Compaq V5201US Notebook Will Not Start/Boot UP

No response when depressing power switch. Adapter DC output voltage is OK, and battery charging light is on (front left) when adapter connected and charging. No other response.
In following no power flowchart in service manual (V5100 Flowchart 2.2), user is instructed to "reset" power to the unit by either depressing the reset pushbutton or using a combination of the standby switch and either the lid switch or the main power switch. There isn't a reset switch on the bottom of the unit, and I cannot locate the standby switch. How do I reset power on this model?

Remove the power adapter and the battery. Hold the power button in for up to 60 seconds to discharge the laptop. Re-apply power and try booting the laptop.

My new battery will not hold a charge


Either the charge circuit in the laptop is faulty or the mains adapter is faulty.
When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

My hp compaq laptop charger is not working in the charging port but the laptop work's when the battery is charge and place in the laptop how to use the external battery port


First of all, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

DC Jack diagnosis:
1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop.

The laptop doesn't boot. Its dead. I tried connecting the charger, but it doesn't shows any signs of charging. It doesn't even show the laptop is charging.i.e no led is lit when charger is connected.Please...


Hi.

If it is completely dead check the voltage at power adapter DC contacts using a multimeter.

If there is voltage within 0.5 Volts from specifications, then try starting the laptop with no internal battery. A shorted battery may cause the laptop not starting.

If battery and adapter are OK, then the problem is the DC socket in the laptop motherboard. The laptop must be taken apart and the solder joints soldered back. This is a delicate job and must be done by an experienced repairer.

In some case the whole power circuit or the main board may be faulty. Testing is done reading Ohms at DC socket solder joints on main board (or power board, depending on model).

Regards.

Ginko.

Laptop not charging this time


Check power adapter’s DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.
If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard.

Just bought a second hand acer travelmate 4200. I have never owned a lap top. How do I change from using battery power to outlet power


On the left side, towards the rear is a DC jack. Plug the power cord in there. It should automatically start operating on AC power, and charge the battery.

Compaq Presario c300 power light blinks..


It sounds to me like there's a short in the AC adapters causing it to have enough power to charge the unit when it's not pulling power, but once it starts pulling power, it basically becomes overwhelmed and can't do both power and charge. There's also the chance that the DC jack [which the AC adapter plugs into] is bad. However I'd suggest checking the adapter first because it's simple to obtain a new one and if it doesn't work, you can most likely just return it and say it doesn't work as opposed to a dc jack being repaired which would have to be done by a professional with the skills to handle it [of course unless it's under warrenty, less than a year old, but judging by the model I'd say it's probably not]

Compaq C502US Laptop Won't Boot LEDs flash


turn it off, pull the battery from the bottom, and try it again... chances are, the power adapter is not rated properly for the notebook, or the battery is dead and won't hold a charge anymore, in which case, recycle the battery.

Dead laptop


hi there if you are having some problems with laptop starting up then i would look at the power cord that charges your battery and make shure your battery is locked in the slot as well . what type of laptop you have there ? is the power cord adapter still working ? it may not be charging your battery sometimes this will happen before you take laptop to surgury make shure that the power adapter cord is still charging battery ok to do this plug in power adapter and using a multi meter check to see the voltage that is comming from adapter plug ok on the adapter it will tell you the input voltage and the output voltage that you should be reading on your dc multimeter ok try that first ill wait on a fixya soon bye for now
