Faulty Dell Laptop purchase in need of repair

Моя проблема

A complete laptop in good condition purchased from ebay, with the problem that power on caused brief flicker from the led's in the bezel, then nothing.

As there was no response from the M90, I thought that the Intel T5300 processor may have blown, as with a broken graphics adapter there is usually some response. However, after purchasing a new condition Intel T2400, also from ebay, the problem was unaffected, so I watched a video by Gold Lark called shake'n'bake which repairs a bakeable nvidia geforce video card, similar to the nvidia quadro unit in this M90, and following this procedure using the suggested 200C, 10 minute bake resulted in a working laptop!

The upshot of this is that the socket 478 m/board accepts most Intel T series processors, up to T7600, I read on a Dell forum. I found that the hardware supported graphic resolution of the laptop (some M90's have an unusual 1920*1200 WUXGA+ resolution), which, possibly due to the new processor, had changed to 1440*900 WXGA+, a resolution that most good games support without exhausting the capabilities of the 256MB graphic adapter. As I did not know of this before I attempted this repair, I found it intriguing, also quite cheap, as Intel T series processors can be difficult to obtain at a cheap (£5-10) price.
