If you cannot see a picture on the external monitor, the Graphics Chip might be faulty. Faulty Graphics Chips can are indicated by a regular flashing or permanent "on" state of the Power LED at the front of the notebook when you try to power it up and can be repaired by Ball Graphics Array Reflow or BGA Reballing. These repairs have an average success rate but can be expensive and must be done by an experienced specialist with specialist equipment such as an Infra Red Workstation, an Oscilloscope and a Micro soldering Station. The fault can come back. BGA Reballing generally achieves better, longer-lasting results than BGA Reflow but can be more expensive. Sometimes the surface of a faulty Graphics Chip is too damaged to fix. If the cost of Graphics Chip repair seems expensive to you compared to the current market value of the laptop, then consider buying a new laptop, having any important data transferred to the new laptop, formatting the old laptop's hard drive, offering the working components (LCD Panel, Power Inverter, Hard Drive, RAM Memory Modules, Battery, AC/DC Adapter, Wireless LAN Card, Keyboard, CPU, CPU Heatsink, CMOS Battery, Lid Frame, Chassis) of the old laptop for sale on eBay or some similar website to recoup some cash. Dismantled, functioning, 2nd User Laptop Components have far more cumulative value than an assembled, non-functioning laptop, which only has low scrap, value. A reputable, specialist motherboard component level repair centre, with specialist equipment, including an Infra Red Workstation, an Oscilloscope and a Micro soldering Station, should be test the above listed potential faults. Also, always use a surge protector for computer equipment, never directly to the mains. If the battery cells are dead, you require a replacement battery. After testing with an external monitor, I suggest you take the laptop to a repair shop for testing of the components listed above and/or a quotation for graphics chip and/or Loose DC Jack and/or Motherboard Power Management Track Bypass Repair, all on No-Fix-No-fee Terms and under a No Quibble, Free Re-Repair or Full Refund Same Fault 3-6 month Warranty.
