Pole sana mkuu but are you sure laptop hiyo motherboard nzima imekufa au kuna kifaa critical ndani ya motherboard ndo kina tatizo?
Unaweza kukuta ni tatizo la power IC inayotakikiwa kusambza umeme kwenye motherborad ndo imekufa.
In this post I'll explain how to troubleshoot a dead laptop and find the problem. The following troubleshooting tips are not model and brand specific, they should work for most laptops.
Let's take a look at two different scenarios. Example 1. The laptop is absolutely dead.
When you plug in the power adapter and press on the power button, there is no signs of life at all. The laptop will not make usual noises, LEDs will not light up, the fan will not spin, the screen is blank and black, etc… In short, the laptop is dead.
What you can do in this case?
1. Make sure the wall outlet is working and the laptop DC adapter is getting power from the outlet. Try another wall outlet.
2. Test the laptop DC power adapter, make sure the voltage output is correct. You can test the DC power adapter with a voltmeter.
3. Let's say the DC adapter is fine and the adapter outputs correct voltage. In this case unplug the power adapter from the laptop, remove the battery, wait for 1-2 minutes, plug in the adapter and try turning on the laptop again.
OK, you tested the adapter and it's bad. If you decide to replace the original DC adapter with a generic one, you'll have to follow this rule:
The voltage output on your new adapter has to be exactly the same as on the original adapter. The amperage on the new adapter could be the same or higher.
If nothing helps and the laptop is still dead, apparently the motherboard is fried or there is a problem with the DC power jack. It's possible the DC power jack is broken and the motherboard is not getting any power from the adapter. In this case you'll have to disassemble the laptop and replace the power jack.

Ahsante kwa ushauri mkuu, nimekupata. Nilishasoma hiyo site before, unachokisema inaweza ikawa ni kweli. Lakini nimeshajaribu kubadili moja kati ya power ic's lakini still tatizo liko pale pale, ilikuwa inawka power light na kuzima unapowasha lakini kwa sasa ndo kimya kabisa. nitajaribu kutembelea kwenye ebay nione gharama itakuwa vipi.
