5 in 1 NOTEBOOK DIAGNOSE POST CARD

Сообщений 1 страница 6 из 6

hello,

I got recently a 5 in 1 notebook Post card and when I used the Pci-express card to debug Laptops Toshiba L300- hp620- hp6720s- platform Inventec, it showed malfunction (Displayed incomplete characters).

When checking the Card closely I noticed on it's reverse side tracks of an IC marked U4, But chip does not exist. Also, there are traces of a desoldered cap marked C9.

I googled for 5 in 1 notebook debug card images and found some with 3 chips on the reverse side, others with 2 chips, but none with 1 chip.

Could you p.s confirm that the U4 chip and the C9 cap are required for a proper functioning of this 5-in-1 Notebook Debug Card, as I intend to make a claim for the malfunction of the Card.

Your review should be well appreciated.

I don't see how to attach an image of the card.

Thank you

hello

P.S find attached photo of the 5 in 1 debug card I recently bought. The components
probably missing are surrounded by a red rectangular.

Do you share my opinion?

Thank you

This depends on the manufacturer.
Maybe it reserve space for the installation of components, which in this case is not used.

As a feed back, supplier, recognized after mails exchange with photo attachements, that the cap, is missing, but he confirmed that new cards no longer contain the IC I claimed, and they are checked ok.

He proposed either a replacement or I try to reflow display segments, fix a new cap of 100nf, and see good working of the card. If i'm statisfied, he will reimburse 20Euros as for my repair work. Not bad solution, I agreed to !

Last feed back, resoldering a new 100nf cap and reworking every pin of display segments didn't solve the incomplete characters display. Supplier decided then to send me a new debug card.
