Hi! I have been given a Dell Studio 1535 to fix: the laptop isn't turning on and before, when it did power on, it worked slowly. The charger was in a really bad shape, tho I tried to power it on anyway, and it did power on, but for 5 seconds,enough time for me to get in BIOS settings. There, afyer 1 second I reached them, it died because the charger was moved 1 mm. Since then, the laptop never powered on again. I even replaced the charger, which besides it tries to charge it in every position I insert it in the charging jack, it did nothing. The original charger had 4.52A, but the newer one has only 3.43A.
We have 2 possibilities:
1. Trying to PO (power on) the laptop with a battery: the charging LED blinks red 4 times and white once.
2. Trying to PO the laptop without a battery: the charging LED stayes on for 2 seconds and then it shuts off.
In neither of these possibilities the laptop turns on.
