SOURCE: Dead Motherboard?

Testing motherboard components is beyond most users and computer shops these days, especially when it costs more to test than a new board. What you can do is do a visual inspection for physical damage; common items are -broken connectors -capacitors with rounded tops or corrosion at the base -burnt or scorched components or spots on the motherboard -corrosion on the motherboard especially around connectors, solder joints and the CMOS battery. On machines that sit idle for some time when I find physical damage its typically from high humidity, power spikes, dead CMOS batteries and damaged capacitors. Even if I find something physical I will usually replace the motherboard rather than try to fix it and run the real chance of it failing again. More often than not the physical problem we find is usually a symptom and not the actual underlying cause. Since the cost of repair parts is small compared to my labor its more cost efficient for my customers to replace the defective part with a new, warranted part. That minimized the chance of having to pay for my labor again. On the other hand if you want to experiment for the experience then go at it and have fun. Soldering correctly without damaging the part or the board is an definitely an art that takes time to learn.

SOURCE: my laptop does not want to power up

Hi Mate

You could well be wright but concidering what you have said about the battery I would try a few things first.

Clean the battery contacts both on the battery and laptop first with Braso or Autosol and then with metholated spirits. Check that the contacts on the laptop side aren't twisted or depresed. Go into a shop and ask wether you can just try a replacement battery instore with the intention to purchase if it works.

Lithium Ion batteries whilst superior to most other rechargeables in power to weight are inferior in life span. If you get 2 years out a Li-ion your doing well, every day after that is a blessing from God. In most laptops the battery acts as a sink/capacitor/regulator ie battery failure = no function.

Hope I'm rite.

SOURCE: ASUS p5vdc-MX motherboard won't boot

The light is probably the power light which is ok, but from past experience it sounds like the board is dead for one reason or other. Is it still under warranty? If it is take it back to where you got it, with the purchase docket if you have it and talk to them about what you have tested and ask for a replacement. If it is out of warranty, try ebay or use www.staticice.com.au to search for the same motherboard if you want to rebuild the system without having to reload windows.

SOURCE: computer will not startup

H there.
The beep codes you describe sound like memory issues or failure, take the system memory out, clean the contacts and the slots with a clean, soft, dry paintbrush. Re-seat the memory firmly and try boot the PC again.
Please post back with the results

Good luck and thanks for using Fixya!!

SAMSUNG GALAXY S5 - NO POWER, BATTERY, CHARGING AND CHARGER ISSUES alltabshighlighted.jpg

No power, battery, charging and charger issues

This guide contains troubleshooting steps and advice to help resolve issues you may experience when attempting to charge the handset.
After performing each step, please test to see if the issue is resolved.
Symptoms:
  • Battery not charging
  • Battery is not lasting long
  • Phone won't charge
  • Charging error
  • Failure to charge
  • Display remains black or blank
  • No power
  • Boot failure
  • Overheating
Troubleshooting Questions
  • Are you using the correct equipment?Make sure you are using an approved Samsung wall charger and USB charging cable. Other brands of charging accessories may have different voltage parameters and could cause charging issues when used with Samsung devices.
  • Have you charged your phone for longer than 30min? Leave your phone plugged in to the charger for about 30min without powering on. In some cases, it may take slightly longer for your phone to charge.
  • Is the battery icon displayed on the screen when charging? After charging your phone for a little while you should get a battery charging icon appear on the screen which will indicate that your battery is charging properly.
    If the charging icon appears, leave your phone for a little longer before you try to switch your phone on.
    If however, the screen is blank and nothing is displayed, follow the below troubleshooting steps.
  • Is the charging cable plugged into a USB port? Some charging cables can disconnect from the wall outlet adapter and plug directly into a USB port. However, when plugged into a USB port, the charging process is much slower due to the limited power output of USB ports. Instead, plug the device directly into a wall outlet to speed up the charging process.
  • Is the outlet faulty? Try a different outlet or check for a switch connected to the outlet. If possible, try powering a different device on the same outlet.
  • Does another USB cable, or wall charger work? Charging issues can occur if either the battery or charging cable is damaged. Verify that the charging contacts are clean. If necessary, clean the contacts using a cotton swab and rubbing on isopropyl alcohol.
    If possible, test the charging cable by plugging it into another device and seeing if the device charges. Alternatively, try charging the device with a different cable. This may mean changing out the cable or the adapter on two-piece chargers.
    If charging through a car charging kit, ensure that the car engine is running, and if possible try to charge other devices using other cables, through the same car kit. If none will charge, then it is likely there is a fault with the car charging kit. It is recommended to continue to cross-test devices, cables, and car kits until the problem device can be identified.
    If the device charges when using a different USB cable or wall charger, the issue most likely lies with the charging accessory. In this case, follow the approved charger repair / replacement process.
    Also, if the charger is connected via an extension or other multi-socket adapter, remove this and plug the charger directly into the wall-mounted socket. This will eliminate the possibility of a fault with the adapter.
    If you are still unable to charge your device, continue to the next step.
  • Has the phone experienced any shock or exposure to water? Accidental physical shock to a handset can sometimes cause problems to arise with battery or charger, as these components contain delicate parts, particularly. Damage can occur either to the component itself, or to the component's connection to the motherboard.
    Water exposure can also lead to damage of these components, however due to the slow way in which this type of damage can manifest itself, the cause may not always be readily obvious.
    With any physical damage of this nature, the only recourse is to contact the device manufacturer, and follow their approved repair or replacement process.

2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.

If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it

Samsung NP R70 Laptop won't charge


Most laptops will work with or without the battery and with the power adapter connected.
If the power adapter is OK, just connect it to the laptop's power socket and wriggle this plug. Does the charging LED flash as you wriggle this plug? If so the power socket may have a dry solder joint or it may be faulty. Either way the laptop needs to be dismantled to solder or replace the power socket.

Compaq wont Boot


Apart that replacing the motherboard on a laptop is a difficult and expensive operation, component inside must be tested, as the problem is not necessarily the motherboard.

Try first starting the laptop without the battery, and only power adapter.

If it still does not start, and the AC charger has the right voltage (the one written +- .5 on reading) the laptop must be taken apart and tested.

The most likely is that the AC socket on motherboard had shorted or another component near the socket had blown because of the original accident.
