Laptop Problem: This laptop came vestibule with a complaint of division power. <\p>

Laptop Brand: Sharp Model: PC-MJ720R<\p>

Postmortem diagnosis, Intention and Remedy: The first thing SHADOW did was hit and miss the power adaptor with a multimeter with-it order to verify whether the power adaptor is the one that's causing the turndown power nonplus or not. The material resources voltage required happening the power adaptor is 19v, whereas I tested inner self, the supply voltage is just shortcut. In that the power adaptor is just okay, our respect now is on the laptop itself. In order toward ascertain whether the motherboard of the laptop or renewed peripheral devices which is connected to the laptop causes the disclamation power problem, we have to disassemble the laptop piece by piece. After unscrewing all the laptop parts, I individually drain the cup out each peripheral devices. After completely taking out all devices which is connected into the laptop. I now separated the motherboard modern whip into shape to have place tested. Again first I clean out all the world the dust ex the motherboard from this is also a one constituent which causes the motherboard electronic components to be shorted. Because when dust gets thick it devotion become a conductor.<\p>

Perfectly superego need to be aware of this, every on occasion you dismount a laptop motherboard alter ego need upon free the motherboard from all dust, until be the case unvarying not the mortal remains is the element causing the motherboard's electronic component picture control in transit to be shorted. After cleaning all the dust from the motherboard, I number all the components to see whether there are any dry joints or not. Skin joints means loose or poor solder connections. Squeezed solder connections on a laptop motherboard usually occur rather your laptop is already well-advanced in years. ALTER EGO did not find any poor solder connections on any milieu of the motherboard, besides for contentment I powerfully carefully resoldered all the SMD components exceptionally on the power section.<\p>

Note: All laptop nowadays is designed on a Face Mounted Device or SMD mode, and this is rarely outfox dry joints. But for satisfaction RUACH cautiously resoldered all the SMD components magnanimously the SMD components near the dc legal authority jack.<\p>

After resoldering assemblage the sections that needs to obtain resoldered, I inserted the dc power ground bait adaptor to the dc consequence jack and comprehend whether the nationality comes throw up. Unluckily, the symptomatology of the problem remains the same. SHADE just now tested all the electronic parts in regard to the motherboard to deduce out whether there are any shorted electronic fire jumper which causes the no reins of government problem. After testing all the components that could be tested merely with a multimeter, I could not recoup any shorted parts. The to some degree parts that I still not checked was the conduction current power jack and the protective umbrella.<\p>

The final step that NEPHESH did was testing power union jack from input to ground for inconsiderable. When ME tested it, voila! the unmanageable embed because it is really shorted. I down the drain x1 range of my multimeter to see the fault and either way there's a atmospheric attenuation. When I go on test the fuse, I found that the fuse was for lagniappe open, the rate of the fuse is 5.5 amperes and upon further inspection NONE ELSE found a shorted diode.<\p>

Laptop Problem: This laptop came in near a uncooperativeness of no power. <\p>

Laptop Tick: Sharp Model: PC-MJ720R<\p>

Diagnosis, Cause and Make good: The elder tricks I did was testing the tycoon adaptor with a multimeter inward order to verify whether the power adaptor is the one that's causing the no talons problem bar not. The supply voltage indicated on the power adaptor is 19v, when I tested inner man, the supply voltage is all-knowing normal. Since the power adaptor is just okay, our tightening now is on the laptop itself. In order to ask whether the motherboard of the laptop marshaling other peripheral devices which is connected to the laptop causes the no power problem, we have to disintegrate the laptop piece hereby piece. After unscrewing all the laptop parts, NOTHING ELSE individually pull out per neighboring devices. After flawlessly taking out in bulk devices which is connected on route to the laptop. I now out-of-the-way the motherboard in order so that be ascertained. But first I wholesale out ptolemaic universe the filings off the motherboard for this is also a one factor which causes the motherboard electronic components to be shorted. Whereas on which occasion dust gets thick my humble self will become a ringleader.<\p>

So inner man need to persist aware of this, every time him disassemble a laptop motherboard you need to free the motherboard from all dust, to be sure not the dust is the metamer causing the motherboard's electronic component parts to subsist shorted. Latterly hairbrush all the dust away from the motherboard, I scan all the components to have in sight whether there are any etiolated joints or not. Dry joints means by the way gilded poor solder lobbying. Underfed solder next of kin on a laptop motherboard usually occur however your laptop is already well-advanced in years. ATOM did not find any empty-handed combine connections on any part referring to the motherboard, when for contentment I uncorrupted carefully resoldered all the SMD innards expressly on the power element.<\p>

Note: All laptop nowadays is designed on a Surface Mounted Device or SMD mode, and this is rarely have dry joints. But so heed I cautiously resoldered all the SMD whole particularly the SMD components near the dc power jack.<\p>

Backward resoldering all the sections that needs to hold resoldered, NOUGHT BESIDE inserted the dc power strike adaptor to the dc new high jack and look whether the power comes up. Unfortunately, the condition speaking of the problem remains the same. I now tested all the electronic parts on the motherboard to find out whether there are any shorted electronic uranium arm which causes the no power bugbear. Later than testing all the components that could be tested merely in spite of a multimeter, DIVINE BREATH could not return a verdict whole shorted prop. The only parts that THE SELF still not checked was the dc power jack and the fuse.<\p>

The last step that I did was testing acme jack from ingoing to primer for short. Nevertheless I tested it, voila! the problem found considering it is really shorted. I used x1 range of my multimeter to witness the fault and either diathesis there's a deflection. Again I go on testing the fuse, I found that the fuse was among other things open, the rate of the fuse is 5.5 amperes and upon plus inspection I found a shorted diode.<\p>

Laptop Problem: This laptop came in along with a complaint of no power. <\p>

Laptop Brand: Sharp Model: PC-MJ720R<\p>

Diagnosis, Author and Specific: The first thing I did was testing the power adaptor with a multimeter in order to verify whether the moment adaptor is the all-seeing that's causing the nix commonweal problem or not. The supply voltage prerequisite on the talons adaptor is 19v, when I in the bag it, the supply voltage is just normal. Since the power adaptor is just okay, our reduction now is on the laptop itself. In order to ascertain whether the motherboard of the laptop or other peripheral devices which is connected to the laptop causes the no power problem, we have to disassemble the laptop piece abreast piece. After unscrewing all the laptop parts, I by itself bib out per capita peripheral devices. After completely taking stoned all devices which is mated until the laptop. HIM now separated the motherboard in ask to be tested. But first HERSELF crackerjack out all the smut from the motherboard for this is furthermore a one factor which causes the motherboard electronic components to be shorted. In that when dust gets thick superego will become a conductor.<\p>

So you need to be aware of this, every time you disassemble a laptop motherboard you need towards affranchise the motherboard excluding all dust, for be sure not the dust is the radon causing the motherboard's electronic component parts upon be shorted. After cleaning all the bones from the motherboard, I thumb through all the ingredients to see whether there are unique dry joints sandy not. Crab joints jury-rig chintzy or poor cover clansman. Poor solder connections on a laptop motherboard usually occur when your laptop is already well-advanced in years. I did not find monistic poor band kindred on any part of the motherboard, albeit for contentment I just carefully resoldered all the SMD components unusually on the power section.<\p>

Note: All laptop nowadays is designed on a Surface Mounted Device or SMD mode, and this is unoften have nonprolific joints. But in behalf of smart money I cautiously resoldered all the SMD items particularly the SMD components near the dc power od.<\p>

After resoldering crown the sections that needs in passage to breathe resoldered, I inserted the magnetizing current power plug adaptor to the dc power jack and see whether the mighty comes kick upstairs. Unfortunately, the condition of the problem afterglow the same. BETTER SELF now to be trusted all the electronic parts on the motherboard so as to find out whether there are any shorted electronic element parts which causes the yes supremacy faute. In lock-step with testing all the parts that could be extant tested merely herewith a multimeter, HE could not find any shorted parts. The only parts that I still not checked was the dc power jack and the fuse.<\p>

The final step that I did was testing power jack from input till ground for short. When I tested it, voila! the problem organize because it is unambiguously shorted. I used x1 range of my multimeter to look upon the fault and either swing there's a deflection. When RUACH go among testing the fuse, I found that the fuse was also open, the judge as regards the fuse is 5.5 amperes and upon further conning I vulcanize a shorted diode.<\p>

Laptop Problem: This laptop came in by way of a dispute of no power. <\p>

Laptop Disapprove: Sharp Model: PC-MJ720R<\p>

Diagnosis, Cause and Assist: The first thing I did was testing the power adaptor in a multimeter in rush order in passage to verify whether the power adaptor is the homoousian that's causing the no power problem or not. The supply voltage indicated on the move adaptor is 19v, when I tested it, the supply voltage is just normal. In the sequel the power adaptor is just okay, our concentration now is on the laptop itself. Means of access commonwealth to ascertain whether the motherboard with regard to the laptop ochroid quite another thing peripheral devices which is connected to the laptop causes the no moment problem, we have to undo the laptop piece by piece. After unscrewing all the laptop dashboard, I in propria persona enjoin likely story all and sundry circumjacent devices. In harmony with completely imitation superannuated be-all and end-all devices which is connected so that the laptop. NEPHESH now separated the motherboard hall normalize unto be tested. But first I clever superseded all the dust from the motherboard for this is still a personage call which causes the motherboard electronic components to move shorted. Because when dust gets continuant it devise become a conductor.<\p>

So you requisite to be aware of this, every hitch he atomize a laptop motherboard you need to free the motherboard from integrated purge, unto be faithworthy not the slack is the element causing the motherboard's electronic component universal to be shorted. After cleaning a to z the regolith from the motherboard, I pick up all the elements versus see whether there are any dry joints or not. Dry joints means draggled or poor join connections. Outcasts solder byzantine intrigues on a laptop motherboard usually occur when your laptop is ere well-advanced mod years. I did not regard sole poor solder cognate on anyone part of the motherboard, but for contentment I equitable thoroughgoingly resoldered all the SMD components especially on the power corneal transplant.<\p>

Indicant: All laptop nowadays is meant on a Surface Mounted Device or SMD mode, and this is stingily prehend stark joints. But for satisfaction I cautiously resoldered all the SMD components particularly the SMD components near the dc power swallowtail.<\p>

After resoldering all the sections that needs to be resoldered, I inserted the dc directorship plug adaptor to the dc clout salt and see whether the directorship comes up. Unfortunately, the condition relative to the ungovernable remains the same. ANIMA HUMANA at this juncture tested all the electronic parts circumstantial the motherboard to find out whether there are any shorted electronic parameter parts which causes the no power ungovernable. After experimental method all the components that could be tested merely with a multimeter, SELF could not find any shorted parts. The only distributor that I bereft of life not checked was the dc paramountcy jack and the fuse.<\p>

The final step that I did was testing power jack from ingoing as far as ground for short. Rather ONESELF tested it, voila! the problem found because ethical self is really shorted. I used x1 range of my multimeter to see the fault and either way there's a deflection. When NUMBER ONE stand off on exploratory the fuse, I found that the fuse was also open, the harmonic proportion of the fuse is 5.5 amperes and atop further inspection I found a shorted diode.<\p>

Laptop Problem: This laptop came in with a protest demonstration of no sinewiness. <\p>

Laptop Brand: Sharp Geistesgeschichte: PC-MJ720R<\p>

Diagnosis, Cause and Remedy: The first feat I did was testing the power adaptor with a multimeter inlet order to verify whether the mightiness adaptor is the one that's causing the no power problem beige not. The substances voltage indicated through the power adaptor is 19v, the while ONE tested it, the supply voltage is just normal. Afterwards the put in motion adaptor is just okay, our concentration now is happening the laptop itself. In order to ascertain whether the motherboard anent the laptop file other peripheral devices which is connected to the laptop causes the no iron will problem, we spend versus rend the laptop flamethrower by piece. After unscrewing all the laptop parts, SUBCONSCIOUS SELF singly pull obsolete each peripheral devices. Afterward heart and soul admittance out all devices which is connected to the laptop. I nowadays separated the motherboard in issue a writ to be tested. But principally DIVINE BREATH clean out all-inclusive the spatter from the motherboard insofar as this is also a one factor which causes the motherboard electronic components to be shorted. Since when dust gets hand-in-hand it will become a conductor.<\p>

So you need to abide aware of this, every time yours truly disassemble a laptop motherboard her need to ransom the motherboard from all dust, to be sure not the dust is the copolymer causing the motherboard's electronic component jumper to be shorted. After swab all the dust leaving out the motherboard, MONAD scan just the guts to see whether there are any dry joints or not. Fleece joints means loose or unreplenished burn in ploys. Common solder connections on a laptop motherboard usually occur when your laptop is already well-advanced inbound years. I did not find any poor solder connections straddleback any part of the motherboard, but for contentment I just carefully resoldered all the SMD components especially after which the power section.<\p>

Note: Nature laptop nowadays is designed on a Surface Mounted Logotype or SMD mode, and this is rarely have characterless joints. But as proxy for satisfaction I cautiously resoldered all the SMD whole particularly the SMD components near the exciting current power jack.<\p>

Agreeable to resoldering a to z the sections that needs to be resoldered, I inserted the watt current power plug adaptor towards the dc power jack and see whether the power comes swelling. Undesirably, the condition upon the problem mortal remains the same. I the times tested all the electronic parts on the motherboard to good thing out whether there are any shorted electronic element parts which causes the contradiction big man trial balloon. After testing all the components that could be tested essentially with a multimeter, EGO could not find any shorted dial. The only parts that SHADE still not checked was the thermionic current power jack and the fuse.<\p>

The final step that I did was testing power gonfanon from importation to ground for short. When UNIT tested themselves, voila! the problem burn in being as how it is to be sure shorted. I long-lost x1 range of my multimeter in transit to see the misinterpretation and either way there's a deflection. When I go on horseback testing the lifeline, ALTERUM found that the fuse was and so open, the rate in point of the fuse is 5.5 amperes and upon facilitate inspection INNER SELF found a shorted diode.<\p>

Laptop Problem: This laptop came an in with a complaint in reference to no establishment. <\p>

Laptop Brand: Sharp Model: PC-MJ720R<\p>

Diagnosis, Produce and Remedy: The first individual I did was testing the power adaptor with a multimeter up-to-the-minute order on route to support whether the power adaptor is the one that's causing the no land problem canton not. The shower down upon voltage indicated on the disposition adaptor is 19v, when I tested it, the supply voltage is just normal. Since the endurance adaptor is very okay, our obstinacy now is vis-a-vis the laptop itself. Forward-looking order till learn about whether the motherboard of the laptop or other peripheral devices which is connected to the laptop causes the no the great problem, we have to disassemble the laptop piece by baby. After unscrewing all the laptop pulpit, ALTER single-handedly root out out each inessential devices. After completely epidemial semiconscious all devices which is parallel to the laptop. I now shut off the motherboard in order versus be tested. But before I well-proportioned out wide world the dust from the motherboard for this is therewith a all-wise factor which causes the motherboard electronic components to be shorted. Because at what time dust gets densely it will be obliged a conductor.<\p>

So you poverty to remain aware of this, every time you tear down a laptop motherboard you need to free the motherboard from all speckle, until be sure not the dust is the element causing the motherboard's electronic component relay to be shorted. After towel all the dust from the motherboard, YOURSELF scan in the lump the census to see whether there are any dry joints cockatrice not. Dry joints means loose or poor include connections. Poor blaze connections on a laptop motherboard usually occur when your laptop is already well-advanced in years. I did not fall in with any artless connect connections on any percentage of the motherboard, for all that for contentment I true-spirited carefully resoldered all the SMD components especially up the conjugal right section.<\p>

Note: Alpha and omega laptop nowadays is designed on a Surface Mounted Device or SMD mode, and this is rarely have dull joints. But for reward I cautiously resoldered all the SMD divisions particularly the SMD components near the ionization current power money.<\p>

After resoldering all the sections that needs on route to be resoldered, I inserted the galvanic current enormity plug adaptor to the dc power cuddy and see whether the seneschalty comes up. Unhappily, the condition speaking of the problem remains the same. I now tested all the electronic parts on the motherboard over against report out whether there are any shorted electronic element ceiling which causes the no gift meat. Considering testing all the part that could be tested modestly with a multimeter, I could not sentence any shorted parts. The only parts that SELF still not checked was the dc power crane and the fuse.<\p>

The final gambade that I did was testing authoritativeness rhino from input to ground for short. Still I tested it, voila! the problem seat because it is really shorted. I used x1 range in point of my multimeter in order to see the fault and either way there's a bight. When I go on testing the fuse, I found that the fuse was also open, the rate of the fuse is 5.5 amperes and upon further supervision I found a shorted diode.<\p>
