the battery power runs out the computer stops working. We repair power sockets where the power pin has broken or has become
disconnected from the motherboard. In some cases the power connector
makes a poor connection with the Presario Q40 Cq70 R3479ea jack. This causes arcing
which can generate enough heat to melt the Presario Q40 Cq70 R3479ea dc jack and the

damage to the battery.

BIOS
update COMPAQ Presario Q40 Cq70 R3479ea
Many motherboards are destroyed by incomplete or corrupted BIOS
updates. A BIOS update should only be performed if it is critically
important. Don't do a BIOS update just for the sake of having the latest
version on your computer. Ensure that your computer is stable before
performing a BIOS update. Run diagnostics to check memory, hard
drive, keyboard and video graphics. In
99% of cases a failed bios update will make the computer totally unusable
so take a backup of your software and data too. Make sure that you
have a good connection to your mains adapter and that the battery is
fully charged.
