I've same issue as yours..

Hi, Anonymous before diagnosing any turn signal/running light/parking light issue make sure the bulb is good and the light fuse has continuity with a test light. If you have replaced you OEM lights with LED lights you are going to need a load equalizer. If no turn signals work the cause could be a faulty turn signal module or the connector going to it, look for corroded, loose, or broken pins/sockets. Contact spray cleaner is great for removing corrosion. If your speedometer does not function properly it will have to be fixed first because your turn signal module gets the data from the speedometer for normal turn signal function. If your front turn signals don't work use a test light to check for power and ground at the bulb socket, then start backtracking the wiring through every wire connector to the turn signal switch/button and check for continuity, go all the way back to the fuse if necessary to find the cause of the malfunction. If your rear turn signals don't work check your rear fender wiring harness connector first for corroded, broken, loose pins/sockets, power, and a good ground, (the harness connector is usually located under the seat on the front of the rear fender) then keep tracing the wiring look for obvious harness damage caused by the rear tire. If you still can't find the malfunction backtrack from the rear fender wiring harness connector. If one side does not work you could have a faulty turn signal switch or module check for continuity.

Assuming the unit is plugged in, this could be an issue with the power supply, or an issue where the cord connects to the laptop. If the power connector on the back of the laptop is secure / doesn't feel loose or damaged, you may want to simply get a replacement power supply from a local electronics store. Be sure to take the make and model information of the laptop and the power supply with you to the store.

Hi there,
It sounds like a hardware issue, if you're getting the LED's blinking when pressing power, there IS power to your mainboard (which is a good thing). Some manufacturers have placed LED blink codes within the system to let you know what's going on, but I have a feeling it's either A) your battery or B) your hardware, such as a bad RAM stick.
Try removing the battery and with the power plug connected switch the laptop on. If it works, you've got a bad battery.
Try removing a single RAM stick or replacing both.
You could search HP Pavilion LED blink codes to further address the issue.

Hi There,
If you've got a multimeter - test your AC adapter to see if it is outputting the correct voltage for your laptop. If it is, Then you've got an HP boat anchor. Unfortunately HP laptops are known for their overheating issues, and if this is the case, a lawsuit filed against said manufacturer means you may be able to be compensated for your loss.

Power supply probably fried. You will have to take the TV apart to test.

Disk Drive works, Memory is good, so any Blinking Lights or Beeps when you hit the power button? Does anything ever post to the lcd screen when you press the power button?

It sounds like either you've got a memory issue or a video card issue. Just because the memory worked in your friend's computer does not mean it will work in yours. Your Slot where the memory goes might be bad.

When you plug in the power cord is there anylights whatsoever on the laptop, where the plug goes in or on the AC Adapter ofthe power cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Unfortunately it sounds like you have an issue with your motherboard. If you remove the battery and just try to power on the laptop using the AC adapter and it still won't power on then it's probably the motherboard. The power supply circuit (where the AC adapter plugs into) for the motherboard is integrated into the motherboard.
Sorry. If it's still under warranty Dell will replace the motherboard.

Hi,
First, we need info about your laptop brand, model, and OS
Please remove the battery, hold on power button for about 50-60 seconds, then plug-in the charger and turn the laptop ON,
Please tell us your results
Good Luck

I would look into testing the laptop by taking out the battery and plugging in solely the charger, and try turning it on. If it doesn't work, it sounds like it can probably be an issue with the Motherboard or the RAM.

Is the blinking light an amber or green color? If amber, then it might be a RAM issue. If green, the power would be on, but the monitor might not be active/working.
