|I recently started to try to fix my old laptop which is a HP G7035EA.|
I got a working charger, charges the battery, i know as it charged the laptops dead battery.
The problem i'm having is the no graphics whether internal or external screens used problem except its more complicated.
I ditched the laptop a few years ago, the last time i used it, it worked fine. now it doesn't.
There are no beeps, only drive that works is the DVD drive, hard drive gets no power, screen doesn't get power, back light doesn't come on, RAM probably works, have 2 GB sticks, tried both separately, still no luck, tried another CPU, still didn't work, removed wireless card, still doesn't work.
I narrowed it down to some random chip on the motherboard being faulty, the voltage regulators being faulty, the BIOS chip being faulty or the GPU being faulty.
The specs of my laptop + the extras/spares.
Intel celeron 540M- PGA478
Intel GMA x1300 or something like that.
120GB hard drive, tested with two caddys, works.
Intel celeron 900- PPGA478
If you need any other specs, tell me.
RAM is DDR2
The spare CPU has a 800MHz FSB but the board supports 533MHz.
I am a hardware guy not a software guy but i try to help.
