is used to clean those contact pins. BOTH sides.

If using an eraser on the end of a pencil, and not a solid eraser; refrain from letting the metal band on the pencil, touch the gold plated contact pins.

Rub up and down, and back and forth; on all contact pins.
Doesn't take much pressure, nor rubbing, to make a clean contact surface.
(Doesn't take much 'corrosion', to make a bad contact surface)

Use air to remove the eraser dust. You can use a can of compressed air for computers, if available; or air pressure from your mouth will be sufficient.

Also clean the copper area (Holes) where the mounting screw/s go through.

Also clean the Terminals. Main and AL I

Try to clean the connectors on the wires that go to the Wireless/Bluetooth Adapter card, also.

(Wireless Antenna wires)

Reinstall Wireless/Bluetooth Module. Reconnect Wireless Antenna wires. (Properly)

If this does not resolve the issue, then suggest replace Wireless/Bluetooth Module.

Agree that I am 'going out on a limb' with these statements.

Could be something else. May be damage to the LCD Cable. (Video Cable)
Causes 'blue screen'.

Trying to correlate blue screen, and RFI/EMI interference; is a tough job; over the internet.

Laptop was in front of me, I would look for damage to the Wireless Antenna wires, first.
They loop under the right Hinge, and are just as prone to damage, as the Video/LCD Cable is.
(The Video Cable, or LCD Cable if you prefer; routes under the left Hinge)

No apparent signs of damage to the Wireless Antenna wires, (Visual inspection), I would remove the Wireless/Bluetooth Module, and clean contacts as stated above.

Blue screen occurs again, I would look into the Video Cable.

Video Cable connections are tight, then I would perform a continuity test on the Video Cable. Multimeter set to OHM's (1K), and check every wire in the Video Cable for continuity.
(Assistant for gently wiggling the cable, as Continuity test is performed. Checks for Broken/Stretched wires. Multimeter reading fluctuates when cable is gently wiggled, you know you have a broken wire)

A bad graphics chipset, will knock a laptop to it's knees. (Turns off)
Thinking is a bad Wireless/Bluetooth module, can do the same.
Knock the laptop to it's knees far enough, that no graphics are shown. There is also RFI/EMI interference, and this goes along with my thinking, that there are bad contact surfaces, or bad Wireless/Bluetooth Module.

Just my 2cents

[You open that laptop far enough to access the Wireless/Bluetooth Module, you better be wearing an ESD wrist strap; and have it's alligator clip attached to a good ground source.

Otherwise you will Static shock out the laptop, and have an expensive paperweight.
Average cost is $3 to $6 ]

I have solar panels / solar invertor with a battery backup. I am getting a lot of line disturbances. Will EMI filters help??

Electromagnetic interference (EMI), also called radio-frequency interference (RFI) when in the radio frequency spectrum, is a disturbance generated by an external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, or conduction.

My 1993 240 Volvo stops suddently after driving about 10 minuts. I am able to turn on again right away and it continues running ok. But this happens every day on my way to work near the same place. ...

Having a failure while driving past the same spot leads me to believe your experiencing electromagnetic interference (EMI) also called radio-frequency interference (RFI) when in the radio frequency spectrum.

Find more info here:
Electromagnetic interference

EMI or RFI interference typically emanates from intended transmissions, such as radio and TV stations or mobile phones. Automobile ignition systems also generate changing electrical currents and voltages that can cause EMI..

Broadband EMI or RFI interference is unintentional radiation from sources such as electrical power transmission lines.

With that said, your ignition module may be adversely affected by an outside source. Ask you mechanic if he can
shield your module to see if that solves your problem.
The ignition module is located in the front seating area, passenger side, under dash, mounted above kick panel.

PS: What happens if you drive in a different direction for 10 minutes...does the failure still happen?

1100 rough idle

Install a heavy-duty ground strap from your engine block to the battery, or check the existing ground connections. Think of the engine block as your primary "antenna" to catch positively-charged radio frequency interference -- aka electromagnetic or EMI -- energy; a solid ground connection will allow the block, valve covers and connected components to catch much of the RFI before it leaves the engine bay. This is especially crucial for engines that use coil-on-plug ignition, since the cylinder heads are completely responsible for capturing RFI generated between the ignition coils and spark plugs.

Whwn I switch on the system and even when the sound is ZERO. there is a hissing/humming noise from all the speakers. Not sure whay this sound is there.

It is noise most often referred to as E.M.I. or R.F.I. ( electromagnetic or radio frequency interference). Sources of it can come from other devices plugged into the same circuitry or from nearby running appliances containing electric motors such as fans, or fluorescent lighting.

Things that you can do to reduce this are as follows;

Relocate the receiver and/or plug it into a different outlet.

Plug the receiver into an electronic interference rejecting device such as a power conditioner.

Use ferrite clamps on your power cord of the receiver and all of it's connected devices, and on the analog audio inputs.

Move any power cables closer than about 6" to any other cables connected to the receiver, and any cables crossing each other at 90 degrees.

Make sure all of your RCA, composite and coaxial connections are completely inserted on each end and tight.

Local Radio Station Coming Through Speakers

This problem has been around since before the computer age and is quite common, it's also happened with local taxi firms in the area suddenly broadcasting on your speakers.

The reason it happens is that the speaker cable length is very close to the frequency the station is broadcasting on one solution is to pruchase a ring magnet and wrap the cable several time around it, another is to use screened cable, both are not cost effective, the simple solution is to purchase a speaker extension lead.

That sounds like its the cable. I make my own cables so let me know if you'd be interested. They have a copper shield with a polymer that blocks out noise.

Radio channel coming through on cd zone

Sounds like an internal prob within the reciever, since recievers have radio tuners in em, maybe a prob in the input switching in it. I assume you are running unbalanced rca cables out of the dvd player into the reciever as it probably doesn't have balanced input capability, unbalanced lines are susceptible to R.F.I. ( radio frequency interference ) but I doubt if that's the problem here unless maybe you are running very long cable lengths from the dvd player to the reciever. Try using a different input and see if the problems still there, can use any input other than phonograph really as they are all line level inputs.
