heh, the dv-series.... really nice exterior, but, inside, poor choices
in cable routing, increased use of polymer ribbons prone to breakage and
open circuit from even a single disassembly (lint/dust is the #1 laptop
killer, they have to be cleaned out regularly, no less than twice a year
in most environments), undocumented screws and chinese finger puzzles,
undocumented cables, incorrect instructions, parts that don't exist,
parts that exist but aren't documented, incorrect part numbers....
Interestingly, my primary laptops (two of them for me, and one for the
lady) are Compaq C-300 series (upgraded to the 945GM motherboard and
T7600 65nm Core2 Duo) are reliable to the extreme, well-documented
(except for that one screw with the silk-screened arrow pointing at it
in the upper left of the mobo), a complete airpath cleaning with
practice can be done in about an hour with three screwdrivers, a muffin
tin, pad and paper (which screws in which muffin hole), a toothbrush,
unscented toilet paper (wipe the silicon to a mirror finish again), and
arctic silver 5. The series is also labeled as the HP G-3000 series.
The Compaq C-500 series is in the same chassis with only minor changes.
The problem lies in that most of these were sold with the 940GML chipset
(Celery only), but 945GM was an option and those mobos are about $100
USD +- $30 USD on eBay, mostly HannStar refurbs from China. These were
introduced in 2007, and must be flashed to the most recent BIOS before
putting in a Core2 Duo T7200 to T7600. My only complaint under BSD has
been the Mini-PCI has bad ACPI, as the broadcom and intel driver both
will panic the system at the worst, or at minimum refuse to load the
driver with a "could not allocate resource". No biggie, it works under
winblowz xp and 7. Under BSD, just use a USB wifi. Interestingly,
under SuSE, the NDIS driver for the broadcom wifi does work.
Conclusion: Get a Compaq C-300 or C-500 series system, preferably
non-working (most likely a 940GML/Celery anyway), put in a good 945GM
replacement board, and you will have a reliable, reasonably recent,
low-cost laptop, just remember to clean it out when idle is in the mid
to high 70's Celsius.
The newer dv-series laptops are slick and all that on the outside, and
very tempting when you play with it at the store, but they were made
with the intent that people throw them away instead of having regular
maintenance performed (cleaning), based on the number I have repaired,
all needing new motherboards. Don't spend $800-1500 on a laptop that
will fail in a year or two and be that hard to clean without having to
buy replacement parts (ribbons, cable bundles, etc). STAY AWAY FROM HP
dv-ANYTHING ESPECIALLY!!! THE AMD VERSIONS ARE EVEN MORE PRONE TO
