Modem problem
Disconnect the phone line from the modem and connect a normal phone to this phone line. Lift the handset and check it you have a dial tone and see if you can dial out.
If you don't get a dial tone then there is a fault with the phone line and it needs to be repaired before you can use your modem.
Dell C640 Turn On Problem
Probably an overheating problem. The best thing would be to disassemble your notebook, and clean the heat sink. If you're not experienced with this kind of things, don't do it. You can try to use a vacuum, or take it to a specialist.
How to fix my dell E4310 from freezing while im using it?
There are a number of reasons that the unit could be freezing up.
- Corrupted file(s)
- Low available disk space
- Viruses and/or malware
- Too many add-ons/toolbars/etc.
- Heat build-up
Number one is the hardest to find. So start with #2. The computer needs free hard drive space to operate. If the disk is nearly full or is very fragmented, this can slow the machine to a crawl. Check for available space and if there is plenty (20GB or more), then check for fragmentation under administrative tools. If the defragmentation tool recommends optimization, allow it to perform it and see if that helps.
For viruses and possible malware, run your virus scanner. It is always a good idea to get a second opinion on such things. Malwarebytes is a free malware scanner that works very well to find adware and some things that many antivirus programs fail to detect.
Many user feel that they have to have every bell and whistle. I've seen some browsers with 7-10 different toolbar add-ons. These almost always come with some adware and always slow down the browser. Uninstall all but the most essential toolbars for the best performance. Heat is a slayer of machines. Laptops are very susceptible to heat issue since they are often placed on beds, sofas, carpets, and yes, even laptop. Many of these units draw cooling air from the bottom and exhaust it to the side. Even those that draw air from the rear and exhaust to the side will often intake large amounts of dust, grit, and lint. These can partially or completely clog the heat sink unit and cause heat buildup of the processor. This will cause the processor to work slower and can actually cause it to thermally lockup, resulting in the need to reboot. Many units can be accessed to clean with a removable cover on the bottom; others may need to be serviced by a technician to clean.

Can you hard wire power to laptop?
NO
if you do, a noob will blow it to kingdom come. as in letting the smoke out.
the power-pack does 3 things
it has the correct DC voltage and wattages
and #2 prevents fire when the PC fails and things short inside.
and prevents huge damaging surges landing inside the PC
buy used power pack off fleabay and win.
i bet I'd mow one lawn and and buy one
