Step 1: What the problem could be
Here is how to open it and possibly fix the problem.
I must tell you , this laptop suffered from a shorted out wire before this problem. I had to replace the power cable, inside the computer, between the screen and the power supply.
I had heard of people on the web, replacing there batteries with the same problem. Before trowing out that battery, or exchanging it from a refurbishing place, have a look at the fuse.
Step 2: What you will need
I got the screwdriver for a few dollars on the web on eBay.
the model is 360/ X50 from yaxun
look up eBay for Tri-wing trigram screwdriver
Step 3: Take the screws off the
Remove the 2 tri-wing screws using the special screwdriver I mentions before.
Step 4: Remove the cover
Step 6: Locating the fuse
If the fuse is actualy blown, un solder it, and replace for a new one.
I sourced it at Digikey, the part number is F2891CT-ND .
It's a 7V 32V fast type
Step 7: Put the battery back together
Of course, if your battery is totally dead. The LED will not turn on.
In that case you will have to charge it a bit after reassembling it.
Put back the battery in reverse order.
