In above laptop, inserting adapter only charging led lit, but pressing 'on' switch no power , no display, no leds at all. suspected mobo, disassembled. near dc jack, ic "max1907a etl" found, but can't find datasheet for it. checking offline, some power-mosfets nearer to ic(both sides of mobo) showed as shorted. but while removing cpu, those mosfets were found ok; checking with multimeter. I sent to repair-shop for cpu replacement. they said mobo must be replaced. not another option. please help me, please.

You can try doing these:

Clearing the CMOS, i.e. Unplug power cord and take out battery, then put them back in.

Cross check the components such as heatsink/fan, video card, and processor. It is never good to have a heatsink with the fan not spinning.

Check to see if the heatsink is cold, warm or hot. It shouldn't be cold OR hot.

Be sure to use an ORIGINAL Sony transistor and be sure to resolder the pins of the small horizontal driver transformer and all parts connected to and around it, and your set should be fine.

I have not worked on your particular model. But, I have serviced many TV sets over the years. My answer will ge generic.

Check all the capacitors in the horizontal output stage and power supply areas for high ESR. All the caps that are out of spec must be changed.

The high voltage multiplier & flyback can also cause the fault you are having.

You have to consider that the DC voltages are not the only important spec that has to be met. There are also many power drive signals that work with reactive devices. If there is any defect in the critical areas there will be failures.

Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard. This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

Battery problem with HP Compaq Presario V2000 laptop


When batteries fail, they usually lose the cells inside them, which means that the cell is no longer able to function as a holding cell for power and therefore cannot do its job anymore, when a battery fails to hold and refuses charging it is bad and needs to be recycled. The flashing is telling you to purchase a new battery. The larger the number of cells in the battery, the longer and better it will perfrom,,RE: 6 cell, 9 cell, 12 cell.

My Compaq Pres V2000 laptop does not get on with power on switch


Take out the battery and only hook up the AC Adapter to see if the laptop turns on. If it does then you know the battery is shorting out the laptop and either has very little power to turn on the laptop or is shorting out the laptop cause its bad.

If you don't get the laptop to turn on, make sure your using a well known working wall outlet to plug the laptop to and only use the AC Adapter. If you AC Adapter is hooked up and the Green Led turns on then you know the adapter is good.

After those two steps, you can also try taking out the dvd drive and the hard drive. Then try turning on the laptop and if the laptop still doesn't turn on then the motherboard is bad in the laptop.

I have a compaq presario 700 laptop that is no longer charging.


The notebook battery may have a defect if it will not power on the notebook and if it will not hold a charge. The battery indicator light on the notebook either does not light or always blinks orange. The notebook operates correctly when connected to the AC adapter.
A battery that will not charge may be the result of an AC adapter failure, a system board failure, or a battery failure. Perform the steps below to diagnose the failure.
Troubleshoot the power supply
To verify that the AC power supply is functioning properly, follow the steps below.

1.
Plug the AC adapter directly into a functioning wall outlet, and plug connector into the computer. Do not plug into a power strip, surge protector or secondary power source.
2.
Verify the following operation and take the appropriate action:
*
That all power cord connections are secure.
If the AC adapter connection to the notebook is loose, the connector may be damaged and require repair. Contact HP service and support for further assistance.
*
That the power button or power LED is lit when the computer is on.
*
That an LED on the AC power supply adapter is lit when plugged into an AC wall outlet (not available on all AC power supply adapters).
*
That the AC power supply adapter is the correct type.
Different notebook models require different AC power supply adapters. You will need to know the Product Number of your notebook to determine the Part Number of the replacement part. Click Start > HP Help & Support to view the product name, product number, and serial number that you'll need to have to speak with HP Customer Service.
View the See Also section for information about locating HP Help & Support in your operating system.

Troubleshoot the System Board
If you've verified that the AC power functions properly, troubleshoot the PC's system board by following the steps below.

1.
Remove the battery, and keep the notebook connected to AC power.
2.
Press and release the Power button to start the computer.
*
If the notebook PC powers on , then the AC adapter and system board are functioning properly. Go to Troubleshoot the battery .
*
If the Power LED is off , then the AC power adapter needs to be replaced. Contact HP Service and Support for further assistance.
*
If the power LED is on , but the notebook PC does not power on, then the notebook PC needs to be repaired. Contact HP Service and Support for further assistance.
3.
Shut down Windows by selecting Shut Down from the Start Menu.

Troubleshoot the battery
If you have verified the AC power supply and system board are functioning correctly, troubleshoot the battery by following the steps below.

1.
Insert the battery into the battery compartment on the bottom of the notebook PC.
2.
Connect the AC power supply and allow the battery to charge for 15 to 30 minutes.
NOTE: The Battery Charging light should be on while the battery is charging. If it is not on, check the AC power adapter connection to the notebook PC.
3.
Unplug the AC power adapter cord from the notebook PC.
4.
Press and release the Power button to start the computer using only the battery as the power source.
*
If the PC does not power on, then the battery needs to be replaced. Contact HP service and support for further assistance.
*
If the notebook PC does power on, the battery is functioning properly.
NOTE: If you have purchased a second battery for your notebook PC or you have access to an identical battery, you can also check the battery by inserting the second battery into the PC and performing the Troubleshoot the battery steps again.

Battery not charging...but is recognized by V2000


My guess since the battery checked fine in another laptop would indeed be the charging board or charging circuit on the motherboard.
