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.Have you already looked on the Dell web site?

The SERVICE tag is listed in the BIOS.
I can safely say you need a new charger...+patio I have already bought a new charger for it, and it doesn't want to power on, as I said in the thread start. Tho the new charger only has 3.44A and the original one has 4.52. Could that stop it from powering on? BTW, the battery doesn't charge, so it is 100% relied on a charger.

+Geek-9pm I don't know what to look for on that site. I need the info posted in this thread so I can read it, I don't have the time to search a lot.Yes...the charger needs to match the old one... Quote from: patio on October 15, 2016, 06:29:19 AM

I have  two Inspiron 1525's.
Remove the HDD & the battery & see if it will stay on & enter the BIOS.

The power brick you have should be enough to do this.
