Question about Sony VAIO FRV37 Notebook

1 Answer

No power after cleaning the motherboard

I recently cleaned the dust balls from the inside of my laptop. What I didn't realize was that I still had the battery pack inside the computer. Once I cleaned out the dust balls with the air duster I started it up and everything was working fine until the power cable harness accidentally popped out of it's socket because the ribbon was so short and the power panel was not in a good position. Since I didn't realize the battery pack was still in the computer I went to put the power harness back in it's socket but couldn't do it on the first try and I saw a red light come on to the power panel on the second or third try. Now the computer won't turn on, no lights, no fan, no nothing! I took out the battery pack and just plugged it in to the regular power supply also and nothing happens and tried to reset the computer too and still nothing! Is my motherboard dead or is there another problem that is easily fixable?

    I tried the battery with & w/o the charger and just the charger and still nothing and nothing looks bad, black or smells burnt on the motherboard. I even thought it might be that I burnt out the power harness but I tried that in my other same laptop and it there goes that theory.

    HA! I got it started but it needs a new power cable harness and now there is no video, just a black screen. Any suggestions here?

Damn, you got some bad luck there. without actually haveing the laptop in my hands I can't offer much assistance.

Try to turn it on with and without the battery, then with the battery and without the charger. if noting happens after a few trys you can open it up again and look if something smells bad or looks bad (black or otherwice burned)

Of you can take the laptop to a pc repair center for analysis.

Hp 6830s is to nois. Fan is tooloude

If the fan making a smooth spin, but the noise is too loud, then it means the fan is trying to dissipate the heat. Probably the air inlet and or the air outlet (also the fan itself) is dirty (or clogged) and you need to clean it up using a canned air.
You may need to open the case/body if the dust become a dust ball (and you need a tweezer and qtip to pickup the dust ball and clean up the fan blades).

Fan making noise

There are 2 possibilities: First, your fan, air inlet and air outlet are dirty/dusty. In this case you can use canned air to clean them up. If the dust become a dust ball, then you may have to open the laptop's base or just need a tweezer to lift the dust ball. The second possibility is the fan is dying (broken). In this case, you need to replace the fan, and it is not easy (you need to disassemble your laptop) to replace the fan.

Hp pavillion dv6405us error beep code 3 1 4 3 - what does it mean? how do i fix it?

Sounds like a Phoenix BIOS Beep Code, but the 3beeps-1beep-4beeps-3beeps code doesn't come up,

[ + Beep codes for Phoenix BIOS (for older PCs) ]

1) Has the inside of the computer ever been cleaned?
2) Clean the gold plated contact pins of the Ram Memory modules, ('Stick'), and reinstall.

2a) Use a pencil eraser to clean the gold plated contacts,

Remove ALL power. Remove the AC adapter (Charger) and Battery.

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

Rub up, and down gently on EACH contact pin. (Both sides) Doesn't take much to clean them. They may not look shiny, and bright when you are done, but I assure you they are clean.

Handle the ram memory module by the BODY. The Body is everywhere on the ram memory module except for the gold plated contact pins.
The Body is coated with a see-through protective plastic.

Use air to remove the eraser dust before reinstalling. If you have a can of compressed air for computers available, use it. If not air pressure from your mouth will be sufficient.

1a) The cooling system uses air to cool the hardware components inside your laptop.
If the cooling system is clogged with 'Gunk', and cannot adequately receive the needed air flow, the Processor and graphics chipset will overheat.

['Gunk' = Dust, dirt, hair, lint, carpet deodorizer, food crumbs, etc ]

The Processor and the graphics chipset (G.P.U.) are the two hardware components that give off the most heat.

Having the laptop dirty inside can cause a serious issue also, and especially on the Pavilion dv6000 series of Notebook PC;

The graphics chipset is mounted to the motherboard with a BGA surface mount. Through constant overheating of the graphics chipset, the solder joints (Connections) may partially melt, then re-solidify when the laptop is turned off. (Cools down)

This cause cold solder joints of the graphics chipset to motherboard, and a poor contact of graphics chipset to motherboard.

The problem with the Pavilion dv2000, dv6000, and dv9000 series of Notebook PC's, is inadequate cooling for the graphics chipset.


2) Chip and Chipset are slang terms for I.C.
Integrated Circuit,

3) The integrated circuit, or chipset for graphics; is the graphics chipset, or G.P.U.,

Clean my laptop keyboard stisky

LOL, you shouldn't eat and drink over your laptop. Count your blessings that you didn't shorten your motherboard out. The best way to clean it is to probably take it apart from the computer.

Remove the power cord, remove the battery, then turn the laptop over and start removing screws from the bottom. Look inside the battery case and there might be screws there, specifically there might be some with the icon of a keyboard. Once you have the screws removed, turn the laptop over and open the lid, then pry off the strip that is over the keyboard just under the lcd screen. Once you remove it you might see more screws that hold the keyboard in place so remove them. Once all screws are removed, lift the keyboard gently because there will be a cable underneath it. Remove the cable that is attached to the keyboard and then you can clean it. I would use something like a toothpick or Q-Tip cotton swab and maybe some rubbing alcohol. You'll have to hold keys down that are around the key you want to clean to get under the key you want to clean that is stuck. Once you've cleaned it press it repeatedly to make sure it does not stick.

Samsung R519 shuts down unexpectadly

Suspect Samsung R519 is dirty inside.

The cooling system for the Samsung R519 is the Cooling Tube, Heatsink, and Fan Assembly.

The Fan Assembly consists of a Fan, and surrounding cage. (Shroud)

The Heatsink is a thin piece of metal, that has Tall, Thin, fins protruding from it.

The fan's blades, center hub, and surrounding cage may become clogged with 'Gunk'
{'Gunk' = Dirt, dust, hair, food crumbs, lint, etc}

The fins of the Heatsink may become clogged. In-between the fins, and all over the fins.

{ The Heatsink absorbs heat. It then radiates the heat way through the Tall, Thin, fins }

When a Processor overheats, (Surpasses it's Thermal Limit), it turns off.
(BIOS turns it off)
This is a fail safe feature built in. Keeps the Processor from burning up.

With the cooling system being clogged, the Processor overheats.

Solution is to clean the laptop THOROUGHLY. I don't believe at this time a can of compressed air for computers, blo-wing air from the outside, will help.

It will just push the 'Gunk' in tighter.

The laptop needs to be disassembled, and thoroughly cleaned out.
It may, or may not need new Thermal Paste for the Processor, and graphics chipset.

(If the laptop has been cleaned recently, and has this problem, it's because the 'tech' probably didn't replace the Thermal Paste.
Thermal Paste will dry up over time, and lose it's thermal conductivity properties )

Do you wish to attempt this cleaning procedure yourself?
If so post back in a Comment, and prepare for a LOT of reading.

(The R520 is VERY similar )

The above is for a Samsung X20. Posted, because I would like you to look at the last photo on the page. Here you see an average finned Heatsink, and the 'Gunk' it can collect.

I am unable to move the mouse anymore or click with the buttons, I have tried turning the access on and off as well as the laptop on and off. I am using a compaq presario cq50

If you have an old style mouse it might need cleaning. Turn it over and see if the case will slide off. There is a ball inside the case. You need to clean out the dust - you can use some canned air to get the dust out.

Satellite a85-s1072 amber light blinking on and off

try running it without he battery, check if the fan is working, could be an overheating problem.
Do you get any windows errors?
install spreedfan utility and let it read internal temperatures plus fan rpm(rounds per minute)
if it gives you a warning, the shut down, clean the intereior using compressed air only (bicycle/ball pump) to remove any inside dust or carefully disassemble the notebook + clean after you have read the manual and know which screw hold which parts.
when cleaning with compressed air, remove the lid for RAM+Harddisk+pull out the battery pack to ensure circulation! now you have made sure the fan isn't stuck with dust and can't hang... reassemble and boot up, look if fan is running...
still the prob: do come again, please
reboot and wait for error...
