NOT GPU but the NB. GPUs Ati on these models have minor problems against that damned NBs.

Re: Hp dv5

that gpu 3470 is most failure gpu from ati. it is even very bad for reballing, because of its sensitive for heat.

that notebook would fail. just wait :-)

Re: Hp dv5

I've done dozens of DV5 and DV6 and only 2 had bad GPUs. It was the northbridge almost every time. Sometimes it requires replacement as it either does not hold up or refuses to display video even after reballing.

Re: Hp dv5

IGP reballing is a waste of time .. entirely major part of they problems are situated on the internal bumpers , so there is no need of adding new balls under the chip ... the problem is internal so each time you heat it up , it works due the the internal part start making contact after heat cycle .
best way is to replace a problematic chip ... happy costumer , and good word for your lab !

Re: Hp dv5

The Unique: same experience, just 1 bad GPU HD34xx, but loads NBs

highpulse: IGP after reballing on DV5 works more than year usually, so it is not a waste of time, if customer don't want to pay double price
