Mi HP DV5-1237la no enciende/ My HP DV5-1237la doesnt start. por favor ayuda!

Este es mi HP DV5-1237 la. un dia lo deje hibernando y cuando lo volvi a abrir estaba apagado, imagine que se habia ido la luz pues la bateria no sirve, pero no, nunca volvio a prender. Estoy casi seguro de que no es el chip de video porque no prende nada, si fuera eso prenderia y me daria un codigo de error, al igual que con el disco duro, la RAM, o la board. gracias por ver mi video y por guiarme a reparar este portatil, pues no tengo dinero como para mandarlo a un tecnico que me cobre una pequeña fortuna, ademas de que el computador tiene mas valor sentimental que monetario. This is my HP DV5-1237 la. one day i left it hibernating and when i opnened it again it was dead, i thought the light was off, because the battery is broken, but it never started again. im pretty sure its not the video chip cause it doent even start, if that would have been the case it would start and give an error code, like in the case of a broken Hard drive, RAM and even board. thanks for watchig my video, and giving me guidance towards fixing my laptop, since i dont have a lot of money and i dont wanna pay a little fortune to a technician. plus the computer has more sentimental value than monetary. answers in english are also welcome!
