Hey guys,
Few problems with the laptop
It is an HP DV6-2110EA, running Intel® Core i7-720QM Processor.
The problems:
Main problem is that the CPU will not go above 1ghz, no matter what you do.
The other problem is that it now will not charge. It's odd, because the battery has some power left, but the laptop won't turn on with just the battery, it will only turn on and work if the PSU is plugged in to it. Now, you can unplug the PSU once the computer has booted, and it will run off the battery, but it won't power from the battery, and won't charge the batter either.
Any ideas what could be the problem? Could it be a motherboard replacement job? Or something more simple and less expensive than that?
Thanks in advance guys
